Monica M Arnold et al.
Neuropharmacology, 85, 293-304 (2014-06-08)
Tobacco use is the leading cause of preventable death. Although the health risks are well known, cessation rates remain low. Whereas behavioral and neuroanatomical studies on tobacco addiction conventionally use nicotine, there is evidence that other constituents, such as monoamine

Pharmacology, biochemistry, and behavior, 198, 173041-173041 (2020-09-15)
Identifying novel constituents that contribute to tobacco addiction is essential for developing more effective treatments and informing FDA regulation of tobacco products. While preclinical data indicate that monoamine oxidase (MAO) inhibitors can have abuse liability or potentiate the addiction-related effects
