The NFL's new drug policy will include changes specific to marijuana and other recreational drugs.

A source told ESPN.com on Tuesday that the renegotiation of the drug policy, which has been going on since 2011 and includes testing for HGH, also will significantly increase the threshold for a positive marijuana test and reduce the punishments for violations involving that drug.

The source said the NFL's policy on marijuana is outdated, pointing out that WADA has a higher threshold for a positive test than the NFL currently does, and in need of updating.

The NFL has continued to insist that the commissioner have final say over discipline matters.

The changes are unlikely to impact the length of Josh Gordon's ban.
