Oh, and on the subject of gateways, keep this in mind:
“People who enjoy the effects of marijuana are, logically, more likely to be willing to try other mood-altering drugs than are people who are not willing to try marijuana or who dislike its effects. In other words, many of the factors associated with a willingness to use marijuana are, presumably, the same as those associated with a willingness to use other illicit drugs. [...] There is no evidence that marijuana serves as a stepping stone on the basis of its particular physiological effect. One might argue that marijuana is generally used before other illicit mood-altering drugs, in part, because its effects are milder; in that case, marijuana is a stepping stone only in the same sense as taking a small dose of a particular drug and then increasing that dose over time is a stepping stone to increased drug use.” - “Marijuana and Medicine: Assessing the Science Base”, Institute of Medicine, National Academy of Sciences
So its a gateway. Thanks, since observed histories of many of my wife’s patients confirm that.
