The Law of Unintended Consequences:
Now actual human beings in real pain will just have to suffer through it. Bite a stick, patients.
These laws inconvenience legitimate medical use. I had a friend way back in college who had a little vial of cocaine amongst his possessions. He also had a gaping cavity in a back molar that desperately needed to get repaired but he was waiting for his student health/dental insurance to kick in. In the meantime, after meals in the mess, he’d moisten his finger, jam a little coke down the rotten tooth hole, wait for it to kick it, and then brush it out best he could. He only used that coke for the above procedure and eventually saw a dentist.
