Republican Gov. Chris Christie will now decide whether New Jersey residents with post-traumatic stress disorder can be treated with medical marijuana.

The Legislature on Monday approved a measure that allows marijuana to be used to treat PTSD if it's not treatable with conventional therapy.

Lawmakers say the measure is meant to help military veterans diagnosed with PTSD.

Marijuana is currently approved in New Jersey to treat multiple sclerosis, terminal cancer and muscular dystrophy, among other medical diseases. It's also approved for seizures and glaucoma if those conditions are resistant to conventional treatment.

The U.S. Senate passed an amendment in November that would allow Veterans Administration doctors to recommend medical marijuana to veterans in states where it's legal. The proposal failed to pass the House.
