hello. what is responsible about consuming any legal intoxicant? tolerances to cannabis can be built without surpassing a level of system poisoning and death. tolerances allow cannabis users to perform at or near regular activity levels. choosing to do so is much more difficult. the fact remains that medical cannabis users are able to perform better at physical dexterity than they could without the aid, and the medicine will improve their performance. it neutralizes the negativity in their body, much alike the recreational user attains with a daily effort at a built level of tolerance. many people drive better on weed than without, and that they cannot is the myth to be busted.
