Below is why I voted yes. It's taken form a comprehensive report by the ACLU. A simple possession arrest for a joint can change a life forever. That is not fair.

The report also finds that, on average, a Black person is 3.73 times more likely to be arrested for marijuana possession than a white person, even though Blacks and whites use marijuana at similar rates. Such racial disparities in marijuana possession arrests exist in all regions of the country, in counties large and small, urban and rural, wealthy and poor, and with large and small Black populations. Indeed, in over 96% of counties with more than 30,000 people in which at least 2% of the residents are Black, Blacks are arrested at higher rates than whites for marijuana possession.
