the can vary from (what i've seen) 40 bux all the way up to 650.....and they are supposed to be healthier than just smoking becasue it doesn't burn the bud and produce smoke it just heats it up high enough to not burn it but to release the active ingredients needed to get high......it's also supposed to be a very clear headed high...way diffrent from smoking but i can't verify it cuz i've never used one
