Earlier quoted context omitted.
Yes, I did. Nowhere does it say that. If you want to get a point of reference for what heroin might look like if it wasn't a street drug, oxycodone is quite similar yet distributed without the additives found on the street since it is manufactured by big pharma. Still, it is associated with respiratory depression.
I know it doesn't say that but it should be obvious most of them are due to poor IV administration. You don't need to administer heroin or morphine via IV. True, people occasionally OD on prescription medication, but it's usually as a rebound after having the prescription withdrawn and then finding more drugs.
The bottom line is, don't you think if they could sell more of this drug, they would? Opiates are a pretty terrible choice for an antidepressant for multiple reasons.
