It seems crazy to legalize all drugs. How is that going to work with job drug tests. Can surgeons show up high on meth?
Decriminalization and legalization aren't the same thing.
With decriminalization, the drugs are still illegal but for example, you aren't gonna go to jail for possession. Instead you might get a fine or mandatory rehab or something.
Also even if it was legalized that doesn't mean that companies won't be able to have their own rules. It's perfectly legal to drink if you're over 21 but that doesn't mean jobs are gonna be cool with you showing up drunk
