Ingesting Cannabis is a waste and it's not as good a trip; more a body stone. If that's what you want, smoking hash or Indica buds is much more economical, and it's still a better trip than brownies.

Good old fashioned Panama Red is total creeper. You smoke a few hits and feel sort of funny, but can't quite figure out if you're actually stoned or not, so you finish the rest of the joint. After a short while, you're totally cartooned out, hallucinating your fucking ass off, but still think you're not stoned enough yet, so you stuff a few flower tops into a pipe and light it up. Between four of us, we used to smoke a lid of that shit, each and every day, with absolutely no tolerance build up, what so ever.
