In terms of the effect on the heart, how different from exercise is the intake of stimulants? Both increase heartrate/bloodflow/respiration, so why shouldn’t amphetamines be a suitable alternative to running like a dog? I look ahead to a time when people shoot up instead of jogging to the pool for lap swim. People not judged by how many hours they put in at the gym but by how many bottles of pills they can swallow in a month.
