Chicago Bears legend Jim McMahon says medical marijuana has been a "godsend" -- and has helped him get off the prescription pills he's been using to treat pain from his football career.
McMahon told the Chicago Tribune that he had been taking 100 Percocet pills a month to treat pain for his shoulders, neck and arms ... but switched over to weed when medical pot was approved in AZ (where he lives) in 2010.
"[The pills] were doing more harm than good," said Jim ... who also suffers from early onset dementia, headaches and depression.
"This medical marijuana has been a godsend. It relieves me of the pain -- or thinking about it, anyway."
