Maybe not, I really have no idea how likely or unlikely it is.They can but it doesn't seem likely.
My first thought is, what's the downside? The NBA doesn't test for it, so they don't have the bad press of failed tests. I don't think NFL owners really care if the players smoke weed, and would rather have them playing than suspended. I don't know why they wouldn't do it.
