Probably a negative, since it shows that a person that was busted for growing weed is a huge danger to society. 

Really I have no idea, but I would suspect that if a persons past legal encounters could be used to deny their license application then the state control board will use that information to do just that. I would love to be proved wrong, I really would. But I guess I'm more than a little skeptical of the people who are on the control board. Bruce Schulte is a perfect example of someone who has a rather dishonest track record, but now he is one of the people that is shaping the "industry".
