But it is not a drug with great dependence potential. Of seventy million Americans who have tried cannabis, only about 2 million are current daily users. In different cultures, cannabis use is linked to the use of different drugs. There is nothing about cannabis pharmacology that would lead people to use any other drug. In fact, most cannabis users never do.
Doctors are afraid.
In the U.S., they can't prescribe cannabis at all. There are no legal supplies. I am more in favor of cannabis decriminalization. Some people develop problems controlling cannabis use, but most get out of trouble by themselves later. There is no real way to accurately measure how many people this happens to.
