Interestingly enough, I just did an
essay on this. One of my best sources was Paul Hager's "
Marijuana Myths" which I found at
http://www.marijuana-hemp.com/cin/facts/marmyt1.shtml.
If I may
invoke fair use:
This is one of the more persistent myths. A real world example of what happens when marijuana is readily available can be found in Holland. The Dutch partially legalized marijuana in the 1970s. Since then, hard drug use -- heroin and cocaine -- have declined substantially. If marijuana really were a gateway drug, one would have expected use of hard drugs to have gone up, not down. This apparent "negative gateway" effect has also been observed in the United States. Studies done in the early 1970s showed a negative correlation between use of marijuana and use of alcohol. A 1993 Rand Corporation study that compared drug use in states that had decriminalized marijuana versus those that had not, found that where marijuana was more available -- the states that had decriminalized -- hard drug abuse as measured by emergency room episodes decreased. In short, what science and actual experience tell us is that marijuana tends to substitute for the much more dangerous hard drugs like alcohol, cocaine, and heroin.
That's
pretty darn interesting and just about
debases the whole gateway drug argument. When you look at the "marijuana is bad!" argument, the only thing that it had going for it was the gateway drug defense. It's been shown time and time again that the negative aspects of marijuana are
infinitesimal, or at least, less that some
legal drugs.
Hardlinking and bolding by me.
