A Tennessee lawmaker has proposed a constitutional amendment to legalize cannabis for medical purposes.

If passed, House Joint Resolution 742, filed by Rep. Jason Powell, would allow Tennesseans to access medical cannabis for approved medical conditions, such as cancer, epilepsy and multiple sclerosis, according to an ABC 24 report.

The proposal would levy a 4% sales tax on medical cannabis, the news outlet reported, with a portion of the revenue earmarked to support health care for military veterans.
