I am not a very experienced cannabis user, but I recently purchased an ounce of resin off a reasonably trust worth source. Is there any way I can easily get an idea of the quality of the stuff? I dont wanna be smoking rat poison! lol I had smoked a bit, and thought it was pretty sweet, no weird side effects although I have been unusually paranoid... But that may be normal. It is dark brown in appearance, reasonably hard, crumbles fairly easily. Apologies if there are already threads on this, But i have looked and couldn't really see any! I just want a quick, easy, simple answer. Thanks for your time.
