Yes, I'd be pleased to answer that question, Madam Chair.
We have recently conducted a study within our NNADAP, the national native alcohol and drug abuse program, treatment centres to really look at the extent of prescription drug and polydrug use of people seeking treatment through these centres. We have found that about 30% of all people entering the treatment centres use opioids in addition to alcohol. Some could be using other types of illicit drugs as well. So it's about 30% of those.
Through the increased knowledge around prescription drugs and the increased evidence that there are actually possibilities of working with and treating prescription drug abuse as part of an overall treatment program, we are seeing an increase in the demand for prescription drug abuse treatment in the NNADAP treatment centres. We've had a very high success rate actually, Madam Chair.
In the research that we have done, we've found that 72% of the clients who entered those treatment programs with an opioid use problem left without an opioid use issue. They terminated the use. Of that small number of clients who didn't, almost 90% reduced the use.
