Ah what should I do about smoking?

I'm lying in bed, kind of wanting a cig. I just smoked a few this weekend after not for like 4 months (I didn't quit, I just started 4 months ago, only when I go out). So, some of my friend's smoke, and my bf smokes, so idk what to do? I want to stop, though. Is it okay if I just drink and smoke weed? Is it possible for me to smoke a cig or 2 once a week, or is my personality too addictive?
