"Both groups of rats became addicted at the same rate."

Sure, that's plausible. Heroin is highly addictive.

But, as I said in my post, that has nothing to do with the gateway theory. As correctly stated by the author, it is "the claim that marijuana use leads to harder drugs". The theory says that pot users are more likely to try other drugs, including harder drugs.

And if a higher percentage of pot smokers (vs. carrot eaters or milk drinkers) try harder drugs, that will naturally result in a higher number addicted, even if the addiction rate is the same.

The theory says that pot users are more likely to try other drugs, including harder drugs.

Then any implication that using pot makes you more likely to want to try harder drugs is misinformation. The inclination is already there, and the pot use is simply an indicator.

And yet this study was trumpeted as proof of the gateway theory. It proved no such thing, as the heretofore un-reported details show.
