Yes of course. Or in most ecig styles you can get high, med, low and zero nicotine and quit altogether unless you still want the zero nicotine ecig for the mental standpoint of smoking. Pretty amazing product. I've helped a handful of people quit . Some don't want to quit bad enough and choose not to like them. They do give u a buzz and the nic hit if that's what your wanting. All that with no tar or horrible poisons. Much much better than tar cigs
