It also bypasses the first-pass metabolism and intestinal epithelium this way.Yeah well inhaled meth enters the brain much more rapidly and is just more fun overall
In addition, (and someone please correct me if I'm wrong), I believe when Meth is administered any other route than orally (ingested) you miss out on the 7+ separate Methamphetamine metabolites , some of which likely have the potential to be beneficial to the brain/body.
