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.
This is sometimes called dichotomania (our obsession with splitting things into black and white bins, when reality is a spectrum), and it affects a lot of things, especially in medicine and law.
