Consumers resort to drug trafficking five times less, according to a study, but police sources say seizures of illegal marijuana have remained at the same level.

RIO DE JANEIRO, BRAZIL - The government of Uruguay has seen a sharp reduction in illegal marijuana trafficking in the first four years after legalization under state control.

However, according to the police, the seizures have remained relatively constant since the adoption of this pioneering measure worldwide.

The contradiction, which still has no clear explanation, exemplifies the difficulties in gauging the real progress of marijuana drug trafficking.
