Also, California is home to the largest medical marijuana industry in America and following this one thing that everyone anticipated was a medical marijuana sales tax. The same has been finally introduced in the state which is expected to result in a 15% sales tax. As per reports, California would levy a 15 percent tax on all the medical marijuana sales in order to enforce new regulations and pay for state programs along with rehabilitation and parks under.
