What type of substances are classified as inhalants?

Inhalants are substances that produce chemical vapors which can be inhaled to induce psychoactive effects. The correct classification encompasses solvents, aerosols, gases, and nitrates. These substances are commonly found in everyday products such as glue, paint thinners, aerosol sprays, and certain nitrous oxide canisters used in cooking.

Inhalants are particularly concerning because their use can lead to immediate effects such as euphoria, dizziness, or hallucinations, but they also pose significant risks of long-term health issues, including damage to vital organs and potential for addiction. This contrasts with the other options, which do not typically produce psychoactive effects through inhalation or may even be designed for different uses entirely, thus not fitting the criteria for inhalants. For instance, aromatherapy oils and perfumes can be inhaled but are not categorized as inhalants due to their intended use and effects. Similarly, prescription medications and supplements usually have prescribed and controlled uses unrelated to inhalation, while natural plant extracts may be utilized for various therapeutic purposes but do not fall under the inhalant classification.
