Early research suggests that developing a tolerance for CBD is an opposite phenomenon to developing a tolerance for THC, involving what is known as a reverse tolerance. With reverse tolerance, continued use of CBD results in a continually lesser dose being needed to achieve the same effects over time. THC diminishes the effectiveness of receptors in the endocannabinoid system with repeated use. Conversely, over time, CBD promotes increased activity in these receptor cells so there is no breakdown of the interaction between CBD and the endocannabinoid system and the CBD can stay continually active without diminishing its own effectiveness. Many CBD users have reported using lower doses as time goes on to sustain their desired effects, proving to be both therapeutically and financially beneficial for them
