Jason Mewes is a sweet, funny and friendly person. When he doesn't have half the coke in Colombia coursing through his veins and nervous system. Getting clean and putting his life in order were the best things that ever happened to him, even moreso than fame from being in Kevin's films.
Kevin's proud of and happy for the guy for what he's achieved and overcome and I don't blame him one bit. Recovery from chemical addiction has got to be rougher than a lot of us imagine, and Jay must have gone through his own private hell kicking his demons.
