While depressants are the drugs which slow down the nervous system, stimulants are the ones which stimulate the central nervous system and speed up the messaging process. Mobilization of intracellular calcium and inhibition of specific phosphodiesterases only occur at high non-physiological concentration Different drugs, different effects. Even when we know the potential costs of using drugs, we may engage in them anyway because the pleasures of using the drugs are occurring right now, whereas the potential costs are abstract and occur in the future. 23(4), 564576.
