> ..time-killing properties of opium or heroin, but with none of the likelihood of it stopping his heart
Opiates do not stop your heart. The notion that every single usage of opium or heroin is like a game of russian roulette, that might stop your heart, is fantasy. Opiates are actually quite safe, as drugs go. It's not until you take far too much or mix them that you are screwed. And that's true of any opiate, prescription or otherwise.
> Heroin kills, and OxyContin, unless badly mishandled, does not.
Basically not true; injected oxy requires no more 'mishandling' than heroin to kill. Both will happily shut down your respiratory system and kill you if you administer too much. Of course one could argue that the pharma is of a consistent manufacture and dosage, whereas one batch of too-strong street opiates could kill someone used to weaker stuff, but the author of this piece seems far too clueless about the subject to be making such distinctions.
Then we have comparison of marijuana's 'addictiveness' to that of opiates. The difference between psychological dependence and physical dependence is one of kind, not degree.
