This has been going on for a long time. About 10 years ago, my son's high school receiver here in Calgary who went on to junior football with the Calgary Colts practiced everyday with the Stamps as part of a development program they had at the time. He'd go to Stamps practice in the morning & then to Colts at night. that isn't being done anymore. He told my son back then that just about all the Stamps receivers he practiced with smoked weed & weren't concerned about being tested at all. I think a majority of players smoke weed now. So, makes no sense to test them.
