The purpose of this study is to assess the effects of non-invasive vagus nerve stimulation (nNVS) on cognitive functioning in the users of e-cigarettes or vaping products. The investigators will use a digital wellness companion product (TRUVAGA™ device) that provides mild transcutaneous nVNS. The participants will be randomized to receive either a 2-min nNVS stimulation or control stimulation in the neck region followed by completion of three cognitive tests of attention and executive function.
