title: Effects of cannabinoids and cocaine on the mitogen-induced transformations of lymphocytes of human and mouse origins.
abstract: The effects of delta 9-tetrahydrocannabinol (d9THC), delta 6-tetrahydrocannabinol (d6THC), and cocaine on the mitogen-induced transformations of lymphocytes of human and mouse origins were examined in an in vitro system. None of the three compounds is mitogenic in nature. The effects of the two components of marijuana on the mitogen-induced transformation are biphasic. Both compounds stimulated the lymphocyte transformation at low concentrations and inhibited mitogenesis at high concentrations. Cocaine, on the other hand, neither affected mitogen-induced lymphocyte transformations nor altered d9THC's transformation effects when both compounds were added together. Human lymphocytes and mouse splenocytes appeared to respond in similar patterns.
