You are so moronic.
To prove your case, you would need to bring up several studies that showed your position to be correct. So how about you start listing all the studies you've come across that shows that legalising drugs in western countries has increased drug use, and making them illegal has decreased usage. Once you do that, I'll see if I can find an example of a westernized country reducing the restrictions on drugs, and whether drug usage has gone up, down, or remained about the same.
