What do they look like?

Like small bell-shaped mushrooms that grow in Britain mainly between September and November. But so do many other species - some of which are poisonous & can cause serious illness or even death. If you're a newbie go picking with an experienced user & use a good full-colour guide.

Mushies are natural so they're safe & friendly, yeah?

You would think, but hose harmless-looking little mushrooms can give you stomach pains, sickness, dizziness and diarrhoea. As with any hallucinogen you can have a truly nasty & terrifying bad trip - and once it's started you're in it for the duration & can suffer fear, anxiety & depression afterwards.
