I used to love them... but now the only way I like my joints is unrolled and in my vaporizer. ;-) I don't do joints any more. Even just one or two a week gave me a nagging smokers cough... and I wouldn't even hold the hits in very long.
Vapor is awesome! No cough at all anymore, even while smoking and holding in the hits as long as I can. I can smoke like 3 times less for the same effect too. .. probably b/c I'm inclined to hold it in 3x longer. And with my ubie or vaporstar I can do vapor on the go too.
The only downfall is that I liked the safety of carrying just a joint with me. If I get pulled... just eat it. If some dumb pig tries to catch me smoking it... same thing; spit on it and eat it. No evidence = nothing to prosecute. But with a vaporizer, you'll always have paraphenalia on you. I keep it in an airtight contairner in my trunk just in case I get a speeding ticket or something. But still, it is more risky.
Damn... I can't wait until pot is legal.
