David Irving -- the NFL player who quit over the league's marijuana policy -- says he's getting into the weed business ... and he's already brainstorming names for his new company.
Remember, the 25-year-old went to social media last week -- lit up a joint -- and announced he was leaving the Dallas Cowboys and retiring from pro football, despite the fact he's a pretty solid player.
So, what's next for Irving? A lot, actually.
Irving tells us he's doing everything from producing TV shows to working with FUBU ... and, of course, he's already planning to launch his own strain of marijuana.
