Second question. If the claim that one of each three Afghans have problems with drugs is true, there is a fair statistical possibility that at least one of this men have skin blisters, kidney problems, chronically infected wounds that take ages to heal, lung problems, and poor health... just because a past history of drug abuse.

This particular set of symptoms can be found in people poisoned, but also consistently in any committed heroin addict all around the planet. Every single one of them.

This fact should be taken seriously to anybody trying to investigate this problem. There is a deafening background noise in the poor health variable just because the average level of health in the whole population was abysmal before, and this noise must be sorted out.

Maybe someone knows the answer.

But is there something unique about munitions used in Afghanistan or Ukraine vs those used in WW1/2 or Vietnam or Korean wars that are particularly more toxic or have increased duration of toxicity that would make crops unusable? I would have suspected the munitions to be similar enough to see the same effects.

Too many to count I'm afraid

Almost as many as the British during their heyday.

You just dont understand. It's the price of freedom! /s
