From time to time we get some flack for pointing out that as a “recreational” substance, marijuana is safer than alcohol. Anyone who doubts that claim might want to look at this new study from The Lancet, one of the world’s top medical journals.

Researchers reviewed information on deaths in three major Russian cities from 1990 to 2001 and questioned family members about the decedents’ alcohol use, reporting the astonishing finding that “in several recent years, alcohol was a cause of more than half of all Russian deaths at ages 15-54 years.” Causes of death that were greatly increased by heavy alcohol use included accidents, violence, alcohol poisoning, and several types of cancer.

We’ve said it before, but we’ll keep saying it: No drug is 100% harmless, but marijuana simply does not cause anything near the wreckage that alcohol causes, even in very heavy users.

In the May issue of Current Opinion in Psychiatry, two noted researchers weigh in on the marijuana debate with an article titled, “The Challenges in Developing a Rational Cannabis Policy.”

Australian Wayne Hall and American Michael Lynskey urge that international treaties be rewritten to allow nations more freedom to experiment with policy changes, and more research aimed at weighing the costs and benefits of prohibition. Along the way, they make a number of noteworthy observations, including this:

The public health impact of contemporary patterns of cannabis use is modest by comparison with those of other illicit drugs (such as the opioids) or with tobacco or alcohol. In the case of illicit drugs, this reflects the absence of fatal overdose risk from cannabis. In the case of alcohol, it reflects the much lower risks of death from cannabis-impaired than alcohol-impaired driving, fewer adverse effects on health and lower rates of regular cannabis use to intoxication.

 Would that U.S. policies were based on such a calm, rational assessment of the facts  

MPP’s Bruce Mirken will appear on CNN’s “Anderson Cooper 360″ tonight to add a little rationality to the latest pronouncement regarding rising THC levels in marijuana from the National Institute on Drug Abuse-funded Marijuana Potency Project.

Drug warriors love to exaggerate small increases in marijuana potency over time and make vague proclamations linking those increases to increases in marijuana’s potential danger, even though no credible research supports such a connection. Of course, if they were truly concerned about the potential danger of higher potency marijuana, then they should favor regulating the drug and requiring manufacturers to label the product’s potency, just as we do with alcohol.

The show is scheduled to air tonight at 10 p.m. EST, but the hysteria surrounding one of the drug warriors’ favorite imaginary fears is sure to last much longer.

The question of why some kids start using alcohol, cigarettes, marijuana, and other drugs at a young age remains a source of controversy. How much of a role do genes play? The environment — peers, parents, educational efforts? What about the “gateway theory,” the idea that one drug — marijuana is the most likely to be blamed — leads to use of others?

A new study of twins recently published online by the journal Drug and Alcohol Dependence suggests that genes may play a large role, but to some degree every drug is a gateway drug. [Read more →]

The journal Clinical EEG and Neuroscience has just published a review of the data on the effects of substance use on the developing brains of adolescents. The unmistakable conclusion: While heavy substance use of any kind is a really bad idea for teens, the damaging effects of alcohol are clearly worse than marijuana. The researchers write:

Abnormalities have been seen in brain structure volume, white matter quality, and activation to cognitive tasks, even in youth with as little as 1-2 years of heavy drinking and consumption levels of 20 drinks per month, especially if >4-5 drinks are consumed on a single occasion. Heavy marijuana users show some subtle anomalies too, but generally not the same degree of divergence from demographically similar non-using adolescents.

Strikingly, in a couple of studies, the damaging effects of binge drinking were less if the drinker also used marijuana, suggesting — though not proving — a possible protective effect in some circumstances. That’s actually no shock, as the U.S. government holds a patent  on cannabinoids — marijuana’s unique, active components — as neuroprotectants (substances that protect nerve and brain cells from damage).

From time to time we hear dubious claims that marijuana is carcinogenic, even though there’s abundant evidence that marijuana’s active components are actually pretty potent anti-cancer drugs.

That alcohol is a far more serious cancer risk is underlined by this Washington Post story about a massive new British study  – involving 1.3 million women — indicating that even a single drink per day can increase the risk of many types of cancers. The researchers estimate that booze could account for as much as 5 percent of all cancers among women in the U.S.

No, that does not mean we should arrest and jail people for drinking. It does mean that discussions of the health risks of marijuana are often wildly out of balance, skewed by the stigma attached to an illegal substance.

     California state Assemblyman Tom Ammiano (D-San Francisco) today announced the introduction of legislation to tax and regulate marijuana in a manner similar to alcoholic beverages. The bill, the first of its kind ever introduced in California, would create a regulatory structure similar to that used for beer, wine, and liquor, permitting taxed sales to adults while barring sales to or possession by those under 21.

       Estimates based on federal government statistics have shown marijuana to be California’s top cash crop, valued at approximately $14 billion in 2006 — nearly twice the combined value of the state’s number two and three crops, vegetables ($5.7 billion) and grapes ($2.6 billion) — in spite of massive “eradication” efforts that wipe out an average of nearly 36,000 cultivation sites per year without making a dent in this underground industry.

Last night, CNBC aired its much-touted documentary, “Marijuana Inc.” It was a decidedly mixed bag.

It was a portrait of an industry that is huge and thriving, despite the energetic efforts of assorted law enforcement agencies to “eradicate” it. No sane person could watch the program and come away thinking that present government efforts to curb marijuana production or use are working.  With California’s Mendocino County as the focus, the crashing failure of the war on marijuana was on vivid display.

What was missing was context. [Read more →]
