The fact is, in areas where it has been legalized, the use of other drugs, illegal or not, declines significantly (along with crime in general). The biggest push back against it is by people that want to keep using it as a weapon to throw innocents in prison for decades, and by alcohol and pharmaceutical companies that know it will hurt their profits.

It’s significantly less addictive and less harmful to the user and the populace than alcohol. Especially if it’s ingested because now you aren’t harming your lungs with smoke or vapor. If it were legal in my state I would probably never drink again.
