alcohol, tobacco, and hard drugs, most people who use marijuana can stop taking it when they want, while experiencing only minor withdrawal symptoms.
But the best thing about taking marijuana is that you are able to stop not like the people that drink alcohol or other type of things. This matters to do that all they do is smoke because they could stop if they want to. One time me and my sister stop a man to ask him if he drink ans he told us the does and he had tried to stop bus he couldn't because his body was to use to it.
