Sure its all in your head you dumb fucks, but once you get in the habbit of smoking every day for a few years+ it becomes something else. Now it becomes a routine that you are accustomed to and basically 'need' to feel good or normal. After smoking consistently for a long ass time once you decide not to smoke one day you will find your appetite is def affected, you may find that you have a head ache, and sleeping at night will be a total bitch. So you see it isn't really an addiction but it is a huge huge habit that forms and is incredibly hard to break the habbit. Especially when everyone of your friends smoke and msg you through out the day with the question wanna sesh? Some of you need to get real, when i use to smoke a few times a week it would be easy as hell to just be like alright no weed for today, or can't find bud no biggie. Now it is essential to having a normal day.
