Good job on the guide, although I can't addon, I would like to point out a few things that are entirely of my opinion, so don't take it as an offense to correct in any way.
-Blunt papers aren't just brown paper. Most have flavors and some also give a lightheaded buzz as opposed to just plain paper, plus they roll much fatter than regular joint papers.
-Rough hits aren't necessarily hot, sometimes you can rip your bubbler/bong/water-pipe and the hit can be cool, but still irritate your throat. Things like percs and diffused downstems help reduce drag.
-For sack, you should mention what a gram, eighth, half oz, oz, etc. is.
-Aluminum is good here and there as a last resort, just make sure never to heat it up too much. Although,
tin foil is what people must stress on about.
-You don't need music, but listening to some form of chill music helps mellow you down sometimes. It all depends on the user and the friends around the user, as most probably have different music tastes.
-For the dealer bit, I would never ask my dealer to smoke a bowl with me unless your picking up somewhere where it wouldn't look sketchy. Most of the time its just a "hand the sack, hand the money, split up and go" kinda thing.
-Chronic (at least here in California) is characterized as regular mids. Dank is mostly characterized as Kush or other strains similar.
For your list of weed, I've never really heard anyone say "kill" for a weed generalization. I've only seen people base it on this.
-Dank
-Mids
