For more than half a century, governments have aggressively pursued a disastrous “war on drugs” policy that criminalises a health problem and has only succeeded in making things worse. These policies are causing harm and are killing young people. It’s time for a complete re-think, but the Liberal and Labor parties don’t have the courage. The Greens are the only party with progressive and realistic policies to treat drug use as a health issue, not a criminal one.
