The Dallas Cowboys have always been known as a franchise with troubled players on its rosters. This offseason, the Cowboys have seen David Irving and Randy Gregory be suspended for substance abuse.

According to Irving, head coach Jason Garrett told him what he could do if he wanted to. Here's an excerpt from the article on USA Today.

“He told me I should just quit, smoke all the weed I want, the team didn’t need me,” Irving told USA TODAY Sports in a wide-ranging phone interview Thursday. “I’m a distraction to the team.

“He views marijuana as a drug, whereas I view it as a medicine. It’s not a good situation.”

This comes after the Cowboys' defensive end decided to quit football after being suspended for the third time over the last three seasons. All three instances involved him using marijuana.

There has always been an argument about whether marijuana should be legalized in the NFL. Regardless, the NFL has taken a stance to not permit the use of any marijuana at any time—even the offseason.

David Irving did decide to quit on an Instagram live session. During that broadcast, he mentioned that he didn't want to put himself through the rigors of the NFL any longer. He doesn't want to become addicted to pills and pain-killers due to the NFL pushing those outlets as the resources it recommends to overcome injuries.

Irving has decided to get involved in the marijuana business, selling his own products through Ghost Beverage, a marijuana-oriented company. This is a plot twist not just in a man's career, but in an evolving and complicated conversation about the substances athletes do — and don't — use.

The war on whether the NFL should allow marijuana will go on for for a very long time. Regardless of your view on it, it's unfortunate that a career has to end due to a player's personal situation.
