In addition, there was a recent study showing that harsh penalties and rates of drug use are not correlated. http://www.theguardian.com/society/2014/oct/30/punitive-drug... If you think that particular countries have unusually low rates of use, then you may be just wrong because of misreporting, or it could be to do with other societal factors (eg. children having to live at home longer with parents because of social norms or housing issues).
You should also remember that by far the most widely used illegal drug is cannabis (93% in the UK), and it's almost impossible to die from cannabis. About the only way I can think of is if a block of it drops on you from a smuggler's aircraft. So just looking at deaths from drug use isn't so interesting. There are other ways that drugs are both productive and enjoyable, and can be damaging.
All the Asian countries I mentioned have more draconian drug laws, less crime and less drug usage rates than the European ones I mentioned (along with the United States).
It's easy to dismiss my argument by calling them corrupt and their statistics misleading. It's another thing to actually refute my argument with facts and figures, which you haven't done.
