That article isn't about 4-MAR. Some people reckon it doesn't have the hypertensive effects of it's cousin, and I believe there's only been one death from it, if it even was 4-MAR. I found it quite stimulating and chatty, but also smooth and functional. Not jittery, like normal amphetamines. Has no one else had it? I thought it was highly sought after, but perhaps it's just that rare.
Also, the stigma thing is regarding meth, I believe. A lot of my mates do the usual stimulants, but wouldn't touch meth. Too many Daily Mail articles, and believing Breaking Bad is the usual outcome of meth use.
