LSD is odorless and tasteless, soluble in water, and is taken orally often added to blotter paper. The effects of LSD begin usually after 30 minutes of ingestion and include dilated pupils, increased blood pressure and heart rate, elevated body temperature, nausea, numbness, and tingling sensations.
Hallucinations occur involving the senses of sight, sound, and touch.
Perceptual disturbances with regard to spatial relationships, such as distance, height, and depth may also happen. Users may experience severe mood alterations with feelings of despair, panic, fear of death, insanity, and loss of control. A post-LSD depression may occur, and suicides have reportedly developed from LSD use.
