All drugs certainly pose risks, some drugs may be 'riskier' than others but when it comes down to it the consequences resulting from the use of that drug depend greatly on personal experience. How you use the drug, how much and how often are major factors in the consequences of drug use.
It should be obvious to everybody that cocaine is addictive, almost as addictive as nicotine! My point in a previous thread was that the route of administration of substances such as cocaine also factors into the consequences resulting from its use. In this sense it is certainly not perfect, but we as users can perfect our patterns of use to minimize the consequences. Sounds to me like you're capable of doing it and other people are too.
