marijuana cannabis back pain study vertanical.

A medication made from marijuana successfully reduced back pain in a new study. The results from a German drugmaker published Monday are the latest evidence that cannabis can be used to treat common forms of pain. The company plans to apply for approval in the European Union and eventually in the U.S. In the study of 800 patients, those receiving a liquid formulation of cannabis reported less pain, better sleep and improved physical function. Cannabis remains illegal under U.S. federal law, although most states have legalized the drug for either medical or recreational use. Many patients in state-sponsored medical marijuana programs report using the drug for pain, though quality research is limited.
