Never had any problem quitting smoking when I needed to, it's all a state of mind..of course I'd say being addicted to tobacco like a crackhead to crack..marijuana is less addictive than coffee to me, and I had no problem quitting coffee, just the simple desire to go pick one up on the way to work..wasn't that hard to not do..I wish cigarettes were as "addictive" as marijuana..but that's why cigarettes are in fact legal..it's nearly a guarantee that smokers will return the next day to buy yet another pack..with marijuana they cannot ensure a steady flow of users/buyers
