Is it ok to use medical marijuana?

There is no mention of marijuana in the Bible. Therefore, we can offer you no scriptures relating to marijuana or its use. 

Although marijuana is a drug and can be addictive, it does have some medical benefits. It is used to relieve pain, improve the well being of chemotherapy patients, help prevent some cancers from metastasizing, and, perhaps, slow the progress of Alzheimer’s, to name just a few. Medicinal marijuana is prescribed by a doctor and is usually in pill form. It is not to be smoked. 

If you are using marijuana for your medical conditions and not using it for recreational purposes then there should be no problem, providing your doctor monitors you.
