Mephedrone - "Shake 'n' Vac"??
So I went to the headshop today and asked for mephedrone. They had a new guy at the counter, and he looked confused for a sec, and then said 'oh! you mean shake 'n' vac, right?' Well, I've noticed the drone they sell there says 'shake n vac' on the packet, so I tell the guy yeah, that's what I mean. He says, 'We don't call it mephedrone cos we put other stuff in too, that's why it costs more.' I ask what stuff, and he says lots of things, including (some product name I can't remember) to 'help it go through your body more clean like'. I say fine and take it.
I hadn't gotten any drone from there for aaaages, and I'd forgotten how different it is to the 99.5% mephedrone you get on the internet. This is how it's different, okay:
-quite a bit stronger at first
-slower coming on, and peaks after the same amount of time as normal drone would, BUT it seems to last about an hour more than drone would after the peak
-literally twice the price

-pure, solid white colour (rather than crystally-sparkly-white)
-smells kind of 'clean', a bit like air freshener (but it only smells a tiny bit)
-tastes like drone, but less harsh/chemically
-much less drip
-makes my gums/mouth numb, like coke
Does anybody know what's actually in 'Shake 'n' Vac'? Or, can anybody guess what might be in there from my description?
thanks xx
