4. Certain pesticides sold over the counter
A number of chemical compounds once sold freely in hardware stores and supermarkets for home and garden use were later restricted or banned entirely once long-term health research caught up with usage.
5. Lawn darts
An actual children’s toy. Metal-tipped darts, thrown into the air, meant to land in a target on the ground. The injury reports eventually caught up with the design, and they quietly disappeared from toy aisles.
6. Asbestos in home insulation (in some regions, longer than expected)
Most people assume asbestos use ended decades earlier than it actually did in certain markets. Some older homes built more recently than commonly assumed still contain it, which is part of why renovation disclosure rules exist now.
7. Tanning bed use without any age restriction
Walk-in tanning salons with zero age verification were standard. Teenagers used them regularly with no parental consent required in many places — a policy that changed significantly once skin cancer research became harder to ignore.
