Something that's been bugging me for awhile is why people think iso is used as a cut because it does something like meth when ingested. I don't think it does much of anything when ingested, but from the DEA .gov site: "N-Isopropylbenzylamine hydrochloride is not controlled, and does not have CNS stimulant effects at typical methamphetamine dosage levels."Just for the record and everything.
