Well for sure that'd be acceptable I guess (well: talking from the chemical/freebase route anyway). But please believe me when I say that I saw (ended up with) way way way worse, and more than once, somewhere around the 2000's mark. Kinda cured me (for want of a better phrase) i.e. it just got old. Not to mention my losing my shit with certain individuals being bad for my health and psyche!
I'd love for somebody (now) to actually do a test with what they consider to be good Cocaine. Just for the hell of it. And no: I ain't paying for the loss (or potential medical bills)!
Sure would be interesting though.
