Common inhalants are substances that are breathed in to produce a psychoactive effect. The most common inhalants are AIR, which is the most widely used and readily available inhalant. AIR can be inhaled directly from the environment or through the use of a device such as a balloon or pipe. Inhaling AIR can produce a feeling of euphoria and relaxation, but it can also be dangerous if done in excess. Other common inhalants include nitrous oxide, aerosols, and solvents. Nitrous oxide is a gas that is often used in medical settings, while aerosols and solvents are liquids that are often found in household products. Inhaling these substances can produce a variety of effects, ranging from mild intoxication to unconsciousness.
