LSD (Lysergic acid diethylamide)    Stimulating one of the neurotransmitters in the brain, serotonin, LSD produces hallucinations dissociating the user from reality. Users often report having the ability to see and hear things without stimulus. "Synesthesia" is another effect, causing the user to hear matter that is only visibly perceptive such as hearing colors or associating odor to audible sounds such as "smelling voices." LSD is often concealed in blotting paper and cut into designer square pieces, the drug is absorbed via the skin or oral tissue. Each square piece represents a single dose which costs $5-7 each. In Indiana, LSD is predominately sold and consumed by males between ages 18-35. However, younger cohorts are experimenting with the drug as access increases. According to the National Survey on Drug Use and Health, 9.7 percent of Americans aged 12 and older reported using LSD once in their lives.
