Not a revelation. When I was in South Africa working with the government to build a better mortgage market, it was commonly know that the huge drug problem had Muslims at its source. While they don't use their own product, they are active in importing and distributing narcotics.
Bear in mind that many Muslims think that only Muslims are worthy. The rest of us are infidels and are of no interest. Of course, I know some Christians and Jews who think that anyone who think differently than them are not in God's grace and will not go to heaven.
Keep in mind there is a giant difference between:
"Bear in mind that many Muslims think that ONLY MUSLIMS ARE WORTHY. The rest of us are infidels and are of no interest."
And this:
"I know some Christians and Jews who think that anyone who think differently than them are not in God's grace and will not go to heaven"
I really do believe the difference is obvious but if you need help please let me know.
This is initially, but later they got caught into the drug's web. Check what happened in Pakistan. Once drug free, Pakistan swithced from being transit country, to being consumer..
