I don’t know much about her, but directly from the wiki:

The rate at which Harris’s office prosecuted marijuana crimes was higher than the rate under Hallinan, but the number of defendants sentenced to state prison for such offenses was substantially lower.[76] Prosecutions for low-level marijuana offenses were rare under Harris, and her office had a policy of not pursuing jail time for marijuana possession offenses.[76]

It sounds like her position on weed is not exactly what people are painting it as. At least these comments make it seem much worse than it is according to the wiki.
