one hit will get you fucked up, if you are the cheifer type of smoker (take huge ass hits) if you do little normal or little baby hits you might have to hit a couple of times..... and one gram does last awhile....i've had mine for quite a while now and still have stuff left....i would say start with one hit, set the pipe down and sit there for a minute...if you didn't feel anything take 2 hits that are smaller than the first one...just take it slow, it's better to 'waste' some at first, then having a horrible trip by over doing it....
