Danny Heifetz on theringer.com:
The trade comes less than a month after Gordon, who missed the first three weeks of training camp attending to his
mental and physical health, returned to the Browns. Gordon, who has
struggled with alcohol, Xanax, cocaine, marijuana, and codeine abuse in the past, was suspended from the league for multiple violations of the NFL’s substance abuse policy for more than 34 months between 2014 and his
return in 2017.
As for my claim that weed can be a gateway drug:
Is marijuana a gateway drug?
Doesn't mean that all, or even most people, who use it will graduate to hard drugs. But it does make some more susceptible to doing so. This guy is a junkie. An OD is definitely on the table. How likely that is, I have no idea. But it is far more likely in his case than for most NFL players.
