Okay, I’m a bit behind in my reading, but a study published last month in the journal Addiction casts an interesting light on the so-called “gateway effect” — the idea that use of one drug, usually marijuana, somehow leads to use of others.

Gateway associations have regularly been found between tobacco and marijuana: Young people who use one are pretty consistently more likely to use the other as well. But does tobacco cause kids to smoke marijuana, marijuana cause kids to use tobacco, or are both tendencies the result of other factors entirely?

The new study, by researchers in Queensland, Australia, and St. Louis, suggests that genetics, not the effects of any particular drug, are at the heart of these associations. [Read more →]

On Saturday, New Bedford Standard-Times columnist Jack Spillane weighed with an eminently sensible and amusing take on the opposition to Question 2 , the marijuana decriminalization initiative on the November ballot in Massachusetts. He quotes some funny/scary dialogue from the press conference held by prosecutors and other opponents that managed to escape the notice of other reporters. The silliness begins with Bristol County District Attorney Sam Sutter:

And “I don’t want to hear,” he said, those “specious” and “bogus” arguments that marijuana is like alcohol. Alcohol, he informed the media event, can have health benefits. You know, like wine, he said.

And tobacco? Why, that takes a long time to do damage, he informed.

Ah, Sam, say it ain’t so.

Not to be outdone, Fall River Mayor Bob Correia trotted out the time-tested “gateway” argument.

“Marijuana,” he said, is “the one they start our children off with!” [Read more →]

In a refreshing, though no doubt unintended, bit of honesty, the White House Office of National Drug Control Policy seems to be acknowledging that alcohol is the true “gateway drug.” In a June 26 post on ONDCP’s blog, the federal drug warriors proclaim, “More than 67 percent of young people who start drinking before the age of 15 will try an illicit drug. Children who drink are over 7 times more likely to use any illicit drug, are over 22 times more likely to use marijuana, and 50 times more likely to use cocaine than children who never drink.”

ONDCP regularly uses similar correlations between marijuana and use of other drugs to argue that marijuana is a “gateway drug” that must be kept illegal for adults, but they make no such argument for banning booze. The truth — which the folks at ONDCP know  but will never say — is that neither alcohol nor marijuana causes people to try other drugs. People inclined to try mood-altering substances simply start with what’s most easily available.
