And we don't know how neurotoxic this stuff is yet, right?
What about the people who have been addicted to the stuff and doing multiple grams each day for months? How come they have been ok?
Because this stuff only affects a few ppl that are sensitive to those effects, IMO its "safe" for the "insensitive ones".
Apart from that those ppl could have suffered heart or brain damage, just not the apperant extreme vasoconstrictive effects.
With safe i mean those ppl probably wont turn blue, but its still an unresearched agent.
