What does "huffing" refer to?

Huffing refers to the intentional inhalation of volatile substances or fumes, particularly from household products, to achieve a euphoric high. This practice is dangerous and can lead to severe health risks, including asphyxiation, organ damage, or sudden death due to toxicity. The main aspect of huffing is the deliberate inhalation of substances like glue, paint thinners, or aerosols, which can contain harmful chemicals.

While options that mention other drugs and methods may involve substance misuse, they do not align with the specific definition of huffing, which focuses on inhaling chemical vapors rather than snorting or consuming solid substances. Therefore, the understanding of huffing as inhaling poisonous fumes is essential in identifying its implications for health and safety.
