In its pure form, LSD is a white, odorless crystalline material. LSD is also so potent that the effective dose of pure drugs is so small that it is almost invisible. As a consequence, it is usually diluted with other products. The most popular kind of LSD is drops of LSD solution dried on gelatin sheets, bits of blotting paper or sugar cubes that release the drug when swallowed. Also, LSD is sometimes marketed as a vapor, in capsules or in tablets.
LSD stands for Lysergic acid Diethylamide. It is a street drug that is illegal and comes as a clear, colorless liquid or white powder.
Some people inhale or inject it through the nose (snort) or into a vein (shooting up).
