Well I would suggest just getting to know some people, if your of age, check out a local bar or club with live music. I've worked in the music industry for a while and even though not all music artists smoke, a good number of the crowd does as well as many performers... May be a way to "spark" up a conversation
Also, the auto industry is infamous for tokers... I don't want to generalize but a good number of people that I have worked with in the auto industry also toke, more so than not.
That's my suggestions... you could always save that last bowl, approach some people that look like they might smoke, and ask them if they want to blaze... good way to let them know your cool as well as you can let them know your looking for some...
Hope this helps..
