The hydrochloride salts of buphedrone and pentedrone, two new designer drugs, have recently been identified in shipments destined for Canada. To confirm their identities, we have synthesized reference materials for these methcathinone analogues and herein provide complete characterization by FTIR, FT-Raman, ¹H NMR, ¹³C NMR, GC/MS and ESI-HRMS.

Identification of polymorphism in ethylone hydrochloride: synthesis and characterization

TLDR
This report, alongside the recent article on the single crystal X‐ray structure of a second polymorph of this synthetic cathinone, is the first to confirm polymorphism in ethylone hydrochloride.

TLDR
Among the adulterants found in these samples, caffeine was the most frequently detected substance, followed by ethylphenidate, which highlights the prevalence of SCat in seized materials of the Portuguese market.

Analyses of second-generation 'legal highs' in the UK: initial findings.

TLDR
It was found that 70% of NRG-1 andNRG-2 products appeared to contain a mixture of cathinones banned in April 2010 and rebranded as 'new' legal highs, rather than legal chemicals such as naphyrone as claimed by the retailers.

TLDR
Six out of 7 legal-high products purchased and analyzed for their content did not contain the advertised active ingredient and five samples contained the controlled substances benzylpiperazine and 1-[3-(trifluoromethyl)phenyl]p Piperazine combined with caffeine.
