Legal highs are man-made substances (chemicals) and strong stimulants that have similar effects to illegal drugs like cocaine, cannabis or ecstasy. They are sometimes called club drugs or new psychoactive substances (NPS) and provide physical, emotional and hallucinogenic effects and are marketed as a "legal" high. They range from plants, to synthetic drugs, to medicines you can buy from a pharmacy. What makes them similar is that they're all legal - but that doesn't mean they're safe. There's often not enough research about these drugs to know their potency or the adverse effects from human consumption.
