'Making drugs legal' is frequently miss-understood. Treating addiction as a public health problem by decriminalising addicts and personal posession while keeping the trade in drugs firmly illegal, as in Portugal and now Norway, looks like the way to go.
The recent changes to the law in Norway are widely reported as 'decriminalising drugs'. That is highly misleading. They have decriminalised drug use and personal possession, but the drugs trade itself is still criminal.
