What do you think is the most dangerous aspect of LSD?

Unpredictable psychological effects are the most dangerous thing about LSD. People can experience delusions and visual hallucinations that can be frightening. In fact, "bad trips" can include terrifying thoughts and nightmarish feelings of anxiety and despair that include fears of insanity, death, or losing control.
