About three weeks , after a party hosted by a friend in my teens and really overdoing it. I'd been given my first ever MDMA pill by one of the girls there, by all accounts, quite a good one, clean and a lot of alcohol flowed, my own contribution to her get together had been a couple of botttles of inhibitor-free ethyl ether and some of a traditional amazonian tribal native psychedelic snuff called yopo.
But on the way home, I took a ride with her mom to score some 'phet, tenner for 3g, so assumed I was going to get what I'd paid for, namely 90% glucose most likely. Only the dealer must have been some family friend or something, and had,on hindsight, obviously decided to give me a good deal on some really high quality stuff. After doing most of it over the night, fuck me the comedown lastes nearly three weeks, no sleep possible, although by the end my eyes were closing in micro-sleeps uncontrollably and the sleep deprivation (the actual whizz had long since worn off, this was three weeks afterwards) had shit going on like seeing big black rifts opening in the walls as I was taking a shower. Interesting enough but still pretty fucked up.
In fairness, had it been anyone and anywhere else, I almost certainly would have been right, 3g for a tenner pretty much would have meant weak fucking garbage. But that particular guy and me with the specific company I was in resulted in quite the opposite. I certainly didn't expect to get what in the uk, often gets referred to, most inaccurately, as base (its not amphetamine freebase, that is a somewhat caustic oil, and a liquid, so called base is just really strong (one hopes) amphetamine paste that has often got a distinctive floral kinda smell, that stinks of leftover precursor sometimes )
