Inhalant use disorder is a form of substance use disorder in which individuals inhale fumes from everyday household or industrial products to achieve a mind-altering effect or “high.” This behavior may also be referred to as
sniffing,
huffing, or
bagging. Inhalants include a wide variety of items—more than a thousand different substances—that are not meant for human consumption, such as:
- Spray paint
- Paint thinner
- Gasoline
- Lighter fluid
- Nail polish remover
- Cleaning agents
- Oven cleaners
- Model glue
These substances act on the brain’s reward system in ways similar to other addictive drugs, reinforcing repeated use and increasing the risk of psychological and physical dependence. Over time, this compulsive behavior can take priority over responsibilities, relationships, and overall well-being.
