When my roomie went to Colob, he saw 2 girls trying to sneak H out of the country. One of the girls got a beating immediately (the one muling) and he told me she was hanged publicly, the other girl he never saw.
I wouldn't want to be in any of those prisons. If you're talking about smuggling drugs out of any of those countries, HR or not, you're not thinking straight. If you're talking just using, I'd assume if you use in the privacy of your own place you've got nothing to worry about.
