Are you suggesting that out of every 100 people who consume cocaine on a given night, 5 of them have a heart attack? Even DARE didn't lie that outrageously.
While it's likely a trigger to pre-existing condition it's not really safe at all like many try to paint. Same goes to most drugs really - OD's are very easy to do once you are on a binge.
I'm all in for recreational use, but these problems shouldn't be ignored. Keeping drugs illegal does not help, but having unmarked little baggies and candy all around little ones is very dangerous.
The heart attack stats are likely incorrect. An international WHO study on cocaine[0] concluded:
"A majority of health consequences may not be directly attributed to cocaine use. Cocaine often contributes to or exacerbates the conditions reported, rather than causing them."
"Few experts describe cocaine as invariably harmful to health. Cocaine-related problems are widely perceived to be more common and more severe for intensive, high-dosage users and very rare and much less severe for occasional, low-dosage users."
