It's not surprising at all, really. If there's a drug out there that people can get easily which will, in turn, let them feel like they have a malady which excuses them from being an emotionally responsible human being, it will be procured and the so-called afflicted will beam with pride at having figured out how to shirk accountability for their actions- consciously or not. We're always looking for something for something to fall back on when we don't meet our own expectations. And while I don't feel that's the case for everyone on the drug- it has been shown to have an effect on the most severe cases of depression, after all- I think it's become far to widely prescribed for what amounts to a placebo; a sugary palliative to calm our disquiet nerves when we're too lazy to do so by actually taking care of ourselves.
