Chillums/One-Hitters

Chillums & Onies! A straight pipe with (usually) no carb. Great for when you're on the go. 

The definition changes depending on your area. Typically, a One-Hitter, or Onie is a straight pipe with a constriction style bowl & no carb. A "Chillum" is a straight pipe style with a pushed bowl, sometimes a carb, and is generally used by smoking through your hands.

Popularized on Grateful Dead lots, so you could share a smoke with someone without sharing the germs.
