I have learned to never smoke with people who hate cops just because they are cops, Brag about doing jail time, Pick fights at any chance they get... just to prove they are the toughest fish in the pond, people who brag about anything, and people more than 3 years younger than me. Every person I have dealt with in those catagories have lead me down a path of higher risks. And when I stopped hanging out with people like that I found that I was the only smoker I knew, and now no one is around to leech off me either, as those kinds of people tend to take pride in mooching, and no pride in buying their own.
