Question

within a year of the first vape devices being released, the world health organization released a warning that ______.
○ vaping devices were not useful in supporting quitting smoking
○ vaping was a relatively healthy way to stop smoking
○ cigarettes were definitely worse for you than vaping, and it was a good alternative
○ there was direct causation between vaping and lung cancer

Explanation:

To solve this, we analyze each option:

• Option 1: The World Health Organization (WHO) has research showing vaping devices are not effective for smoking cessation support.
• Option 2: Vaping is not a healthy way to stop smoking as vape products have harmful chemicals.
• Option 3: WHO does not endorse vaping as a good alternative to smoking, and comparing harm between cigarettes and vaping in this simplistic way is not accurate as both are harmful.
• Option 4: Direct causation between vaping and lung cancer is not established quickly within a year of vape devices' release with the evidence available then.

Answer:

A. vaping devices were not useful in supporting quitting smoking
