Abuse potential evaluation of inhalants.

Although inhalant abuse remains an important worldwide drug abuse problem, little is known about the relative abuse liability of specific inhalant compounds. This paper reviews approaches which might be used to investigate the abuse potential of inhalants in the laboratory, focusing primarily on animal studies. The principal approaches considered are inhalant self-administration and discrimination studies. A need is identified for further investigations of the abuse potential of inhalants to provide data which should be useful in shaping a more effective public health response to inhalant abuse.
