This is the medical marijuana ad CBS rejected for the Super Bowl, and it's incredibly moving and emotional.

The ad, produced by Acreage Holdings, a marijuana and cannabis investment firm, was willing to pay $5 million for the spot, but CBS turned it down ... because, we're told, they don't allow any marijuana ads on the air.

The ad profiles 3 people -- a boy who had hundreds of seizures a day that were not abated by traditional medicine, a man addicted to opioids, and a veteran who was in severe pain after his leg was amputated. All say medical marijuana made life livable.
