His work covers marijuana gardening, law, social policy, and culture, and his books have sold over two million copies combined.

His best-selling titles include Marijuana Grower’s Handbook, Medical Marijuana Handbook, Why Marijuana Should Be Legal, the Big Book of Buds series, and Marijuana Garden Saver, among others.

Rosenthal views marijuana law as a crucial social issue. He serves as an expert witness on federal and state cultivation trials, and is active in promoting and developing civil regulation. He also teaches classes at Oaksterdam University and gives related seminars.

After California passed Proposition 215 in 1996, Rosenthal was deputized by the City of Oakland to cultivate marijuana for patients. In 2003 he was prosecuted by the federal government in a high-profile case.

Green Aid: The Medical Marijuana Legal Defense and Education Fund was formed to support Ed’s trial. Now Ed serves as Green Aid’s Executive Director. Green Aid works to fund and publicize precedent-setting marijuana trials, and is currently focused on the most vulnerable casualties in the war on drugs: families.
