"More than 97% of drug addicts will be dead within 10 years, regardless of treatment received............ that's just a fact."

That's not a fact at all. It's either a gross error or a blatant lie.

Using statistics from the USA, they have approximately 23.5 million people addicted to either alcohol or drugs. Yet the combined total of American citizens who die due to alcohol and drugs is about 50,000 yearly. That's out of a total of 2.6 million deaths annually from all causes.

Were your claim correct, the USA would see deaths from addictions in the millions per year range. Your claim that Darwin had anything to say about drug addicts is likewise false. Unlike yourself, Darwin was a very compassionate man.
