"The sleeping pill Halcion, already banned in Britain and several other countries, is coming under renewed scrutiny in the US.
The Food and Drug Administration's Advisory Committee on Psychopharmacologic Drugs was briefed last week on a new Institute of Medicine report which argues that taking Halcion as recommended causes no serious ill effects. But the report also notes that many Americans are prescribed much higher doses of the drug by their doctors, and the IOM wants the FDA to check for possible problems caused by the drug.British regulators banned Halcion in 1991 over fears that it could cause psychiatric disturbances."
You can buy Halcion online, without prescription, here, here, here... I guess that's enough
I guess that FDA is a regulatory agency to approve and make drugs remain as long as possible at US market.
Unfortunately many countries with no regulation uses FDA standards giving the agency a great power over the global market.
