Indeed, this is why states that have the death penalty for murder have no murder.

Oh wait...

You mean like how Singapore cleared their place from Opium ?

If people who sell Heroin die, then there will be less victims who will get addicted to such products.

Consumers who get addicted to Heroin are essentially poisoned (and nearly condemned to death) by their dealer.

It takes some time, but it would cleanup the whole situation, without putting the blame on regular consumers (who are eventually, step by step, pushed toward finding solutions to their addiction because sourcing the products is more and more difficult).

Yes, murders happen, even in peaceful societies. No matter if you have strong laws.

Now if you get rid of dealers, then, not only you have less drug issue, but you also have less murders due to less gang fights (as an interesting/bonus side-effect).

So, double benefit.

Singapore is a societal model that works for some people. It does not work for most, and certainly not for those who believe in North American culture.

This much repression and zero tolerance of drug usage percolates to the rest of society and other civil liberties that most people in the West would say they want full freedom to partake in. (Including soft drugs)
