The Iranian government has become pretty open about the drug problem in recent years. Opium use is a very traditional, cultural thing in Iran, so the government is actually more open about it than they are about some of the other ills in society. They just don't want to talk about things that might relate to a Western lifestyle even though they know that Iranians indulge. Because there is no real public life left in Iran - people go and have dinner and then everything retreats behind these Persian walls.
