Lysergide (LSD) is a hallucinogen. It is often sold on blotting paper, which is usually imprinted with a colourful cartoon or design. Although abusers generally take it orally, the tabs of blotting paper are also placed on skin areas that readily absorb the drug into the bloodstream, for example, under the eyelid.

When ingested, LSD takes effect within 30 minutes

Its effects are strongest after 3 to 5 hours and can last up to 12 hours. Bad ‘trips’ can trigger severe panics, paranoia and confusion. After a ‘trip’, the abuser may feel depressed.
