My take on it is if they claim to be so sure that cannabis can increase the risks of heart attacks due to an elevated heart rate, then they should be able to show us countless cases of people who had fatal heart attacks caused by cannabis. But they can't even show us one case where cannabis was listed as the cause of death. If there was even one case gov't officials and special interest groups like alcohol companies would be quite eager to plaster the deceased person's face on billboards or tv ads. And yes, they can also manipulate the facts to say whatever they want.
