i'm not sure.. we didnt really pay attention to it... we ended up throwing out the bowl pack and packed a fresh one! We figured that since we were smiking via bong we'd be ok, i cant imagine the glass vaporizing or somthing liek that... but this was a couple months ago and were both fine so whatever.. its all good

Smoking Glass One time, a friend and I threw some weed in my coffee grinder and forgot that there was a little glass screen in the grinder too... we had realized what we had done but there was no turnign back so we packed it into his roor (thinking the water would filtrate it) and toked up... to say the least... it sucked!!! had sore throats for about a week.
