The most common form of LSD is as a liquid that has been transferred onto a small paper square (known as "blotter"). Additionally, it is also found as a powder or crystal, dried on gelatin sheets, put into capsules or on sugar cubes, or laced with other drugs. Users usually chew or swallow them, allowing the drug to be absorbed through the gastrointestinal tract.It also is inhaled or injected.
