UK law on psilocybin mushrooms and grow kits
- Grow kit legality: An “inoculated” grow kit, one that has been started and contains active mycelium, is illegal to possess. Since mycelium produces psilocybin, the kit is considered an illegal Class A drug.
- Spores vs. cultivation: While dormant spores for magic mushrooms are legal to possess for research or microscopy purposes, cultivating the spores into mycelium is a criminal offense.
- Penalties: Maximum penalties for possession of a Class A drug in the UK include up to seven years in prison, an unlimited fine, or both.
