To be honest I dont worry about wasting my weed in a J.....if it gets you smashed its fine by me, I chose to some Joints because i liken to do it. If i liked smoking bongs or pipes as much as i like smoking joints i would do it all the time.
Dont be so tight with the weed people, i share my weed with who ever wants to toke it if they respirocate the favour. I get stoned everyday and for alot of the week it doesnt cost me a penny. Its called friends!
