There's a health concern in Dublin these days: an outbreak of botulism among heroin users.
There's another unspoken health problem associated with heroin: heroin causes diarrhea. For the life of me, I can't figure out why nobody mentions this when warning kids against drugs. All those movie scenes with heroin addicts on the floor next to the toilet are no coincidence, I suppose. You would have to be an addict if you are willing to get diarrhea to get high. Bleh! What could be a better buzz kill for "heroin chic" than a shot of someone having diarrhea at the same time. The cool would be gone instantly.
And suppose - just suppose - you live long enough to kick heroin. Then you are stuck with a lifetime of constipation! It's true! Who would want to be a heroin addict knowing that? I'm sure they're out there, of course. Hopefully you can smell them coming.
What's surprising about this botulism problem is how infrequently it occurs. Not even accounting for the dirty needles, heroin is a risk because people selling it to you will make their batch bigger by adding sugar or salt to it. Then they will sell it to you.
And why not? It's not like you're going to sue them.
CONFESSION: No, I am not a drug addict, nor have I ever been one. Maybe that's why I don't understand this.
