“VIENNA, 21 June (UN Information Service) - A survey on Drug Use in Afghanistan, issued today by the United Nations Office on Drugs and Crime (UNODC), shows that around one million Afghans (age 15-64) suffer from drug addiction. At eight per cent of the population, this rate is twice the global average.”
Now while I accept this doesn’t deal with other factors, even prima facie this suggests their claim is wildly inaccurate. and I encourage you to read the whole article, and delve beyond the facile hubris of religious claims everytime, indeed not just religious claims either. Theocracies limit freedoms, this doesn’t necessarily reduce all risky behaviours, and of course taking away people’s freedoms can itself be pernicious in many ways.
FYI and worthy of note, even were these hubristic claims true, they would not themselves represent any objective evidence for the exitance of any deity or anything supernatural; and totalitarian regimes are not always theistic, so it follows since the same freedoms could be removed in a secular regime, that religion is irrelevant to the claimed efficacy of those actions.
