So in the NFL, where most players will have to have some form of pain killer and most players will endure a concussion, you are telling me you think opiods are the better solution as opposed to cannabis? Why should cannabis be banned by the NFL? Also, real science has actually shown cannabis is a neuroprotectant. It helps your brain. So in the NFL where concussions are prevalent, I think that should be looked at.
