Cannabis may be an effective alternative or adjunctive treatment for peripheral neuropathy, an often debilitating condition for which standard treatments often provide little relief. Most studies show moderately improved pain from inhaled cannabis use, but adverse effects such as impaired cognition and respiratory problems are common, especially at high doses. Data on the long-term safety of cannabis treatments are limited. Until risk-benefit profiles are better characterized, doctors in states where cannabis therapy is legal should recommend it for peripheral neuropathy only after careful consideration.
