The FDA has been cracking down on vaping products in recent years due to a growing concern about their safety. According to the FDA's website, millions of vaping products have been rejected for review as unsafe for human consumption. This means that many vaping products have been pulled from store shelves and cleared for use by the FDA.
The FDA's decision to target vaping products is largely due to concerns about their potential health risks. Some of these risks include nicotine addiction, flavorings that mimic food and beverages, and the use of certain chemicals such as formaldehyde and diacetyl.
