THOSE ARE CALLED FUCKIN BOTTLE TOKES! bots for short.

theyre done with hash.

esentially hte concept is, you have some hash maybe 1/4" from the tip of the cigarette,light the cigarette, and stick it inside the hoel in the bototm of the bottle and wait.

Since the hash smoke is heavier and thicker, it will fall to the bottom of the bottle and condense, and the tobacco smoke is thinner and lighter, so it will escape out the top in little blueish wisps.

shit was invented in canada, just like yattis(or shottys or whatever you call em)

by the way, all this shits on wikipedia or the internet
