Whether this is even a question depends on where you live, because the United States has never had one rule. Massachusetts bans consumer fireworks outright, including novelties and sparklers. Illinois, Ohio and Vermont allow only wire or wood stick sparklers and novelties, though Ohio lets non-residents buy and remove them within 48 hours. Around forty states permit all or most consumer fireworks. The map has been moving steadily in one direction: Michigan legalised consumer fireworks when the governor signed the bill in December 2011, and New York followed in November 2014, permitting sparklers and novelties outside New York City within restricted sales windows. The federal line is drawn by the Consumer Product Safety Commission, which caps a consumer device at 500 grams of composition for multi-shot aerial cakes and 50 milligrams of flash powder in a firecracker. Most people answer a national question like this from personal experience of one local regime, and those experiences genuinely differ, so a 41-to-35 national split is partly a map problem.
