i think it depends on a couple of factors...how much cocaine, how much steroids, i one goig to become addicted to the cocaine, is one going to take proper precautions with the steroids..
certainly, in most cases, steroids is less harmful. very few people get addicted to steroids in the way that people get addicted to cocaine. and even if one does become addicted to steroids, its a much cheaper addiction than coke, and you have to administer your drug a whole lot less more often. plus, a steroid addiction will give you physical improvements, where as coke will just make you wiry and thin.
