"There was some flower at a nearby dispensary that the budtender said would be perfectly fine to take during a tolerance break, it was 14.2% CBD and <2% THC, is the THC in this low enough or is no THC really the way to go during a t-break?"
It would seem that a low THC high CBD strain would be helpful during your THC break. While the science and research on cannabis is still emerging, from my understanding, CBD works by increasing our own natural cannabinoid levels (endocannabinoids), and does not need to interact directly with the CB1 and CB2 receptors. THC does directly stimulate these and other receptors, and thus having a lower level of THC present should help to reset any tolerance that has developed.
