i see your point, and I’m not entirely sure either - amboss mentions “especially with cocaine” in https://next.amboss.com/us/article/wN0hWg?q=lidocaine#Z4e597a5573ddee2b3c1f06b0d0ceb97a ------- when it talks about arrhythmias oddly enough ---- maybe there’s some historical use of actual cocaine lol?
Cocaine is still used as a local anesthetic. Rejecting since no source given
