We're currently investigating nasal pharmaceutical heroin, which is atomized into the nose. We're doing that because we have people who do not inject but are severely addicted. We also want to offer a reduced-risk option for receiving pharmaceutical heroin.
There is inhalable heroin, so-called smokable heroin, in the Netherlands. It works fine. It's another option. As I said, you need to have a range of substances, but you also need to have a range of routes of administration in order for treatment to reach maximum efficacy.
