Yes, it was Sweden. It would be very good for someone to do a study and present to your group. Of all countries, they are the only one that I'm aware of that experienced drug abuse increasing because they had very lax, very lenient policy. They became more restrictive in their policy, increased prevention efforts, increased treatment. They saw drug use go down. Then they relaxed, thinking that they had won over the situation, and started to get more lenient again, and they saw the drug use go back up again when they became more lenient. So then they became more restrictive again and saw it go back down again.
It's the only country I'm aware of where you actually saw a direct correlation between how restrictive the policy was and the problems that were a result of it. They twice proved that by being more restrictive they could reduce the problems.
