Lofa Tatupu Says He'd Make NFL Comeback If League Legalized CBD

Lofa Tatupu says his body feels so good right now after using CBD ... he could make an NFL comeback TODAY -- and tells TMZ Sports he'd legit consider coming out of retirement if the league legalized it!!!

"If it's accepted in the next CBA," the former linebacker All-Pro says, "You might see a comeback -- I'll be 38 by then, but I don't care!"

Lofa was a superstar for the Seahawks from 2005 to 2010 ... earning 3 Pro Bowl selections and an All-Pro honor -- but injuries and concussions ultimately cut his NFL career short.

But, when we spoke with Tatupu earlier this week ... he says he's been taking CBD to cure his issues -- and he's never felt physically better in his life.

"I feel -- and I'm not lying -- better than my three Pro Bowl years," Tatupu says.

In fact, Lofa -- who's launched his own CBD company called ZoneIn CBD -- says he's feeling so good ... he thinks he could withstand the rigors of the NFL once again -- at nearly 40 years old!!!
