Not Your Parents’ Pot: Cannabis Is More Potent Now

By Dr. Ty Schepis

Eventually, most adults reach a point where we realize we are out of touch with those much younger than us.

Perhaps it is a pop culture reference that sparks the realization. For me, this moment happened when I was in my late 20s and working with adolescents in school settings to help them quit smoking. When other drugs would occasionally come up, I didn’t understand some of the slang terms they used for these drugs. Many people may have that feeling now when the topic of cannabis comes up – especially in its different and newer forms.

As a professor of psychology, I focus my research on substance use in adolescents and young adults. A major change during my time in research is the legalization and explosion of cannabis availability across the U.S.

There are arguments for and against increasing legalization of cannabis for adult use in the U.S., but expanded access to legal cannabis also may have unintended consequences for adolescents. These consequences are compounded by the increasing potency of some cannabis products.

I use the word “cannabis” since it refers to the plant from which the drugs are derived. It also serves as a catch-all term for any substance with chemical compounds from cannabis plants and addresses concerns that the word marijuana has some long-standing racist overtones.

Cannabis now comes in a larger variety of forms than it used to. When most people over 40 think of cannabis, they imagine its dried form for smoking. This cannabis was not particularly strong: The average THC concentration of cannabis seized by the Drug Enforcement Agency in 1995 was 4%, while it was roughly 15% in 2021.

In addition to the smoked form, some might remember an edible form, often baked into a dessert like a brownie, or hashish, which is derived from more potent parts of the cannabis plant.

Today there are many different cannabis concentrates that have high levels of THC, typically ranging from 40% to 70%, and more than 80% in some cases, depending on the method of extraction. These include oils that can be vaporized by vape or dab pens, waxier substances and even powders.

Differences in Cannabis Products

THC and cannabidiol, or CBD, are the most common chemicals in cannabis. Each one interacts with the brain in different ways, producing different perceived effects.

CBD does not produce the same “high” that THC does, and cannabidiol may have benefits as a medication for severe epilepsy, as well as other potential but as yet unproven medical uses. The differences between THC and CBD come from how they interact with cannabinoid receptors – the proteins onto which these drugs attach – in the brain and body.

However, CBD can also make people sleepy, alter mood in unintended ways and cause stomach upset. Never use a CBD product without consulting a physician.

THC is the chemical most strongly associated with the high from cannabis. By increasing the amount of THC, concentrated products can increase blood levels of THC rapidly and more strongly than nonconcentrates such as traditional smoked cannabis.

Cannabis concentrates also come in many different forms that range from waxy or creamy to hard and brittle. They are made in a variety of ways that may require dry ice, water or flammable solvents such as butane.

The myriad names for cannabis concentrates can be confusing. Concentrate names include “budder,” which refers to a yellowish paste like frosting; “shatter” is made similarly to budder but comes in a thin, brittle and translucent form; there’s also “wax” or “crumble,” which confusingly is not waxy but is more like a powdery or grainy substance; and “keef” or “kief,” which is powdery in nature and derived from the most potent parts of the cannabis plant. It is similar to hashish.

The names change regularly and can vary by guide or from person to person. It is best to ask what a term means from an open and curious place than to act as if you know all the terminology.

Many concentrates are vaporized and inhaled. Vaporizing is different than smoking, as vaporizing heats the concentrate until it becomes a gas, which is inhaled. Smoking involves burning the compound to produce an inhaled gas.

Many who vaporize concentrates call it “dabbing.” This refers to the dab of concentrate to heat, vaporize and inhale. Another way to vaporize cannabis concentrates is to use a vape pen. Vape pens are sometimes also called dab pens, depending on the local terms.

Cannabis and Adolescents

One of the reasons why young people are drawn to these sorts of products is that vaping or dabbing the concentrated form makes it easier to hide cannabis use. Vaping cannabis does not create the typical smell associated with weed.

A 2021 systematic review found that past-year cannabis vaping nearly doubled from 2017 to 2020 in adolescents - jumping from 7.2% to 13.2%. A more recent study in five northeastern U.S. states found that 12.8% of adolescents vaped cannabis in the past 30 days, a more narrow time frame that suggests potential increases in use. In addition, a 2020 study found that one-third of adolescents who vape do so with cannabis concentrates.

Cannabis use by adolescents is scary because it can alter the way their brains develop. Research shows that the brains of adolescents who use cannabis are less primed to change in response to new experiences, which is a key part of adolescent development. Adolescents who use cannabis are also more likely to experience symptoms of schizophrenia, struggle more in school and engage in other risky behaviors.

The risks of cannabis use are even greater with concentrates because of the high levels of THC. This is true for both adolescents and adults, with greater risk for symptoms of schizophrenia such as hallucinations and delusions, mental health symptoms and more severe cannabis use.

The best analogy is with another drug – alcohol. Most people know that a 12-ounce beer is much less potent than 12 ounces of vodka. Cannabis in smoked form is closer to the beer, while a concentrate is more like the vodka. Neither is safe for an adolescent, but one is even more dangerous.

These dangers make early conversations with kids about cannabis and cannabis concentrates critically important. Research consistently shows that expressing disapproval of drug use makes adolescents less likely to start drug use.

Start these conversations early – ideally before middle school. You can find some helpful online resources to guide the conversation.

While these conversations can be uncomfortable, and you can look like the out-of-touch adult, they can be a major step toward preventing adolescents from using cannabis and other drugs.

Does Netflix Trivialize Pain?

By Pat Anson, PNN Editor

Movies and TV shows have long been criticized for the way they depict women, minorities and religions -- either through sensationalism, stereotyped portrayals, or simply omission.

A new analysis of popular programs that aired on Netflix suggests that physical pain is also being ignored, trivialized, or presented in misleading ways.

Researchers in Canada and the UK looked at over a dozen movies and TV series that featured teenage characters. They found that the teens’ pain was almost always the result of violence or accidents – not common medical conditions such as migraine or menstruation. The characters often had minimal reactions to their own pain and observers had “an overwhelming lack of empathy” for them.   

“If we’re not showing the types of pain that adolescents might typically experience like back pain and menstrual pain, then we’re trivializing pain. We’re not doing a great job of enabling them to think about how to manage pain, how to talk about pain and how to show empathy when other people experience pain,” said lead author Abbie Jordan, PhD, a lecturer in the Department of Psychology and Centre for Pain Research at The University of Bath.

“This research matters because if every film and television series shows a boy being a ‘tough guy’ when they experience pain and a girl as a ‘damsel in distress’ in need of saving, they might think they have to be like that in real life. This depiction reinforces old-fashioned ideas about gender and is misleading."

Jordan and her colleagues watched programs such as Sex Education, Stranger Things and Enola Holmes, and found that viewers were exposed to an average of 10 incidents of pain every hour.

The two Netflix shows with the highest number of painful incidents were Outer Banks, a series about teens searching for a hidden treasure, and Spiderman: Homecoming, a movie about a young Peter Parker facing off against a new villain.

Violence (57%) was the most likely cause of pain on the Netflix shows, followed by everyday pain such as headaches (21%) and pain stemming from injuries (20%). Chronic pain or pain resulting from medical procedures were depicted less than one percent of the time.

“‘OUTER BANKS”

Researchers say the Netflix shows often reinforced sexist and patriarchal stereotypes. Boy characters were more likely to experience pain (77%) than girls (23%), and they were also more likely to be criticized or laughed at by other characters. Boys were often portrayed as heroic figures coming to the rescue, while girls were more emotional when reacting to pain.   

The plots and characters are all fictional, but researchers say adolescents watching at home are likely to mirror the behavior themselves.  

“Media is one of the most powerful engines of influence on children’s development and could be harnessed to address pain and suffering in the world. Stories matter. Fictional stories can matter more in some cases than real-life stories. So, let's create stories to reflect the world we want to see: A humane, diverse, inclusive, equitable, compassionate, and caring world,” says co-author Melanie Noel, PhD, an Associate Professor of Clinical Psychology at the University of Calgary.

“I want Netflix to take this seriously and get excited and inspired to directly influence millions of children around the world. They have a monumental opportunity to influence the compassion and humanity we see in our children and our future world.”

The study findings, published in the journal PAIN, echo a previous study that showed pain was trivialized for even younger children (aged 4-6 years). That study also showed that chronic pain in childhood and adolescence was rarely portrayed in popular media.

Is Cannabis Harmful During Pregnancy and Adolescence?

By Hilary Marusak, Wayne State University

Cannabis is a widely used psychoactive drug worldwide, and its popularity is growing: The U.S. market for recreational cannabis sales could surpass $72 billion by 2023.

As of early 2023, 21 U.S. states and the District of Columbia have legalized cannabis for recreational use for people age 21 and up, while 39 states plus the District of Columbia have legalized it for medical use.

The growing wave of legalization and the dramatic increase in cannabis potency over the past two decades have raised concerns among scientists and public health experts about the potential health effects of cannabis use during pregnancy and other vulnerable periods of development, such as the teen years.

I am a developmental neuroscientist specializing in studying what’s known as the endocannabinoid system. This is an evolutionarily ancient system found in humans and other vertebrates that produces natural cannabinoids such as THC and CBD.

Cannabis and its constituents interact with the body’s endocannabinoid system to product their effects. THC and CBD are the most commonly known cannabis extracts and can be synthesized in a lab. My lab also studies the risks versus potential therapeutic value of cannabis and cannabinoids.

Potential Health Risks

People often assume there’s no risk when using cannabis or cannabinoids during vulnerable periods of life, but they’re basing that on little to no data. Our research and that of others suggests that cannabis use during pregnancy and adolescence can present myriad health risks the public should be aware of.

Data shows that many people who use cannabis continue to do so during pregnancy. But there are health risks. More and more pregnant people are using cannabis today compared with a decade ago, with some studies showing that nearly 1 in 4 pregnant adolescents report that they use cannabis.

Many cannabis-using people may have not known they were pregnant and stopped using when they found out. Others report using cannabis for its touted ability to ease pregnancy-related symptoms, like nausea and anxiety. However, studies do not yet confirm those health claims. What’s more, the potential harms are often downplayed by pro-cannabis marketing and messaging by dispensaries, advocacy groups and even midwives or doulas.

In addition, physicians and other health care providers often are not knowledgeable enough or don’t feel well equipped to discuss the potential risks and benefits of cannabis with their patients, including during pregnancy.

While research shows that most people who are pregnant perceive little to no risk in using cannabis during pregnancy, the data show there is clear cause for concern. Indeed, a growing number of studies link prenatal cannabis exposure to greater risk of preterm birth, lower birth weight and psychiatric and behavioral problems in children. These include, for example, difficulties with attention, thought, social problems, anxiety and depression.

Cannabis and Brain Development

When cannabis is inhaled, consumed orally or taken in through other routes, it can easily cross through the placenta and deposit in the fetal brain, disrupting brain development.

A recent study from my lab, led by medical student Mohammed Faraj, found that cannabis use during pregnancy can shape the developing brain in ways that are detectable even a decade later.

We used data from the National Institutes of Health Adolescent Brain Cognitive Development Study, which is the largest long-term study of brain development and child and adolescent health in the U.S. It has followed more than 10,000 children and their families from age 9-10 over a 10-year period.

Through that analysis, we linked prenatal cannabis exposure to alterations in functional brain networks in 9- and 10-year-old children. In particular, prenatal cannabis exposure appeared to disrupt the communication between brain networks involved in attentional control, which may explain why children who were exposed to cannabis in utero may develop difficulties with attention or other behavioral issues or mental disorders as they develop.

While alcohol abuse has steadily declined among adolescents since 2000 in the U.S., cannabis use shows the opposite pattern: It increased by 245% during that same period.

Data reported in 2022 from the Monitoring the Future survey of over 50,000 students in the U.S. found that nearly one-third of 12th grade students reported using cannabis in the past year, including cannabis vaping. Yet only about 1 in 4 12th grade students perceive great harm in using cannabis regularly. This suggests that many teens use cannabis, but very few consider it to have potential negative effects.

Research shows that the adolescent brain is primed to engage in high-risk behaviors such as experimenting with cannabis and other substances. Unfortunately, owing to ongoing brain development, the adolescent brain is also particularly susceptible to the effects of cannabis and other substances. Indeed, many neuroscientists now agree that the brain continues to develop well into the second and even third decade of life.

In line with this vulnerability, research shows that, relative to those who did not use cannabis during adolescence, those who started using it during adolescence are at increased risk of developing depression, suicidal ideation, psychosis and reductions in IQ during adolescence and adulthood. Neuroimaging studies also show residual effects of adolescent cannabis use on brain functioning, even later during adulthood.

‘No Amount Is Safe’

Despite common misconceptions that cannabis is “all natural” and safe to use during pregnancy or adolescence, the data suggests there are real risks. In fact, in 2019, the U.S. surgeon general issued an advisory against the use of cannabis during pregnancy and adolescence, stating that “no amount … is known to be safe.”

Cannabis may be harmful to the developing brain because it disrupts the developing endocannabinoid system, which plays a critical role in shaping brain development from conception and into adulthood. This includes neural circuits involved in learning, memory, decision-making and emotion regulation.

While much of this research has focused on cannabis use, there is also other research that comes to similar conclusions for THC and CBD in other forms. In fact, although CBD is widely available as an unregulated supplement, we researchers know almost nothing about its effects on the developing brain. Of note, these harms apply not only to smoking, but also to ingesting, vaping or other ways of consuming cannabis or its extracts.

In my view, it’s important that consumers know these risks and recognize that not everything claimed in a label is backed by science. So before you pick up that edible or vape pen for stress, anxiety, or sleep or pain control, it’s important to talk to a health care provider about potential risks – especially if you are or could be pregnant or are a teen or young adult.

Overdose Deaths Double for Teenagers Amid Fentanyl Surge

By Pat Anson, PNN Editor

Drug deaths among U.S. teenagers have risen sharply in the last two years, according to a new study that found the number of fatal overdoses doubled for adolescents aged 14 to 18 years.

In 2019, there were 492 drug deaths among adolescents. In 2021, there were an estimated 1,146 fatal overdoses, a 133% increase.

The vast majority of adolescent drug deaths last year involved illicit fentanyl (77%), followed by benzodiazepines (13%), methamphetamines (10%) and cocaine (7%). Less than 6% of the overdoses among teens involved a prescription opioid.

The study findings, reported in the journal JAMA, reflect what is happening in the overall U.S. population, with drug overdoses rising to record levels. They also mark the reversal of a decade long trend of fewer overdose deaths among teens, which coincided with declining rates of illicit drug use.

Researchers say adolescents may be unaware or naive about the risks posed by fentanyl, a synthetic opioid up to 100 times more potent than morphine and 50 times stronger than heroin. In a prescription, fentanyl plays a valuable role in treating severe pain, but as a street drug it can be deadly

“Beginning in 2020, adolescents experienced a greater relative increase in overdose mortality than the overall population, attributable in large part to fatalities involving fentanyls,” lead author Joseph Friedman, MPH, University of California, Los Angeles, reported in the journal JAMA.

“In the context of decreasing adolescent drug use rates nationally, these shifts suggest heightened risk from illicit fentanyls, which have variable and high potency. Since 2015, fentanyls have been increasingly added to counterfeit pills resembling prescription opioids, benzodiazepines, and other drugs, which adolescents may not identify as dangerous and which may be playing a key role in these shifts.”

U.S. Adolescent Overdose Deaths

SOURCE: jama

Friedman and his colleagues found the highest overdose rates among Native American, Alaska Native and Latino adolescents, reflecting what they called a “wider pattern of increasing racial and ethnic inequalities” in drug deaths.

Fentanyl is even killing kids who have not reached their teenage years. In California, a boy was recently arrested and charged with murder in the death of 12-year-old Dalilah Guerrero. The 16-year-old suspect allegedly sold a counterfeit pill made with fentanyl to the girl, who overdosed after crushing and snorting the tablet at a party in San Jose.

The spike in adolescent drug deaths comes even as substance abuse by teens fell to record lows. An annual survey by the University of Michigan found significant declines in all types of drug use by adolescents in 2021, with the use of prescription opioids falling to the lowest level in nearly two decades.    

DEA Warns of Fentanyl Mass Overdoses

Public health experts and law enforcement agencies are growing increasingly alarmed by the rising number of fentanyl overdoses. Last week, the DEA warned of a nationwide spike in fentanyl-related mass overdose events, in which three or more overdoses occur in the same location.

In the past three months, at least seven mass overdoses were reported in Florida, Texas, Colorado, Nebraska, Missouri and Washington, DC, resulting in 29 deaths. Three people died in a hotel room in Cortez, Colorado after ingesting what that they thought were 30mg oxycodone pills, but were actually counterfeit pills containing fentanyl.

“Tragic events like these are being driven by fentanyl. Fentanyl is highly-addictive, found in all 50 states, and drug traffickers are increasingly mixing it with other types of drugs — in powder and pill form — in an effort to drive addiction and attract repeat buyers,” DEA Administrator Anne Milgram said in a letter to federal, state and local law enforcement agencies. 

“We recommend that the members of your offices assume that all drugs encountered during enforcement activities now contain fentanyl. Given fentanyl’s extreme toxicity and the increases we are seeing in the distribution of polydrug substances containing fentanyl, please take all the precautions you would take when handling fentanyl whenever you interdict any illicit substance.”

A recent study by the National Institute of Drug Abuse estimated that over 9.6 million counterfeit pills containing fentanyl were seized by U.S. law enforcement agencies last year.

Illicit Drug Use by Teens Fell Significantly in 2021

By Pat Anson, PNN Editor

Substance abuse by U.S. teenagers declined significantly this year, according to the results of a new national survey that found the use of prescription opioids by adolescents fell to the lowest level in nearly two decades.

Illicit drug use by 10th graders fell by nearly 12 percent in 2021, and by about 5% for eighth and 12th graders. The findings represent the largest one-year decline in illicit drug use by teens since the Monitoring the Future survey began in 1975.

The study by University of Michigan researchers found that teenagers reported increased feelings of boredom, anxiety, depression and loneliness in 2021 – no doubt fueled by pandemic-related fears and isolation. But unlike their adult counterparts, young people overall did not increase their use of marijuana, alcohol and other drugs.

“We have never seen such dramatic decreases in drug use among teens in just a one-year period. These data are unprecedented and highlight one unexpected potential consequence of the COVID-19 pandemic, which caused seismic shifts in the day-to-day lives of adolescents,” Nora Volkow, MD, Director of the National Institute on Drug Abuse, said in a statement.

“Moving forward, it will be crucial to identify the pivotal elements of this past year that contributed to decreased drug use – whether related to drug availability, family involvement, differences in peer pressure, or other factors – and harness them to inform future prevention efforts.”

The Monitoring the Future survey is given annually to students in eighth, 10th and 12th grades, who self-report their drug use behaviors and attitudes. The results from this year’s survey were collected from February through June 2021. Over 32,000 students enrolled in 319 public and private schools in the U.S. participated, with some taking the survey at home and others while at school.

The percentage of students who reported using any illicit drug other than marijuana within the past year decreased significantly. Among 12th graders, for example, 7.2% reported using an illicit drug in 2021, compared to 11.4% in 2020.

Decreases were also reported in the use of alcohol by 12th graders (46.5% in 2021 vs. 55.3% in 2020) and in marijuana (30.5% in 2021 vs. 35.2% in 2020).

Significant declines in use were also reported by students in 2021 for a wide range of drugs, including cocaine, heroin, hallucinogens, cigarettes and nonmedical use of amphetamines, tranquilizers, and prescription opioids.

The decline in drug use by teens is not a one-year fluke and is part of a long running trend. For example, the use of Vicodin by 12th graders has fallen by nearly 92 percent since its peak in 2003. The use of OxyContin has declined by 83% since its peak in 2005.   

MONITORING THE FUTURE SURVEY

“In addition to looking at these significant one-year declines in substance use among young people, the real benefit of the Monitoring the Future survey is our unique ability to track changes over time, and over the course of history,” said Richard Miech, PhD, who led the Monitoring the Future study at the University of Michigan. “We knew that this year’s data would illuminate how the COVID-19 pandemic may have impacted substance use among young people.”

Not all the news is good. The researchers found that adolescents who suffered severe stress, anxiety or depression due to the pandemic, experienced financial hardship, or whose parents used drugs were most likely to use drugs themselves.

Other studies have found that adults who regularly use recreational drugs increased their drug usage during the pandemic. A new study of alcohol sales in 16 U.S. states found a major increase in wine and liquor sales in the first few months of the pandemic, by as much as 20 to 40 percent in some states.

Another recent study found that opioid prescribing briefly increased in the early stages of the pandemic, as patients postponed corrective procedures and it became harder to obtain non-opioid therapies for pain such as massage and physical therapy. Opioid prescribing returned to previous levels after a few months.   

The CDC announced last month that the U.S. has seen over 100,000 drug deaths in the 12-month period ending in May, 2021. The record-high spike in overdoses is thought to be primarily a result of pandemic lockdowns and the continuing spread of illicit fentanyl.
