David Irving announced he is quitting football on Instagram Live Thursday.
While recording himself on live social media, Irving also began smoking marijuana and said, "It's much better than that opiate s---."
Last week, Irving was suspended indefinitely for violating the league's substance abuse policy. Irving previously served four-game suspensions to start 2017 and 2018 for also violating the substance abuse policy.
On Wednesday, Irving commented on Instagram about the prospect of the NFL changing its marijuana policy, according to Patrik Walker of 247 Sports.
"Well once they do that, give me a call," Irving wrote.
