Congress Raises Tobacco Purchase Age From 18 To 21

President Trump signed a law raising the tobacco purchase age to 21, covering traditional and vape products. The American Lung Association supports it as a positive step. Bipartisan support includes Senators Romney and Kaine. Some states had already set similar age limits. The law will take effect in about nine months, with the FDA updating regulations within 180 days, followed by a 90-day implementation period.
