Researchers analysed 40 regular edible cannabis users, testing their driving skills in a simulator before and after eating THC gummies. Higher doses led to poorer lane control, slower reactions and less consistent speed, while participants also reported feeling less able to drive. The participants’ blood tests came in below the legal thresholds for driving in Canada and New Zealand (5 ng/mL). The researchers say that edibles lead to lower peak blood THC concentrations than smoking, making it difficult to use blood THC levels alone to determine whether someone is actually impaired.
That is going to be wholly and completely individual. Even for the same person, tolerance changes A LOT between not smoking for a month and even just a smoke once in a while. Let alone the people that wake and bake every morning.
Some peoples’ blazed out of their mind is someone else’s morning routine when it comes to how much THC is in their system, and the tolerant potheads will perform infinitely better than a newbie or seldom smoker.
