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.
