Excellent, unbiased resource for psychoactive drugs. This site provides a vast amount of objective, factual information on many substances, as well as subjective information based on user experience reports. Erowid is instrumental for recreational drug users, therapeutic drug users and medical practitioners alike. The harm reduction basis of the site has saved many lives I am sure; and I myself have benefited greatly from the accurate information on dosing, effects (mental and physical) with both long- and short-term use of substances.
