every so often i scrape my piece to get a nice little resin sesh. i find that i can get really baked off this stuff. why is that? isnt all of the thc burned away with the weed?
It depends on what the resin is and how strong it is. If its made of a poisonous substance, then it would be dangerous to eat with. Also if its fragile, there is a chance a piece can break off and cause you to choke.
Use a tarp. Rubber sheets usually don't stay on a King size Mattress.
