A long-acting psychedelic-empathogen with a broad method of action in the brain. Not suitable for combination with many other substances. Used as an anti-depressant in the Soviet Union, but later found popularity in the RC scene, mainly in the UK.

Harm reduction

  • Set and setting shape a psychedelic experience more than the dose does. Plan the room, the music, the company and the exit before you take anything.
  • Have a sober person present, or at minimum someone who knows what you have taken and can be called.
  • Do not redose to 'make it stronger'. Tolerance to psychedelics develops within an hour, so a redose mostly extends the experience and increases the risk of a difficult one.
  • Avoid combinations with lithium (seizure risk) and tramadol, and be extremely careful with cannabis, which sharply intensifies the experience.
  • People with a personal or family history of psychosis, schizophrenia or bipolar disorder should not use psychedelics - this is the clearest contraindication in the literature.
  • Never drive, cycle or operate machinery, and do not take psychedelics in public places or around crowds you cannot leave.
  • Physically: expect dilated pupils, raised heart rate and reduced appetite. These are normal. Chest pain, fainting or seizure activity is not - get help.
  • Frequency matters: repeated use within days has sharply diminishing returns and increases the risk of persistent visual disturbances.
