Kamala Harris supports marijuana legalization: It "gives a lot of people joy"

Why it matters: In detailing her advocacy, Harris, who admitted in the interview that she had smoked a joint "a long time ago," joins a growing field of Democrats who back marijuana legalization.

• Last May, Harris championed the Marijuana Justice Act introduced by Sen. Cory Booker, another 2020 Democratic presidential candidate.
• Harris' comments follow those of Booker's, who kicked off his campaign earlier this month, calling for legalizing marijuana as a critical component of criminal justice reform.
• Marijuana is presently legal in 10 states, while 33 states have legalized the substance for medicinal use and several additional states are considering legalization in 2019.
