""We basically show that cocaine is a disorder of the brain, which is a big step," said Ersche. "For a lot of people, it is still a moral issue and willpower has nothing to do with the brain."
So if something is connected with the brain, it cannot be a moral issue?! Willpower has nothing to do with the brain?!
I suppose Ersche will next discover that murder is not a moral issue: it turns out it's all about the victim's heart stopping!
