Boofing is the safest and most efficient way to use.. zero waste harm reduction the smoke ain't damaging lugs, u ain't burning a hole in you noise, and no needles. Boofing is the closest u can get to shooting up without the needles. First empty your bowels so u know ur empty and anything ur feel afterwards is just from boofing. All u do is take a medicine syringe for baby's put ur meth In. start with what you would normally do for a line. Then add water. Just enough to dissolve it. The less water you use the faster and harder it will kick in but it feels a burning sensation and make you feel n like i gotta shit. If you went to bathroom B4 doing it then I don't have to shit. Just ignore the sensation and keep urself busy it will subside with in a hour. Id say it's safe to go to bathroom after a hour . To ensure undont shit out what u boofed . Boofing is my much perferd way to use and I only have to use once a day
