Very, very low estimate, mostly due to omitting the casualties borne of the war on drugs.

You need to consider that governments promote the use of alcohol and tobacco--two deadly and addictive substances--while using violence and forfeiture laws to deter the use of far safer and less addictive substances like marijuana. So many of the deaths from emphysema, lung cancer, cirrhosis, heart disease are directly due to this policy?

Denying a person medical care is considered a war crime. Then, how are we to consider denying an entire society the benefits of medical research, purely on the grounds that it renders our drug policy in a bad light? Marijuana is still a schedule I drug in the U.S., prohibiting most if not all medical research into the drug. And yet, for a long time now we've had evidence that its medicinal value could be enormous. In 1973, for instance, the Medical College of Virginia completed a study that showed that THC administered to treat tumors in rats could either reduce the size of the tumor or in some cases remove the tumor entirely. Upon hearing of the study the federal government under Ford terminated the research. The Reagan administration moved to censor further consideration of the study and ordered all evidence it ever took place to be destroyed. Countless other studies met with the same fate. How many lives it that, potentially?

The overdose deaths that are primarily due to adulteration or no labeling, the violent deaths that result from turf wars between dealers that are a direct result of drugs being illegal, the suicides committed because of a drug policy that forbids chronic pain sufferers the medication necessary to relieve that pain... the list of the ways in which the war on drugs kills just goes on and on and on.

I think what you're going to find if you approach the issue with reason and compassion is that the 169,202,000 people you are now recognizing as having been killed by government are just the tip of the iceberg.

They see that they are championing what is easily the deadliest policy ever inflicted on humanity, and what do they do? Work hard to make it even deadlier.

I couldn't find America, But I thought it would be that way.
