GUEST  COMMENTARY-I am, and will remain, concerned that legalizing the sale of marijuana could be detrimental to the health and safety of vulnerable neighborhoods, leading to unintended consequences that cannot be offset by overblown estimates of the profit that commercialization might bring. Still, I recognize that Prop. 64 offers an opportunity to address at least some of the profound injustices perpetrated by the War on Drugs, especially against people of color.
