Saw this on ITV in the UK around mid-late 90’s. A group of college students hooking up, taking drugs etc. Set in 60/70’s,(I remember them wearing flares) it was a drama.
Several love scenes including one with a blonde lady in the back of a van. Most of the women didn’t seem to wear bra’s which to my teen self got my attention. I think one of the group possibly died, maybe from drugs but I may be confusing it with another movie.
