LSD is a semi-synthetic drug derived from lysergic acid, which is found in a fungus that grows on rye and other grains.
LSD, commonly referred to as
"acid", is one of the most potent hallucinogens. It is usually sold
on the street as small squares of blotting paper with drops containing the drug, but also as tablets, capsules or occasionally in liquid form. It is a colourless, odourless substance with a slightly bitter taste.
