Nicotine and caffeine are not considered psychostimulants because they do not enhance locomotor behavior in rodents.cite journal |author=Sulzer D, Sonders MS, Poulsen NW, Galli A |title=Mechanisms of neurotransmitter release by amphetamines: a review |journal=Prog. Neurobiol. |volume=75 |issue=6 |pages=406–33 |year=2005 |pmid=15955613 |doi=10.1016/j.pneurobio.2005.04.003]

Psychostimulants are often potent modulators of dopamine signaling, often affecting the activity of monoamine transporters such as the dopamine transporter and vesicular monoamine transporters. [cite journal |author=Riddle EL, Fleckenstein AE, Hanson GR |title=Role of monoamine transporters in mediating psychostimulant effects |journal=The AAPS journal |volume=7 |issue=4 |pages=E847–51 |year=2005 |pmid=16594636 |doi=10.1208/aapsj070481]
