I'll probably never stop smoking weed unless it affects me. So i don't know. Cigarettes i'll probably quit within the month. I don't really think you get physically addicted to cigarettes. Just mentally addicted.. kinda like weed in ways. Weed can only be addicting if it's mental addiction. My lungs have had their share of smoke, and eventually all that shit catches up to you. I do still need my lungs for many things. I guess we will just have to see. But weed, i won't stop smoking.
