Some of the most potent cathinones are much more potent than freebase cocaine and as I noted, at higher doses, the subjective effects diverge. For some, 100mg (a point) would be an overdose by any normal standard.
I only mentioned it because several people mentioned to me the fact that there was a 'new scam' targetting crack users. It's impossible to know for sure what on earth is in those pipes but it's been known for decades that benefits arrive in the bank accounts of claiments in the early hours. Go to the dodgy area of any sizable town and there will be people trying the ATMs from about 2AM onwards and dealers ready to supply.
So from the perspective of a scammer, it's the optimal point at which to steal. Yes, most people can only take £250-£300 day out, but that's more than enough to make people think of ways to seperate people from that money.
But it WAS specifically crack users.
I really don't know much about crack or indeed cocaine in general as I find it dysphoric. But when someone is on a 'crack mission', there judgement is liekly to be severely impared. They are also much less likely to go to the police.
I don't know if it's related but a new cathinone referred to as 'crystal' has turned up. I only know two people who tried it but they noted that it seemed to have stimulant, opioid and NMDA-antagonist activity. Now there ARE compounds with that profile. A couple of them very cheap to make. But as with any drug experience, most people struggle to put the effects into words. They both said that at once it WAS stimulating but 'pinned them to the spot' - which is an odd combination. Now they used it together and in a safe space, but who knows if it makes someone suggestable? Maybe.
