It's probably the street drug with the highest average purity (up to >90% for crystal meth).that drug is by far the dirtiest and the fast people inject that is more worrisome to me because of the by products and solvents used in the making of it. I hope all you IV users are safe out there
Some people inject euro speed (amphetamine sulfate) which is sometimes ~15% pure, or street heroin (5-25%).
