Reduce harm
- The criminalization of marijuana use disproportionately harms young people and people of color, sponsors massive levels of violence and corruption, and fails to curb youth access.
Create jobs
- Legalizing and regulating marijuana will bring one of the nation's largest cash crops under the rule of law. This will create jobs and economic opportunities in the formal economy instead of the illicit market.
Save money
- Scarce law enforcement resources will be better used to ensure public safety while reducing corrections and court costs. State and local governments would acquire significant new sources of tax revenue from regulating marijuana
I could go on and on. 800 characters isn't long enough. There is no scientific or economic reason cannabis shouldn't be legal.
