What Happens When You Take LSD
When you ingest LSD, it quickly enters your bloodstream and crosses the blood-brain barrier. The drug binds to serotonin receptors in the brain, especially the 5-HT2A receptor, which causes altered sensory perception and mood changes. The onset, peak, and duration of effects depend on the dose, method of ingestion, and individual metabolism. How long does acid last
