Pot

Two Jordanian nationals were arrested trying to break into a U.S. Marine base in Virginia. A local report stating that one of the two individuals was a Jordanian foreign national who “recently crossed the southern border into the U.S.” and also that one of them is on the U.S. terrorist watch list has, strangely, not been clarified or even addressed.

Pot

This is a bit long, cut out of an interview with Dr. Bertha Madras, an established marijuana researcher. But there are some important ideas--as well as some admittedly strange, subjective elements--that most people would see as cautionary. The pivotal point is the suggestion to reduce marijuana from a Schedule I to a Schedule III drug.

Last week media outlets reported that the Biden administration is moving to reclassify marijuana as a less dangerous Schedule III drug—on par with anabolic steroids and Tylenol with codeine—which would provide tax benefits and a financial boon to the pot industry. A crucial change is that Schedule III drugs are easier to bring across state lines--and thus sidestep state regulation.

Bertha Madras thinks this would be a colossal mistake. Ms. Madras, 81, is a psychobiology professor at Harvard Medical School and one of the foremost experts on marijuana. “It’s a political decision, not a scientific one,” she says. “And it’s a tragic one.” In 2024, that is a countercultural view.

A 2022 survey sponsored by the National Institutes of Health found that 28.8% of Americans aged 19 to 30 had used marijuana in the preceding 30 days—more than three times as many as smoked cigarettes. Among those 35 to 50, 17.3% had used weed in the previous month, versus 12.2% for cigarettes.

In 2015 the World Health Organization asked 
Madras to do a detailed review of cannabis and its medical uses. The 41-page report documented scant evidence of marijuana’s medicinal benefits and reams of research on its harms, from cognitive impairment and psychosis to car accidents.

She says, the “addiction potential of marijuana is as high or higher than some other drugs,” especially for young people. About 30% of those who use cannabis have some degree of a use disorder. By comparison, only 13.5% of drinkers are estimated to be dependent on alcohol. Sure, alcohol can also cause harm if consumed in excess. But Ms. Madras sees several other distinctions.

One or two drinks will cause only mild inebriation, while “most people who use marijuana are using it to become intoxicated and to get high.” Academic outcomes and college completion rates for young people are much worse for those who use marijuana than for those who drink, though there’s a caveat: “It’s still a chicken and egg whether or not these kids are more susceptible to the effects of marijuana or they’re using marijuana for self-medication or what have you.”

Marijuana and alcohol both interfere with driving, but with the former there are no medical “cutoff points” to determine whether it’s safe to get behind the wheel. As a result, prohibitions against driving under the influence are less likely to be enforced for people who are high. States where marijuana is legal have seen increases in car accidents.

"My lab showed unequivocally that blood levels and brain levels don’t correspond at all—that brain levels are much higher than blood levels. They’re two to three times higher, and they persist once blood levels go way down.” Even if people quit using pot, “it can persist in their brain for a while.”

Levels of THC—the main psychoactive ingredient in pot—are four or more times as high as they were 30 years ago.

There’s mounting evidence that cannabis can cause schizophrenia. A large-scale study last year that examined health histories of some 6.9 million Danes between 1972 and 2021 estimated that up to 30% of young men’s schizophrenia diagnoses could have been prevented had they not become dependent on pot.

Another cause for concern, she notes, is that more pregnant women are using pot, which has been linked to increased preterm deliveries, admissions of newborns into neonatal intensive care units, lower birth weights and smaller head circumferences. THC crosses the placenta and mimics molecules that our bodies naturally produce that regulate brain development.

“What happens when you examine kids who have been exposed during that critical period?” Ms. Madras asks. During adolescence, she answers, they show an increased incidence of aggressive behavior, cognitive dysfunction, and symptoms of ADHD and obsessive-compulsive disorders. They have reduced white and gray matter.

What about medicinal benefits? Ms. Madras says she has reviewed “every single case of therapeutic indication for marijuana—and there are over 100 now that people have claimed—and I frankly found that the only one that came close to having some evidence from randomized controlled trials was the neuropathic pain studies.”

Instead of bankrolling ballot initiatives to legalize pot, she says, George Soros and other wealthy donors who “catalyzed this whole movement” should be funding rigorous research: “If these folks, these billionaires, had just taken that money and put it into clinical trials, I would have been at peace.”

It’s a travesty, Ms. Madras adds, that the “FDA has decided that they’re going to listen to that movement rather than to what the science says.”

There is plenty to concern us here. The big question is the quality of research. One element limiting marijuana's commercial success is the fragmentation of the industry. There is no consistency of product--from day to day, producer to producer, facility to facility--so a consistent user base has not developed. Think Sam Adams or Lowenbrau where the customer never knew what taste he was buying. While that is a problem for manufacturers, it is a nightmare for research. There is simply no way to assess the drug in the world because there is no prototypical plant. Second, there is a very strange concentration of popular social pressure at work. Why do these radical political groups have such uniform support for these drugs? It's like seeing the Climate Child at the pro-Palestine demonstrations; that is simply peculiar.
And if a researcher like this has reservations, enthusiastic fast-tracking seems peculiar as well.
