Legalize marijuana, but...

Legalize marijuana and keep laws in place for employers to fire people who are high on the job, keep in place drug testing employees randomly. Would you want a drunk man handling your money at a cash register, let alone another substance not as fully studied by science? I am all for legalization, just make sure it is legal to possess THC levels that are found naturally in the world rather than manipulating THC levels for profits: https://youtu.be/SmqtPaMMVuY
Legalize Banking and enforce Banks to take marijuana money for deposit. Legalization might not be enough.
