I believe this is probably the same "Black Label Premium Blend" that I smoked for 4 months. Discontinuing use resulted in an awful 4 day withdrawal that was nothing like quitting marijuana or JWH. I was in a bath tub most of the time, shaking, cold, drinking nothing but gatoraid, unable to eat much. It was awful. Then 2 weeks later I developed full blown psychosis, was arrested, and later court ordered to a psychiatric hospital. I'm still trying to figure out what was in that stuff. I know someone previously suggested AM-2201. An employee at a smoke shop once told me that he suspected mephedrone or MDPV. I've never done bathsalts but the come down is what I imagine its like coming down off of crack or speed or something like that. That's sort of what I'm leaning towards thinking is that the new 'synthetic marijuana blends' are being laced with bathsalts, but I'm not sure. Maybe AM2201 has awful withdrawal too? Unlike THC or JWH. Any thoughts?
