DOSINA

Zopiclone

Depressant

A nonbenzodiazepine sedative sleep aid (Z-drug), which can have hallucinogenic effects if taken while awake. Often causes users to have a metallic taste in the mouth for ~12h. Has been reported in some cases to cause certain users to black out, redose excessively and undertake dangerous activities such as driving.

Harm reduction

  • Depressants are the class where mixing kills most often: alcohol, benzodiazepines, GHB/GBL and opioids all suppress breathing when combined.
  • Never use alone. If you use alone, set up a check-in call with someone who will call emergency services if you do not answer.
  • Measure liquid doses with a syringe. Bottle caps, teaspoons and 'glugs' are how people take ten times the intended dose.
  • Sedation can be delayed. Do not re-dose before you can feel the previous dose fully.
  • Do not stop daily benzodiazepine or alcohol use abruptly - withdrawal can cause seizures and is potentially fatal. Taper with medical help.
  • Signs that someone needs emergency help: breathing slower than one breath every 4-5 seconds, blue lips, snoring that will not stop, unrousable, vomiting while unconscious.
