I've drank in the past. I also smoked sparingly (only when drunk, or when all my friends would leave the room to have a cig, making no sense for me to wait inside by myself, or being outside in the cold without a smoke). Now I'll only catch a beer or some wine, or maybe a scotch neat every so often. No more smoking nor hanging out with potheads (because you can get second-hand high, you know).
