It's not known exactly how LSD affects the brain. Scientists believe it has to do with serotonin. Serotonin is a brain chemical that carries messages related to perception and behavior. LSD somehow disrupts that process, leading to a trip that can last for 12 hours or more. A person starts feeling high about 30 to 90 minutes after taking LSD. How the drug actually affects a person depends on many things, including the amount of LSD taken, the person's surroundings, and his or her personality and mood.
