Each state has different medical marijuana laws, so it would depend on where you live what conditions qualify you to use medical marijuana. The National Conference of State Legislatures is a good resource for verifying accurate marijuana laws where you live. You could also check with your state Department of Health. Your physician is the most important resource though, for discussing medication changes. There are many recent studies that cite the benefits of using marijuana instead of opioids to treat pain, but it’s important to consider how it could interact with any other medications you may be taking.
