The second-ranking Republican state senator is pushing to make medical marijuana legal in West Virginia.
Senate Majority Leader Mitch Carmichael filed a bill Monday to allow marijuana use for patients with debilitating health conditions.
The Jackson County Republican said he previously had opposed medical marijuana, but has since been convinced of its legitimate value as a therapeutic medicine.
The Compassionate Use Act for Medical Cannabis lists more than a dozen conditions that would warrant a marijuana prescription. Some include cancer, HIV and AIDS, Crohn's disease, Alzheimer's disease and Parkinson's disease.
They also include proneness to seizures, post-traumatic stress disorder, depression, anxiety and addiction to opiates or amphetamines.
Carmichael said he still opposes legalizing recreational marijuana.
Twenty-three states have comprehensive medical marijuana programs, according to the National Conference of State Legislatures.
