ntoxicating part of marijuana). Nahas's generalizations from the petri dishes to human beings have been rejected by the scientific community as being invalid. Studies of actual human populations have failed to demonstrate that marijuana adversely affects the reproductive system. (Guideline #3, #6)A persistent myth about marijuana is that it is a gateway drug, leading to the use of harder drugs. The Dutch partially decriminalized marijuana in the 1970's since then the use of heroin and cocaine has sharply decreased. The opposite of this gateway affect is also present the United States.

It found that in states where marijuana was more available, hard drug abuse as measured by emergency room episodes decreased. What science and real experience tells us is that marijuana tends to substitute for much harder drugs like alcohol, cocaine, and heroin. (Guideline #3, #6)Another misconception is that marijuana is more dangerous than alcohol. Extremely high doses of cannibinoids cause death. Extremely high doses are the key words here. Scientists have concluded that the ratio of cannibinoids needed to get a person intoxicated (stoned) relative to the amount necessary to kill him is 1 to 40,000. That means that to overdose on marijuana you would need to consume 40,000 times as much as you would to get stoned. The ratio of alcohol varies between 1 in 4 and 1 in 10. Over 5,000 people die of alcohol overdoses each year, and no one has ever died from overdosing on pot.

Along with these myths comes the false belief that crime will increase if marijuana is legalized.
