If you go to school, ask like minded people who you might think are into smoking and ask them.

If you work, do the same thing, ask around.

If you do neither, you really should do one, but hang around where the younger crowd hangs out and ask around. Go to some bars if you're of age and ask around.

The only way you'll find it is by asking, so just look for people who you think maybe into smoking and ask them.
