Actions of Psychoactive Substances :

• Stimulants (like mephedrone, naphyrone) act like amphetamines, cocaine, or ecstasy, in that they can make you feel energised, physically active, fast-thinking, very chatty and euphoric.
• Downers or sedatives (like GBH/GBL, methoxetamine)  act similarly to benzodiazepines (drugs like diazepam or Valium), or GHB/GBL, in that they can make you feel euphoric, relaxed or sleepy.
• Hallucinogens or psychedelics  (like NBOMe drugs)act like LSD, magic mushrooms, ketamine and methoxetamine. They create altered perceptions and can make you hallucinate (seeing and/or hearing things that aren’t there). They can induce feelings of euphoria, warmth, ‘enlightenment’ and being detached from the world around.
• Synthetic cannabinoids (like Spice or Black Mamba): act similarly to cannabis. The effects of these are similar cannabis intoxication:  relaxation, altered consciousness, disinhibition, a state of being energised and euphoria.
