That hippy kid that gave me the bong said they sell hash at that joint. I should check that out. I used to stick a chunk of hash on a bent safety pin, light it, cover it with a drinking glass and then slide the glass full of smoke over to the edge of the table and inhale it into your lungs and hold your breath as long as you can....it's very...exotic. We called it "hash under glass"
My late sister sent me a nice collection of glass bongs and other smoking equipment in 2017... But of course it's all still illegal here.
