In many states now, chronic pain is a qualifying medical condition, allowing you to be treated by medical marijuana.

Many patients with chronic or severe pain enjoy smoking or vaporizing their cannabis supply when possible. Since these intake methods provide a more rapid effect in the body, they offer a quick way to experience relief. If the ability to minimize discomfort rapidly is vital to your treatment, consider discussing this intake method with your physician in greater depth. Cannabis can also be ingested via capsules, tablets, tinctures and edibles. For localized pain treatment, consider using a topical, such as an ointment or cream, instead. You’ll experience targeted pain relief in the specific portion of your body where pain is occurring.
