you're smoking a pill.. you are definitely not going to get as much drug into your body as you would using other routes.. Also, smoking the pill could cause dangerous chemicals to enter your lungs and fuck up your teeth (it really happens).. and you don't it probably you just end up burning it and ending up with a headache or worse
it's not like smoking crack.. its like if you took a piece instead of the whole thing
again it's a waste
let's say you get 10% of it.. that's 3mg.. 3MG! and you probably paid good money for it so make the most of it
