David Ford talks about a controversial subject coming up on the November ballot for voters in California—legalizing marijuana. It’s a subject that elicits strong emotions both pro and con.

Author of the book, Marijuana: Not Guilty As Charged, Ford lays out his argument for why marijuana should be legalized. One of the most compelling factors to consider is the tax revenue legalizing marijuana would bring to California.

Proposition 19, also known as the Regulate, Control and Tax Cannabis Act of 2010, is a California ballot proposition on the November 2, 2010 California statewide ballot. It legalizes various marijuana-related activities, allows local governments to regulate these activities, permits local governments to impose and collect marijuana-related fees and taxes, and authorizes various criminal and civil penalties. In March 2010 it qualified to be on the November statewide ballot.

A cottage industry supporting Prop 19 has grown in California. Paraphernalia and memorabilia, such as the type shown here, are available from various vendors hoping to capitalize on the trend.
