the use in the developing world is likely to be for treatment of leprosy, as thalidomide is very effective in treating lesions caused by leprosy. Thalidomide is also to be used to treatment of certain types of skin cnacers I think. I'd have no qualms about using the drug for these conditions to be honest. It's been more researched than any other "safe" drug such as paracetemol or ibuprofen, as research into it's possible uses has never stopped since the 60s. There is probably more info into the uses, applications and short or long term side affects of Thalidomide than most other drugs available today.
