We did decide that every addict in this film, Warning: This Drug May Kill You, would be someone who started out with a prescription for an opioid from a doctor. The story that hadn't been told is that the vast majority - somewhere around 80 percent - of current heroin users began with an addiction to prescription opioids. So as much as people might want to look at this and say, 'Oh this is really a heroin problem,' yes, it is a heroin problem, and no one is saying differently, but it starts more often than not with a prescription.

In 1999, Purdue Pharma the maker of OxyContin went on a massive marketing campaign. Back then, prescription opioids were only used in extreme cases - post surgery, end of life care, cancer pain. We use a clip from an ad in the film where they had a doctor saying, "Less than 1 percent of people who use prescription opioid long-term will become addicted" - that changed the mindset of physicians across the country.

I want to make it clear, though, that I am not trying to say these are bad drugs. Opioid medications in the short term for severe pain are very effective. The problem is when they are used for long-term chronic pain. No one wants anyone to suffer and be in pain. But realize how addictive these drugs are and get off of them as quickly as you can. So 'Warning: This Drug May Kill You' is really more about educating people about these drugs so that everyone can make their own decision about their pain versus the addictive nature of these drugs.

Addiction is a brain disease - this isn't a moral failing - and we have got to stop looking at it that way.

Life expectancy for middle-aged white women has dropped dramatically over the past decade. Researchers didn't understand what was going on and so they were studying it and then very recently they realized it is driven by opioids. Why is that? They say now that it is because women are more likely to see a doctor for pain.

I hope 'Warning: This Drug May Kill You' documentary helps to show the humanity of the people who are struggling with the brain disease of addiction because that is what this is - this isn't about bad people, this is about good people who became addiction oftentimes in the process of being prescribed medication for pain.

It is unacceptable that the way we have treated people who have become addicted in the past is by throwing them in prison. It's appropriate that we're responding now by trying to get people the treatment they so desperately need. The racial divide here is absolutely unacceptable, and we have to do much better for all people who are addicted whether they are white, black, brown, any race - the humane way to respond to addiction is in a public health fashion and by getting people the help they need.
