In Australia, 43% of people report having taken an illicit drug in their lifetime, including many prominent and respected figures.  Yet we still allow the ruination of an unlucky few caught by law enforcement.

Even if drug-taking is immoral, does it really need to be considered a crime? There are many activities that some people consider risky, unethical or undesirable, which are not illegal, such as gambling and adultery. While we may disapprove of them, we do not spend billions every year to criminalise them. Additionally, in a pluralistic society, there is no agreement on what constitutes immoral behaviour which is why law enforcement is ineffective in enforcing arbitrary moral dictates.
