Medical marijuana is often used to treat conditions like chronic pain, multiple sclerosis, epilepsy, and Crohn's disease, as well as to manage the symptoms of chemotherapy like nausea and vomiting. If you're interested in incorporating marijuana into your life, there are a few different options to consider. You could smoke it, vape it, eat it in edibles form, apply it topically, or take it as a tincture. Just be sure to talk to your doctor about the potential risks and benefits first.
