A new cannabinoid similar to THC was announced last month in Scientific Reports. Dubbed tetrahydrocannabiphorol, or THCP for short, it is being hailed as a “breakthrough discovery” that is 30 times stronger than THC, the chemical compound in cannabis that causes euphoria.

Discovered by a group of Italian researchers, THCP has been shown to have a high affinity for the cannabinoid receptor (CB1) in the brain. Cinzia Citti from the Institute of Nanotechnology told Medical Cannabis Network that THCP likely has pain relieving effects, but pharmacological studies are needed to confirm it.

“Once all pharmacological profile of THCP has been established, I can imagine that THCP-rich cannabis varieties will be developed in the future for specific pathologies,” Citti said.

THCP’s chemical structure makes it nearly optimal for activity at the CB1 receptor. Studies on mice showed that THCP has psychoactive effects at low doses, but research is required to confirm how strongly THCP acts on the human brain.

‘Potential Game Changer’

There is already great enthusiasm for THCP, as well as cannabidiphorol (CBDP), another newly identified cannabinoid compound.

Vice states that “it’s possible these chemicals could treat certain conditions better than their counterparts,” THC and CBD.

Leafly went even further, predicting the new cannabinoids could have “immense therapeutic implications,” with THCP being a “potential game changer.”

Looking beyond the media hype, there appears to be no critical consideration of what a cannabinoid 30 times more potent than THC might mean. THC Is known to have significant negative effects on the human body. The National Institute on Drug Abuse lists side effects such as impaired breathing, increased heart rate, and mental effects such as hallucinations, paranoia and schizophrenia.

Moreover, THC is addictive. Health Canada reports that 1 out of 10 people who use cannabis will develop an addiction. The addiction odds increase to 1 out of 2 for people who use cannabis daily.

In other words, is THCP going to be 30 times more additive than THC? Will it cause 30 times more cognitive impairment? A 30-fold increase in ER visits and hospital admissions?

If THCP acts much more strongly on the CB1 receptor, then it may not really be a good thing for cannabis users or public health. These questions may seem absurd, but potent synthetic cannabinoids like K2/Spice have been a public health concern for many years. THCP may also have unknown side effects.

The difference between THC and CBD comes down to one chemical bond, but their respective effects are quite different. The apparent similarities between THCP and THC cannot be used to draw conclusions about effects in humans, good or bad.  

At present, very little is known about THCP. As Live Science points out, "while THC offers some medicinal effects, including pain and nausea relief, no one knows if THCP has these qualities."

It would be nice if even just one media outlet had mentioned the THCP could have some of the same problems that THC does, and at far lower concentrations.
