Delta‐8‐tetrahydrocannabinol (THC) has activity in man similar to that of its double‐bond isomer, delta‐9‐THC. Its relative potency to the other isomer, as judged following both oral and intravenous administration, is 2:3. Intravenous administration of ethanolic solutions of cannabinoids in clinically active doses is feasible and desirable for experimental purposes. A range of doses of 1 to 6 mg of delta‐9‐THC intravenously produced a wide spectrum of cannabis‐like effects. Relatively simple clinical techniques clearly detect cannabis‐like activity in man, making both qualitative and quantitative camparisions of unknown materials with delta‐9‐THC feasible.
