As more U.S. states legalize cannabis (also known as marijuana) for medical and recreational use, increasing numbers of people are experimenting with it for pain relief. According to a new study published in JAMA Network Open, almost a third of patients with chronic pain reported using cannabis to manage it.

More than half of the 1,724 adults surveyed reported that using cannabis led them to decrease the use of pain medications, including prescription opioids and over-the-counter analgesics. Cannabis also effected the use of other non-drug related pain relief methods to various degrees: some people indicated that cannabis led them to turn less often to techniques that many clinical guidelines recommend as first-line therapies such as physical therapy and cognitive behavioral therapy, while others with chronic pain increased their use of such treatments.

The fact that patients report substituting cannabis for pain medications so much underscores the need for research on the benefits and risk of using cannabis for chronic pain."
