Pot smokers who have a daily habit, and according to how much they smoke will become very insular, and self indulgent, why let him dictate when you see your friends?....before you know it you will be living your life just how he wants you to!...pot makes you think differently...unless you start smoking yourself, you will always be on a different mind set to his. I have a son who smoked pot...it eventually ended with him becoming mentally ill, but that was because he started to smoke it when he was 16.....not trying to frighten you but I think you should very gradually back off a little, and keep seeing your friends!!!
