Mephedrone acts as a psychoactive drug


Mephedrone acts as a psychoactive drug that is a synthetic cannabinoid with stimulant properties. It stimulates the central nervous system, which in turn excites physical and mental functions. It is also termed as 4-methylephedrone or 4-methyl methcathinone (4-MMC).


This bath salt drug belongs to the cathinone group of drugs, which is naturally obtained from the Khat plant. This drug was initially advertised as a research chemical and considered as a legal drug as an alternative to other drugs like ecstasy, cocaine, and speed. People use it occasionally for pleasure as it speeds up the action potential between brain, and body producing similar effects like cocaine, MDMA, and amphetamines.

Mephedrone is a white or yellowish powder that is present in diverse forms like crystals, capsules (filled with powdered mephedrone), pills, powder, and injections. It has the smell of vanilla, bleach, electric circuit boards, and urine. The powdered mephedrone is either swallowed by mixing with foodstuff or drink, inhaled through the nasal pathway, and bombing by cigarette with effects enduring to 2-3 hours. The injections of mephedrone are taken intravenously with effects of enjoyment and relaxation that persists for half an hour. Mephedrone is most frequently consumed with alcohol, and it improves the psychostimulant effects of mephedrone by increasing the release of dopamine at nerve junctions.
