Im sure this is to be found somewhere on this site but....at the mpment when i smoke i do it of foil (i have many years experience of smoking other substances off foil so am skillful) however although I can always get a decent hit , the second one is very hard as my eyes go in and out of focus so I was gonna get a meth type pipe . With these do you just drop the spice in to the bowl and heat the glass? I cant make anything as im hopeless would a different pipe be better , like a hash pipe?
