of drug (may be days or even years later!)
●Self-Reflection
●Loss of Identity and Cosmic Merging
●Mechanisms of Action
●Lysergic Acid Diethylamide (LSD)
○Schedule I
○A single dose of LSD may be between 100 and 500 micrograms → an amount
roughly equal to one-tenth mass of grain of sand
○Effects can last up to 12 hours
○Very difficult to have lethal overdose
