Synthetic cathinones-related effects rely on two major mechanisms, i.e. monoamine uptake blockade resulting from transporter inhibition and increased monoamine release as well as the combination of these two mechanisms (Table ) . Cathinones are all potent inhibitors of norepinephrine reuptake transporter, but marked differences exist in their inhibition profiles regarding dopamine and serotonin reuptake transporters as well as their ability to release monoamines, possibly explaining clinical differences reported in their effects and toxicities. MDPV acts as a potent and selective monoamine uptake blockers but has less impact on monoamine release than cocaine. Mephedrone and methylone act not only as nonselective monoamine uptake inhibitors like cocaine but also increase serotonin release similarly to MDMA. Cathinone highly inhibits dopamine but is a less potent serotonine reuptake transporter.

Users report a number of negative physical and psychiatric effects associated with synthetic cathinones . The main NPS adverse effects are summarized in Table . Cardiac, psychiatric, and neurological adverse effects are the most common reported ones requiring medical care. NPS use may lead to violence, homicidal combative behavior, self-mutilation, coma, and death . Acute toxicity is the leading cause of NPS-induced fatalities. However, concomitant synthetic cathinones and other drugs use have been reported in numerous fatalities, limiting any definitive conclusion regarding their implication in the onset of death.

Synthetic cathinones and synthetic cannabinoids represent more than two thirds of the NPS available in this new drug market. The overwhelming majority of synthetic cathinones is produced in China and South East Asian countries (3). Mephedrone (4-methylmethcathinone), methylone (3,4-methylenedioxymethcathinone), 3,4- methylenedioxypyrovalerone (MDPV), methylethcathinone (4-MEC), 3-fluoromethcathinone (3-FMC), 4-fluoromethcathinone (4-FMC), buphedrone (alpha-methylamino-butyrophenone), butylone (beta-keto-N-methyl-3,4-benzodioxyolybutanamine), methedrone (4-methoxymethcathinone), pentedrone (α-methylaminovalerophenone) and naphyrone (naphthylpyrovalerone) are some of the most well-known synthetic cathinones (Table ) .

Khat (also known as qat or chat) comprises the leaves and fresh shoots of Forsk, a flowering evergreen shrub cultivated in East Africa and the South-West Arabian Peninsula. Khat leaves are typically wrapped as a bundle in banana leaves. The principal active components in khat are cathinone and cathine (norpseudoephedrine) (see also Drug profile on synthetic cathinones). Chewing khat releases these substances into the saliva; they are rapidly absorbed and eliminated. Both cathinone and cathine are closely related to , and the pharmacological effects of cathinone are qualitatively similar to those of , although it is less . Only fresh leaves are chewed, because cathinone soon degrades into old or dry plant material. Analysis relies on the characteristic appearance of khat and the presence of cathinone and/or cathine. Khat is not under International control, but is scheduled by some Member States. Cathinone and cathine are listed in the 1971 United Nations Convention on Psychotropic Substances under Schedules I and III respectively.

The injection of synthetic cathinones is reported rarely and is restricted to specific groups of high-risk drug users (Austria, Belgium, the Czech Republic, France, Germany, Ireland, Poland, Spain and the UK). However, in Hungary and Romania, a more significant prevalence of synthetic cathinones injection was identified among large cohorts of drug users .
