US statistics are very skewed because marijuana is an “illegal drug” sold legally in most states. I did provide numbers for Asians in USA though, which was similar to Thais in Thailand.

Opium is at 3.3% by your number, which is comparable to the numbers I showed on Thailand.

We can both cherry pick data but USA has tried prohibition of various substances for over 100 years. Prohibition by itself caused more problems than it solved.
