Evidently it's in a lot of homes now and is making people sick. (This drywall was also imported to Vancouver so Canada's not immune.)
The problem is enormous. It’s estimated that as many as 100,000 homes across the country, built between 2004 and 2008, could have defective and potentially dangerous Chinese drywall.

From US Consumer Product Safety Commission:
Residents reported premature failures of central air conditioning system evaporator coils located indoors in the air handling unit and intermittent failure of appliances and/or electronic devices. Consumer Product Safety Commission (CSPC) staff inspections have noted corrosion of bare copper electrical wiring and the presence of sooty material on electrical wires (CPSC, 2009). Tarnishing and pitting of other metallic surfaces have also been observed in the affected homes in Florida and Louisiana by state and federal investigators.
Consumers in affected homes have reported various health-related symptoms including persistent coughs, bloody and runny noses, headaches, difficulty in breathing and irritated itchy eyes and skin. The most common symptoms reported among children (< 18 years of age) were respiratory infection, headache, dry cough, nosebleeds and eye irritation/redness. For both adults and children the most common“other” symptom reported was allergies/sinus/congestion. Many of these residents reported that the symptoms lessen or go away entirely when they leave their homes and return when they re-enter their homes (CPSC, 2009). In an informal survey of more than 400 callers to LADHH, the most common complaint reported was the presence of sulfur-like or other unusual odors.

I can see that USCPSC would test for sulfur and chemicals that could be causing the problems, but no one seems to realize that the problems might be from a chemical or additive nobody's thought to test the drywall for!
