Idk, I think it depends on the person. I smoked regularly since 2007, and earlier this year I quit for a couple months to get clean while looking for a new job. I didn't experience any type of withdrawal physically or mentally.
Yeah, I think so too. I can smoke cigarettes every day for months and give up on them easily. It is assumed that most people that smoke are addicted and that's definitely the case but for me, I don't get addicted to it. The same can definitely be said about weed considering that it is easier for some people to let it go in comparison to others.
