LSD enters the bloodsteam, primarily orally, after the user has ingested some form of the drug. It can also be injected directly into the bloodstream in its purest liquid form. From there the LSD travels to the brain through the blood, and mimics the chemical serotonin. Your brain is fooled into believing that the LSD is just regular serotonin, a chemical which controls moods in the brain, and so it allows the LSD to combine with the serotonin receptors in your brain. The LSD can either inhibit or excite these receptors, and because there are so many this is what causes LSD's very unpredictable, illicit effects.
