im smoking mine right now. Its a great decorative item (if you collect glass and whatnot) .... and it is really fun to smoke. You can take HUGE hits off it.....
It relaxes you too. Be carefull though, they can give you a headache.
I use mine as an alternative to cannabis....even though it doesn't get you high..it saves $ on green. try wood coals!
Its good if you like smoking, especially if cigs aren't your thing.
You really dont have to clean them either....Ive had mine for a year and its good as new.
remember, the expensive tobacco is WORTH IT...there is a noticable difference imo. It goes a long way too.
its also good for social smoking.
DONT put only weed in it, grind up REGS and spread it in the bowl with the tobacco. Make sure not to only put it on the top, it'l waste.
