From the Malaysia Star:
"The National Drug Agency (ADK) has, through its efforts, registered more than 300,000 addicts in its drug fight. However, just like the iceberg, the numbers are only what is seen above the surface. Some local studies have suggested there are an estimated three to four addicts who are not registered with the ADK for every one that is."

"There were an estimated 980000 hardcore heroin addicts in the United States in 1999, 50 percent more than the estimated 630000 hardcore addicts in 1992."

Using population figures of 280,000,000 for the US and 22,000,000 for Malaysia, the heroin addiction rate in Malaysia was about 4x higher than in the US. [latest numbers I could find for both countries]
So much for the "success" of the police state.
