Abstract

We have recently examined two patients who suffered from the adverse effects of intravenously injected marihuana. A review of the English literature identified only four previous case reports1-3 and mention of three others.4 Several recent studies5-8 have described the clinical effects from experimental injection of the purified marihuana components Δ9-tetrahydrocannabinol and 11-OH-Δ9-tetrahydrocannabinol; however, there are no controlled studies dealing with the clinical abnormalities induced by administration of crude marihuana extract. Our two patients shared the same broth and had almost identical clinical and laboratory findings. Their clinical course was similar to that described previously.1-3
