Mephedrone. That "behind the counter, indian/arab clerk shit".
How did the comedown feel?
It has a bad comedown. Worse than methamphetamine. Not too unlike coming down from coke. The initial, "oh shit, need some more" comedown. Probably a stronger comedown than cocaine, yet lasts slightly longer.
The high, probably best compared to meth and coke. Not as long lasting as meth, yet not as TRULY euphoric as good coke. All with a touch of MDMA. You feel super pumped and happy. Everything is good. Hard to make the buzz go the wrong way...
Until you've been up 2 days or so. It's unlike the 72+ hour trip you get from staying up too long on amphetamines, it seems to cause trippy effects much sooner. Around the 2 day mark. Music can start to be heard (not only according to my friend, but his friends as well) in the midst of pure silence. Maybe even people talking. THIS showed my friend how abnormal this stuff was, especially the tripping before 48 hours...
Not to mention, EXTREME vasoconstriction. Purple elbows where your arms have been on arm rests of a chair, for example. Purple knees out of no where/no cause other than the byproduct of the drug in your system. Numb toes from keeping a knee or two too bent. All the while having fairly extreme ups and downs in between each dose.
Dosing.... always start slow and low. What have you got to lose? ESPECIALLY with something so strange and potent as this crud. .1g is going to be on the high side for insullfation. You should, though, get an EASY 6 fat lines from a .5g amount. And each one should not leave you lingering for more. Not until 1+ hours. As with anything, quality is diverse in everything, about everything, everywhere.
I've had friends do some that absolutely rocked their world, and also they have done some that was potent, but nothing like others they have had. They said there is an orange kind that is so good it should be illegal. Oh wait, it is. But, also, the come down is so rough, they were glad it's illegal. It's too easy for your average, no control, will not be influenced, mind set, do what I want "inexperienced" user to wait at the tobacco store for 2 hours before open, and freak out everyone in the "normal" world.
