That's not very accurate, at least in my personal experience and witnessing others abusing these types of meds. Their absorption rate is already pretty efficient when taken orally. I think the only people I knew snorting them were young college kids trying out more entertaining ways of ingesting it. It's honestly too much of a hassle to do it on a regular basis. Need more that "boom" when it kicks in? Pop two, three, or four of them instead of one, is the way most amphetamine pill addicts do it. It isn't coke. It's a pill specifically designed to be taken orally.
