Cocaine imo is only good with alcohol, or opiates. Which is good mix, mixing them does not damage your heart, people die from speedballing because while on coke, they take too much heroin or other opiate, and when the coke wears off 20min's later, u discover youve done way too much dope, and POOFFFF! your dead. Back to the question, occasional coke use is only damaging to your shnoz. However, long term, or chronic use can cause thickining of the ventricle wall, in your heart, even in a matter of months, which will cause heart disease, the leading cause of death in Americans

A GOOD DRUG IS a TERRIBLE THING TO WASTE
