What utter shite, why do they think the government has foresnsic labs
More bullshit. There are unthought of cathinone, amphetamine, tryptamine, fentanyl & pethedine analogues that are illegal because of the wide ranging scope of the amendments orders (esp the one for the cathinones)
Personally I think a decent replacement would be 1-(2-thienyl)-2-methylamino-1-propanone and a variety of other non cathinone nased stimulants. If they'd ask, I'd tell them which ones are the best bet rather than this trial & error being employed at the moment
