Apart from the problems about how opioids are prescribed that were touched on in the article, one of the big problems with how opioids and other potentially addictive drugs are prescribed is that there's incredibly poor eduction around addiction, and a deep societal stigma against addiction.
Drug dependance and addiction isn't a moral or mental failing. It can (and does) happen to the most virtuous and intelligent people. Patients aren't educated to recognise the symptoms of beginning dependence and addiction, and if they do recognise it, they're reluctant to communicate this with their doctor for fear of being cut off entirely. Instead of being open and up front when they start to develop a problem, because of stigma and fear of being labelled a junkie, people will hide their behaviour, causing further problems. Also, because of the attached stigma, friends and family will often be reluctant to raise any concerns they have.
Your kind of response is exactly the kind of attitude and stigma that furthers the problem.

I tried googling for the odds of becoming addicted to those substances and couldn't readily find anything for either. Hopefully someone else sees this and can shed some light, because it would be interesting to me as well.
