Well, first of all, thc is stored in fatty tissues, not your liver, second, the only thing that would be shitty about smoking joints for years is the carcinogens involved in the application method. Those problems go out the window with concentrates and vaporizing, and epecially topical treatments and edibles. So no. You would not feel worse for having smoked for a few years, other than the inevitable debris that comes with inhaling burned paper and plant material.
