Angrycat's Limerick Lamenting Fentanyl/Heroin mix

Fentanyl, which is 100X more powerful than morphine, has turned up in Western PA and other places in the Mid-Atlantic, resulting in many overdoses and several deaths. It goes under the names of Theraflu and Bud Ice. Don't do it.  Phillip S. Hoffman died of the regular kind of heroin, apparently, but don't do that either, obvs:

There's a new brand of smack: Theraflu
But you should find another drug to do
Because it's mixed with stuff
That makes survival tough
Avoid friends finding you dead and blue.
