Question

diacetyl is...

○ ...an ingredient in vape juice that is not good to inhale, but is not known to cause any illness.

○ ...an ingredient that the fda has said is unsafe in any form.

○ ...an ingredient that is considered safe in some foods to eat, but is not safe to inhale into the lungs.

○ ...an ingredient in vape juice that some people also eat for a buzz.

Explanation:

Diacetyl is a compound. It is used as a flavoring agent in some foods (like butter - flavored products) and is generally regarded as safe for consumption (when eaten). However, when it is inhaled (such as in vape juice), it can be harmful to the lungs and is associated with a serious lung disease called popcorn lung.

• The first option is incorrect because diacetyl is known to cause lung illness when inhaled.
• The second option is incorrect as the FDA has not stated it is unsafe in any form (it is safe in some food applications when ingested).
• The fourth option is incorrect as diacetyl is not consumed for a “buzz” and is not typically eaten as a substance people seek for a high.

Answer:

C. ...an ingredient that is considered safe in some foods to eat, but is not safe to inhale into the lungs.
