Medical Cannabis No Help to Lobsters
/By Pat Anson, PNN Editor
Do lobsters feel pain when they’re boiled alive?
Seafood lovers, cooks, academics, animal rights activists and even governments have debated that question for years, with the general consensus being that they do. Lobsters, crabs and other crustaceans will often writhe in pain and try to escape when dropped into a pot of scalding hot water. The practice is considered so cruel that Switzerland and New Zealand made it illegal to boil a live lobster.
Some cooks try to ease the lobsters’ pain by stunning them with a jolt of electricity or putting them on ice to dull their senses before cooking them. In 2018, a restaurant owner in Maine even blew marijuana smoke on a lobster named Roscoe, who reportedly grew so mellow he never wielded his claws as weapons again while in captivity.
We’ll never know the long-term effect of getting a lobster stoned because Roscoe was returned to the ocean as a thank you for his service. Good for him.
Which brings us to a bizarre study recently completed by scientists at the University of California San Diego and the Scripps Research Institute, who decided to replicate the Roscoe experiment in a lab.
"The 2018 minor media storm about a restaurant owner proposing to expose lobsters to cannabis smoke really was the starting point. There were several testable claims made and I realized we could test those claims. So we did," lead author Michael Taffe, PhD, an adjunct professor at Scripps Research told IFLScience.
Taffe and his colleagues purchased ten Maine lobsters at a local supermarket, fed them a last meal of frozen krill and fish flakes, and placed them in an aerated vapor chamber.
For the next 30 to 60 minutes, the lobsters were exposed to vapor rich in tetrahydrocannabinol (THC), the psychoactive ingredient in cannabis.
Afterwards, some of the lobsters were “rapidly euthanized” with a kitchen shear and dissected, while others were immersed in hot water to see how they’d react.
Detectable levels of THC were found in the muscles and organs of the euthanized lobsters, so from that standpoint the experiment was a success. But the THC apparently had little effect on the remaining live lobsters, who displayed “distinct motor responses” and other signs of pain when put in hot water.
"The effect of vapor THC on this nociceptive (pain) behavior was very minimal. Statistically supported in one case, but of very small magnitude," said Taffe.
We’ll leave it to readers to decide whether a study like this is humane, worthwhile or even makes sense. But it is worth noting that taxpayers helped pay for it.
The lobster cannabis study was supported by grants from the U.S. Public Health Service. Researchers were careful to note that federal funding was not directly used to purchase the lobsters. That money came from La Jolla Alcohol Research, a private company that is developing vapor inhalation technologies. According to GovTribe, La Jolla Alcohol Research has received about $3 million in federal funding in recent years, most of it coming from the National Institute on Drug Abuse.
