Many recreational drugs are sold in the illegal market. LSD and cocaine are two of many hallucinogens. These drugs belong to a group of pharmacological agents that causes subjective changes in perception, thought, emotion, and consciousness.
LSD (d-lysergic acid diethlamide), seen as white, odorless powder, is commonly used as a psychedelic drug. This drug is ypically sold in liquid form or in tablets. LSD works by tightly binding and activating specific receptors for the neurotransmitter, serotonin. This causes an amplified effect and excess serotonin is released, which in turn, activates other serotonin receptors creating a domino effect.
Physical effects include elevated body temperature, increased heart rate, sweating, loss of appetite, dilated pupils, tremors, and sleeplessness. The mental effects of one dose is very potent and leads to sharp changes in sensory experiences, the mixing of senses, or a distorted feeling of time and space. Colors may appear brighter, sounds can become sharper, symptoms of synesthesia can occur, and the appearances of objects can be distorted. Usually, these effects begin 30 to 90 minutes after self-administration of the drug and the most intense effects occur three to five hours later. These are just few of many psychological effects that LSD causes.
Bad reactions to a dose is common among users. While under the influence of LSD, a user can also experience strong feelings of fear. Some reported hallucinatory effects are unpleasant such as spiders crawling on the skin or the appearance of monsters. Since the effects of LSD last up to several hours, these hallucinations can be very terrifying. Feelings of helplessness, panic, confusion, and paranoia surface, but in some instances this drug has unmasked many mental or emotional problems that were not known to the user before. The effects of LSD vary from person to person depending on many factors such as weight, size, health, and diet.
