Too bad that's absolute bullshit. Come on, you're trying to tell me that 50% of all people who use cocaine die from it. Not even the government has pulled a lie as big as that out their asses, and whoever you got that information from is the one who needs a bullet in the head.

I mean preventing kids from ingesting addictive substances is one thing but there are plenty of actual real life reasons not to do coke. I've smoked the crack and done the coke on multiple occassions as have several of my closests friends. If it were true that your risk of death after ingesting cocaine was 50% then I would think at least one of them would be dead by now. None of them are, nor have any ever come close.
Your real statistical risk of death as the result of cocaine is "Quite Low", 1:100,000. This is the same risk carried by the birth control pill. Compare this to the risk presented by alcohol which is 1:1,000.
Hell even the US governments "Cocaine Fact Sheet" available online states that
In rare instances, sudden death can occur on the first use of cocaine or unexpectedly thereafter.
