Final answer:
Inhalant abuse, involving the inhalation of chemical vapors to get high, is commonly referred to as huffing.
Step-by-step explanation:
Inhalant abuse is referred to as huffing. This term relates to the act of inhaling chemical vapors from substances such as household solvents, glues, and aerosols to achieve a state of intoxication. Unlike the opioids like heroin, which can be snorted, smoked, or injected for a euphoric effect, inhalants are abused differently. Heroin users may seek the intense euphoria by injecting directly into veins, even hiding track marks between fingers or toes. However, it's important to differentiate that, while some inhalants are used medically, such as halothane, enflurane, and isoflurane, these are halogen-containing anesthetic compounds and are not typically abused. These compounds are known for being less flammable than diethyl ether and are intended for controlled use in medical settings.
