I'd like to ask the Minister why that evidence is inadmissible in the courts and what the purpose of removing that admissibility is. And does it cover not only people who are using substances but does that inadmissibility also extend to people who are supplying substances to others as well? I think the Minister in the chair may want to reflect on that, because there is a real issue here in New Zealand with illicit substances. It's not just the use but it's the supply and it's the peddling and it's the misery which gets caused by the people who peddle these substances to our young people and who cause enormous misery throughout society.
