Sounds like Chandler had a bad trip on some Sherm, everybody has been there. No big deal.
Are there any synthetics on the banned substance list? Will he eat a 1 game suspension?I remember Kellen Winslow Jr. got up to some monkey business while high and he didn't receive a suspension, but he wasn't a patriot - at least not at the time.
If Jones really did take synthetic marijuana (who knows how accurate reporting is these days), unless they added it to the banned substance list the league should not be able to do anything.
It doesn't sound like it is on the banned substance list, it's not illegal, and he didn't get arrested. I do not believe the league has any legal right to access his medical records, he hasn't failed a drug test (as far as we know), and a first offense does not result in a suspension anyway.
If the league really wants to mess with the Pats, they can try the conduct detrimental angle but I am not sure that would get them anywhere. So IMO I don't think the league can do anything about it.
