Which of the following is NOT a consequence of nitrous oxide chronic abuse?

The choice indicating that increased sleep quality is not a consequence of chronic nitrous oxide abuse is accurate because nitrous oxide, when used recreationally or excessively, can disrupt normal sleep patterns and overall sleep architecture. Chronic abuse often leads to issues such as insomnia and disturbances in REM sleep, which are contrary to improved sleep quality.

In contrast, chronic use is associated with several adverse effects such as suffocation due to displacing oxygen, frostbite from the gas being stored in pressurized canisters, and peripheral neuropathy caused by vitamin B12 deficiency, which can result from prolonged nitrous oxide exposure. Each of these consequences stems from the physiological impacts nitrous oxide has on the body, but increased sleep quality does not align with the negative effects typically observed with its chronic misuse.
