Abstract:
1. A stable composition for rapid delivery by inhalation to the lungs, and subsequently to the bloodstream, the composition comprising a therapeutically effective amount of delta-9-tetrahydrocannabinol in a pharmaceutically-acceptable semiaqueous solvent consisting essentially of an alcohol, water and a glycol, in amounts sufficient (i) to aerosolize the composition to a mean mass median aerodynamic diameter in the range of from about 1 up to about 10 μM; (ii) to enhance partitioning by producing a stable clear solution near the solubility point of the delta-9-tetrahydrocannabinol; (iii) wherein the concentration of glycol is about 20% to about 65% of the solvent; and (iv) wherein the concentration of the alcohol is 20% to about 70% of the solvent.
