re: So if we legalize ALL drugs and end the "War on Drugs" today, how long....

I'll never agree to legalization of drugs. It's a recipe for disaster.

Don't take my word for it though

Footnotes

Medical and recreational marijuana legalization is destroying the health and social fabric of Colorado. Suicide, overdoses, ER visits, hospitalizations, and domestic and street violence due to cannabis are soaring while cannabis tax revenues are an anemic 0.98% of the 2021 state budget. Tax revenues are dwarfed by the Centennial State’s cost for law enforcement, automobile and industrial accidents, and increased school crime. Missouri must keep recreational marijuana from being legalized in 2022.

Do people push for legalization so they can do drugs?

I'm sure it's just a coincidence though /s
