Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis.

A decrease of 60% means the final amount is 40% of the original (100% – 60% = 40%). A decrease of 100% means the final amount is zero (100% – 100% = 0%). In general, a change of x percent in a quantity results in a final amount that is 100 + x percent of the original amount (equivalently, (1 + 0.01 x) times the original amount).
LSD, a classical psychedelic, is deemed physiologically safe at standard dosages (50–200 μg) and its primary risks lie in psychological effects rather than physiological harm.
