In the United States, the use of asbestos in popcorn ceilings was effectively banned in 1977 by the EPA. While a complete ban on all asbestos-containing products in the US didn't happen until later, the EPA banned asbestos in spray-on surfacing materials, which included popcorn ceilings, in 1973 and expanded the ban in 1978. Although the ban was in place, manufacturers were allowed to use up existing stocks of asbestos-containing materials, so some homes built in the early 1980s might still have asbestos in their popcorn ceilings.
