The Western Cape is "responsible" for 43% of the drug crime committed around the country. If drugs really do cause crime or lead to it then other crimes should similarly be raised, yet they are not. Res ipsa loquitur. Drugs doesn't cause crime, because IF it did the Western Cape's crime statistics would be far worse than they are.  (from SAPS)
