I think where Dee is coming from is based on his own experience.
Yeah I quit pot round about the turn of the century. I moved away back to my folks - didn't want to smoke it there, didn't know anyone who smoked let alone sold, and after the withdrawal phase I didn't miss it. (Took up drinking in earnest but that's another story) ,
Moved around a little more, smoked a bit here and there for 6 months based on who I was hanging with. Again not really bothered one way or the other.
Got back into my own place eventually and bought some weed off a guy.
You know how that story ends.
