A DuPont study tried HFC-152a and HFC-134a on rats, dogs, and humans for time periods of up to three months with a followup examination 2 years with no adverse effects. LINK

That red line you drew could just be explained by market availability of the new Aerosol that convienently excludes the CFC equivalents which existed before and were banned.
