Margaret Wente

I wrote a letter to Margaret Wente because of this. http://www.rbcinvest.theglobeandmail.com/servlet/ArticleNews/PEstory/LAC/20070626/COWENTE26/Headlines/headdex/headdexHealth/6/6/14/%3Cbr/%3E

Potent pot is more is more Drug Czar myth than reality. http://www.slate.com/id/2074151 Only the Independent bought in and the Guardian took care of them. http://www.guardian.co.uk/drugs/Story/0,,2041749,00.html

However, even if one assumes that potent pot is a reality it is certainly nothing to be concerned about. Indeed, saying that potent pot is reason for keeping marijuana illegal is akin to saying that alcohol should be banned because gin has higher alcohol content than beer. It makes no sense. The pharmacological affects of consuming 1 “chemically supercharged” joint, as various US attorneys like to say, versus x number of “dad’s joints” would be no different if the amount of THC consumed is the same. As for consumption, just as people do not drink the same volume of gin as beer, the higher the THC level in pot the less people consume. Hence, ironically more potent pot may be a welcome development. After all, one of the most prominent health effect related to marijuana, if not the most, is that it is usually smoked. The more potent the pot, the less people have to smoke to achieve the same high. Lester Grinspoon of Harvard Medical School concurs, so does Mitch Earleywine of the University of Southern California and so does UCLA’s Mark Kleiman.


Comparing marijuana strength through the years is "absurd," according to Lester Grinspoon, an emeritus professor at Harvard Medical School , who consults patients, many of them elderly, on using marijuana to relieve pain and nausea. "The whole issue on potency is a red herring," he said. "The more potent the pot, the less you use."Grinspoon said that studies have shown -- and his patients' experiences confirm -- that marijuana users smoke until they feel high -- or, as he prefers to say, "achieve symptom relief," -- and then stop, whether it took two hits or an entire joint. In this regard, today's higher-potency pot is no more "dangerous" than the bunk weed of yesteryear, he said.

unlike the speculative claims of increased danger, peer-reviewed scientific data show that higher potency marijuana reduces health risks. Just as with alcohol, people who smoke marijuana generally consume until they reach the desired effect, then stop. So people who smoke more potent marijuana smoke less – the same way most drinkers consume a smaller amount of vodka than they would of beer – and incur less chance of smoking-related damage to their lungs.

The original ONDCP "Facts" correspond with estimates from UCLA professor Mark Kleiman that marijuana has roughly tripled in potency. Kleiman also notes that there is no evidence at all that marijuana is getting kids more stoned than it used to. Writing on his own blog, Kleiman cites the respected annual University of Michigan study that asks respondents about levels of intoxication. Writes Kleiman: "The line for marijuana is flat as a pancake. Kids who get stoned today aren't getting any more stoned than their parents were. That ought to be the end of the argument." Kleiman points out that the average joint is now half its former size, so even if kids are smoking more powerful pot, they are smoking less of it. " 'Not your father's pot' is a great way to convince [boomer parents] to ignore their own experience, personal or
vicarious, and believe what they are told to believe."

All that being said, if potency is the concern, then it should be legalized. As Martha Hall Findlay has noted, the only way to regulate the potency of pot is to legalize it. Moreover, so long as the drug is illegal, producers will seek to increase potency. The higher the potency the smaller the package the smaller the package the less likely they will get caught.

By the way, I have question for you. If today’s marijuana is truly different in kind from “dads marijuana”, would it be ok to legalize “dad’s marijuana”, i.e., low potency pot?

While you are pondering just how to answer you can listen to helpless Barry MacKnight, chair of the Drug Abuse Committee for the Canadian Association of Police Chiefs duke it out over potent pot with the aforementioned Lester Grinspoon, a psychiatrist and Professor Emeritus at the Harvard Medical School.

Now, I really wanted to make this short, but you have made so many errors I really must continue.


Wente "It causes paranoia, aggressiveness and psychosis, and it sharply elevates the risk of schizophrenia."

Good god where to start? I think I will start with a US Department of Justice Study.


Marijuana and opiates temporarily inhibit violent behavior, but withdrawal from opiate addiction tends to exaggerate both aggressive and defensive responses to provocations.”

By point of contrast, this is what the same study said about alcohol, which is legal, and violence.


For at least the last several decades, alcohol drinking – by the perpetrator of a crime, the victim, both – has immediately preceded at least half of all violent events, including murders, in the sample studied by researchers.”

As for the purported link between marijuana and schizophrenia, I will let Maia Szalavitz at Stats at George Mason University put into context.

As for the purported link between marijuana and schizophrenia, I will let Maia Szalavitz at Stats at George Mason University put into context.

“A 40% increase in risk sounds scary, and this was the risk linked to trying marijuana once, not to heavy use. To epidemiologists a 40% increase is not especially noteworthy-- they usually don’t find risk factors worth worrying about until the number hits at least 200% and some major journals won’t publish studies unless the risk is 300 or even 400%. The marijuana paper did find that heavy use increased risk by 200-300%, but that’s hardly as sexy as try marijuana once, increase your risk of schizophrenia by nearly half!

By contrast, one study found that alcohol has been found to increase the risk of psychosis by 800% for men and 300% for women. Although this study was not a meta-analysis (which looks at multiple studies, as the marijuana research did), it certainly is worth citing to help readers get a sense of the magnitude of the risk in comparison with other drugs linked to psychosis.”

Next I will let her point out the elephant living room of those arguing for a causal link between marijuana and schizophrenia.

if marijuana produces what seems like such a large jump in risk for schizophrenia, have schizophrenia rates increased in line with marijuana use rates? A quick search of Medline shows that this is not the case-- in fact, as I noted here earlier, some experts think they may actually have fallen. Around the world, roughly 1% of the population has schizophrenia (and another 2% or so have other psychotic disorders), and this proportion doesn’t seem to change much. It is not correlated with population use rates of marijuana.

Since marijuana use rates have skyrocketed since the 1940’s and 50’s, going from single digit percentages of the population trying it to a peak of some 60% of high school seniors trying it in 1979 (stabilizing thereafter at roughly 50% of each high school class), we would expect to see this trend have some visible effect on the prevalence of schizophrenia and other psychoses.

When cigarette smoking barreled through the population, lung cancer rose in parallel; when smoking rates fell, lung cancer rates fell. This is not the case with marijuana and psychotic disorders; if it were, we’d be seeing an epidemic of psychosis.

By the why, how is Gordan Brown’s reefer war going. Has he convinced people such as Dr Iddon, chairman of the all-party parliamentary group on drugs misuse?

Dr Iddon, the chairman of the all-party parliamentary group on drugs misuse, said the study did not convince him it was time to return cannabis to class B. "I don't think the causal link has been proved. I think cannabis might - possibly for genetic reasons - trigger psychosis at an earlier age." The MP, who is also a member of the science and technology select committee, said there was a danger of criminalising "hundreds of thousands of young people" if the status of the drug was changed.
"If Gordon Brown changes the class of the drug, it won't be evidence-based but for political reasons," he said.
