SAN DIEGO - U.S. Marine Sergeant Sean Major is making a national push for approval to be the first active duty service member to use medical marijuana.

Major has received a physicians recommendation for medical cannabis use in October. He currently is prescribed more than 20 different pill variations.

The 25-year old wounded warrior has suffered four traumatic brain injuries in his seven years of service.

"I sustained my first traumatic brain injury in 2010 on the Pacific Rim… I’ve had one coming back from my deployment," said Major.

He's hoping the corps will hear him out and allow him to potentially be the first active member allowed to use the drug. He claims it would help with his sleeping habits and anxiety from PTSD.

"If I was missing an arm or a leg you could see that I was injured but with traumatic brain injury its almost like your computer is damaged," said Major.

Major says he began researching cannabis after seeing its effect on his veteran father, but stands strong on his stance for medical use and not recreation.

"You don’t need guys high running around defending this beautiful country I get that,” said Major.

Major also says he has drafted a nonprofit business plan, called EAS, to help other veterans with similar symptoms to be more self-sufficient.
