Problematic substance use is a very complex health need. We're fully committed to implementing all pillars of the Canada health strategy, which includes the enforcement elements that Commissioner Kelly spoke about and harm reduction such as take-home naloxone and treatment.
Whether an offender is using or not while they're incarcerated, they can still have a substance misuse problem. Sometimes using a substance is indicative of access to a substance. You can have offenders who don't use while they're incarcerated, but still have a substance misuse problem on release. Substance misuse is very difficult to treat. I won't get into all the technicalities. Whether you're in a community treatment centre for the average Canadian or whether you're in our services, there are very low success rates for substance misuse treatment. We're certainly committed to doing our best.
To improve our approach—particularly in response to the opioid crisis, and in addition to the take-home naloxone and the nursing teaching—we're reviewing our entire opiate substitution therapy program to make sure we have all the supports, including the medical supports, the psychosocial supports, etc., so that we can have the best outcome possible for this disorder that is very difficult to treat.
For example, we've seen a doubling of the number of offenders on opiate substitution therapy in recent years. It used to be 400; it's now 800. We know that's a stabilizing factor. Offenders on opiate substitution will be more ready for release into the community.
