Summary
LSD is an extremely potent classical psychedelic with a relatively safe physiological profile but powerful psychological effects. Tolerance develops rapidly (within hours) and dissipates within 5-7 days. Set and setting are crucial for minimizing adverse reactions. Not recommended for individuals with personal or family history of psychotic disorders. While physiologically safe at standard doses, LSD can impair judgment and cause intense psychological distress.
