Using a pipe:
1. Put weed in
2. Light weed
3. Suck in through pipe
4. Take fire off weed once weed is lit

Some people put tobacco with grass in pipes and bongs but I don't really like it. I think it's best to smoke pure in pipes and then mixed in joints.

EDIT: Just make sure there are no damn seeds when you smoke. It doesn't matter if the weed is dried, just make sure all the seeds are out.
