High doses or particular reactions to the drug can be fatal due to the increased risk of convulsions, coma and brain haemorrhage. Regular, heavy use of amphetamines can cause hallucinations, paranoia, brain damage and mental illness. Pregnant women who regularly use amphetamines may suffer premature birth and the drug can be passed onto babies through breast milk. Back to top LSD and magic mushrooms LSD is a hallucinogenic drug which distorts the way the mind perceives things. Its effects are usually felt within half an hour of use and last for up to 12 hours.
Experiences vary according to the individual so are difficult to typify.
Users report that objects appear much brighter and may seem to ge moving or distorted. Hearing may also be intensified and the user's feeling of time and place may be distorted. Once a 'trip' has begun, it is impossible to stop or control it. The drug tends to exaggerate the mood a person is feeling when they take it. Users do not become physically dependent on LSD, but some may experience a psychological dependence.
