it wouldn't surprise me.
I've not seen any other RC for sale (in physical stores, or legit [clear web] online sources) in Australia for over 5 years - and the only things that I ever saw before that were the odd (unnamed) powders in a vial. probably cathinones of some sort.
...but SCRAs are
still around - and apparently not hard to find - in Australia, despite being specifically banned throughout the federally, and in most - if not all - states.
I think over here, the popularity (and profitability) is helped by the mining industry, which pays well and has helped push mandatory pre-employment drug-testing into the mainstream.
I got fucking drug tested for a job I got at a community library, FFS...
so, for a long time, the people buying the synthetic weed blends were miners who couldn't risk a positive piss test (but
could risk stroke, seizure, unexpected OD etc etc - and afford to pay through the nose for the nasty crap).
I guess people need to do
something to demonise cannabis, because it's not doing a very good job of demonising itself.
