That's a myth. You don't make dumb decisions when you are high. You might contemplate them though.
Not sure why you are so adamant that Hanley smokes week when playing. I think it's a possibility, but really have no clue. He played so may years, he might have just been bored playing, smoking might have made it fun for him, he might have even hit better when smoking. Who knows, he might have talked Benni and Kelly and Vaz out of smoking before games, there is no way to tell.
It is interesting he's kicking it in the DR right now though. The dude is super set for money, no need to risk it. Hope we don't find out that he did other bad stuff. Would rather see him go out as a good guy.
