A particularly hazardous substance you may encounter is ______ or ______, which you can absorb through mucous membranes in mouth, nose, or eyes.

A particularly hazardous substance you may encounter is ______ or ______, which you can absorb through mucous membranes in mouth, nose, or eyes.

• A. cocaine, heroin
• B. fentanyl, carfentanil
• C. methamphetamine, LSD
• D. alcohol, nicotine

Answer: (B)

The correct choice is related to the highly potent opioids known as fentanyl and carfentanil. These substances are particularly hazardous due to their extreme potency and the fact that they can be absorbed through mucous membranes, which includes the mouth, nose, and eyes. This absorption route makes them especially dangerous, as even small amounts can lead to severe health consequences, including overdose and death. Fentanyl is significantly more potent than heroin, and carfentanil, which is primarily used as a tranquilizer for large animals, is even more potent than fentanyl. Because of this, first responders and others who may come into contact with these substances need to take extra precautions, as they can cause rapid and harmful effects with minimal exposure. In contrast, the other substances listed—cocaine, heroin, methamphetamine, LSD, alcohol, and nicotine—do pose risks but do not share the same level of immediacy and danger associated with the absorption routes and the toxic effects of fentanyl and carfentanil.
