Synthetic Cathinones

"Synthetic cathinones are related to the parent compound cathinone (Figure 1), one of the psychoactive principals in khat (Catha edulis Forsk). Cathinone derivatives are the β-keto (βk) analogues of a corresponding phenethylamine. The group includes several substances that have been used as active pharmaceutical ingredients (API) of medicinal products, e.g. amfepramone (diethylpropion; Figure 2). Since the mid-2000s, unregulated ring-substituted cathinone derivatives have appeared in the European recreational drugs market.

Synthetic Cannabinoids

"Synthetic cannabinoids, also known as synthetic cannabinoid receptor agonists, are a group of drugs that mimic the effects of a substance found in cannabis called tetrahydrocannabinol (THC). THC is responsible for many of the psychoactive effects of cannabis which give that feeling of being ‘stoned’ or ‘high’ (Gaoni and Mechoulam, 1964; Huestis et al., 2001; Pertwee, 2005a; Pertwee, 2014). These effects are caused by activating a receptor in the brain called the cannabinoid receptor type 1 (CB1 receptor) (Huestis et al., 2001; Pertwee, 2014).

Number of New Psychoactive Substances Continues to Grow

"By the end of December 2017, the EMCDDA was monitoring more than 670 new substances that have appeared on Europe’s drug market over the past 20 years. This total includes 51 substances that were reported for the first time during 2017 (Figure 1), namely 13 opioids, 12 cathinones, 10 cannabinoids, 4 phenethylamines, 3 benzodiazepines, 2 tryptamines, 1 arylcyclohexylamine, 1 arylalkylamine, 1 piperidine/pyrrolidine and 4 substances that do not belong to these other groups.

New Psychoactive Substances Defined

"In the operating guidelines on the early warning system, EMCDDA [European Monitoring Centre on Drugs and Drug Addiction] made it explicit that 'the term ‘new’ did not refer to newly invented, but rather ‘newly misused’' substances as 'most of the drugs in question were first created many years ago.'20 In fact, investigations into the potential use of piperazines as anthelmintic have been reported in scientific literature since the early 1950s.21 Yet they only started to emerge as a health problem in several countries in the decade 2001-2010.

Prevalence of Past-Month Drug Use in Norway

"The findings on drug use are based partly on positive findings from urine tests and partly on reported use during the last 30 days. The levels are overall quite similar to 2012. A proportion of 10 per cent reported having used an illegal morphine substance during the past month, 33 per cent cannabis, 16 per cent stimulants and as many as 42 per cent benzodiazepines. This figure includes both prescribed and non-prescribed benzodiazepines. Twenty-five per cent of all patients report having been prescribed the drug by a doctor. In other words, the others must have used illegal sources.
