Hello. Costochondritis is a common form of inflammation of the cartilage where ribs attach to the breastbone. Most cases of costochondritis are treated with OTC pain medications. Medicinal Cannabis is a great option for pain relief. Studies show that Medicinal Cannabis provides the best pain relief at a 1:1 CBD/THC ratio. Can CBD alone provide relief? Well, CBD alone is an anti-inflammatory, THC alone is an analgesic. CBD (only) may reduce the inflammation which may result in a decrease in pain, but not in comparison to the analgesic effects that THC can provide.
