Inhalants are volatile substances that produce psychoactive effects when inhaled. Common inhalants include gases found in household products like aerosols and nitrates that dilate blood vessels. Inhalant use can cause both short-term effects like lack of coordination and long-term effects including paralysis or death. Inhalants are also considered gateway drugs that can lead to use of other more dangerous substances.
