Question

Quizplus · Accepted Answer

Phencyclidine (PCP) is known to enhance the psychoactive effects of inhalants. It acts as an NMDA receptor antagonist, which enhances glutamate neurotransmission and potentiates the effects of other drugs. Methcathinone, a psychostimulant, can also potentiate the effects of inhalants but is not as specific in its mechanism of action. Buspirone, an anxiolytic, and bupropion, a nicotine cessation treatment and antidepressant, do not have mechanisms of action that would specifically enhance the effects of inhalants.
