Final answer:
The corrected statement acknowledges that e-cigarettes are marketed as safer alternatives to tobacco, but their safety is challenged by some groups due to content of nicotine and harmful chemicals, and concerns about youth-targeted marketing.
Step-by-step explanation:
The corrected statement should read: E-cigarettes are marketed as safer than regular cigarettes; however, some groups challenge this claim. E-cigarettes are often advertised as a healthier alternative to tobacco cigarettes, even though they contain nicotine and potentially harmful chemicals like formaldehyde and diacetyl, which is linked to a serious lung condition known as 'popcorn lung'. Public concern is growing about the marketing strategies targeting youth with flavors like 'cotton candy' and 'alien blood', as e-cigarette use is on the rise among middle and high school students. These issues contribute to the debate on whether the FDA should regulate e-cigarettes as they do other tobacco products.
