Depends. With friends at college I drink, this summer I was at a lake to get away and code, and drank very little. I've smoked pot everyday for periods of time, both productively and not, and have no problem stopping when I need to. Nicotine is a bit harder... you definitely get the physical addition. I'm working on kicking it though. I've found that the busier I get, the less drugs and alcohol I consume. Or at least my drug intake changes to stimulants like coffee and nicotine. But I don't really feel bad about adjusting my habits as needed, there's nothing to "miss", I'm just choosing to do something else with my time. Also, what I do is in a large part dictated by who I am around, and what we do together socially. I have teetotaler friends, or friends who drink but never smoke, and I've never had an issue with them not participating. Though these friends are usually down to hangout if we go to a bar or something, since we'll be having a good time anyways regardless of consumption. Do what you feel, man. :)
