The problem is that you don't want more recreational drugs in your country. Alcohol is already a problem, so is tobacco, do we really want to add more?
It's naive to believe that legalizing drugs will damage drug lords. They will continue to sell different kind of drugs, because whatever you legalize, there's going to be a market for different kind of substances; and they will simply flood the market with cheaper, not health-approved, substances.
An example of it is illegal cigarettes smuggling caused by the rise of cigarettes prices.

There is an example of a country devastated by "soft" drugs, it's Djibouti (http://fr.wikipedia.org/wiki/Djibouti) with Khat (http://en.wikipedia.org/wiki/Khat).
You really don't want your whole workforce getting just enough to buy Khat and spend the day stoned or do you?
No silver bullet.
