Menthol is reported to enhance the reinforcing actions of nicotine. My recent findings showed that menthol: 1) increases nicotine reward-like effects via central and sensory mechanisms, 2) alters nicotine-induced dopamine signaling in the nucleus accumbens, a brain region associated with nicotine reward. It has recently been reported that menthol enhances reward-like behavior of nicotine by potentiating nicotine-induced changes in nAChR function, nAChR upregulation, and dopamine neuron excitability. Further, mentholated cigarettes smoking, or oral mentholated nicotine products consumption, have increased in youth in the last two decades. Therefore, menthol may increase the risk ratio for nicotine addiction in youth. My latest data revealed that menthol increases nicotine consumption in a sex-, age- and concentration-dependent manner.
