People have drinks in a bar. Tim and his buddies light a bong in their car that soon fills with pot smoke. One of Tim's friends rolls his own joint, and both he and Tim smoke it while Tim also drinks liquor from the bottle. Wheeler burns some pot in an old, outdoor burner and both he and Tim ingest the smoke that we see billowing out from the tree under which they're hiding. We see Drugs taking some hits from a bong.

Tim and others smoke a joint. We see Drugs doing another bong hit. At a party, people drink beer while another person rolls a joint. We then see Drugs and Irv smoking a joint. Later, Irv appears quite high from the drugs.
