The main purpose of the Duster Inhalation Prevention Act is to regulate the sale and use of compressed air dusters to prevent their misuse as inhalants. This legislation aims to address the growing problem of inhalant abuse, particularly among young people, who may use these products to get high. Key provisions of the Act include the classification of certain chemicals found in aerosol dusters as hazardous substances. Specifically, the Consumer Product Safety Commission is tasked with declaring specific chemicals, like HFC-152a and HFC-134a, as hazardous.
