A lot of pot users also tend to abuse alcohol.
My daughter has a bachelor’s degree in drug and alcohol counseling. She worked with all sorts of people including prisoners at a maximum security prison. She claims that people that abuse heroin, coke, meth, and other hard drugs, alcohol and tobacco are much easier to treat than pot users. The people that use heroin, alcohol and the other stuff generally realize they have a problem that they can’t control and seek help. Pot users seem to never think they have a problem even when it cost them their jobs, house, family or prison time. They are only getting treatment because they are forced into it.
