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.
Oh it’s definitely worth studying, and I do not mean to defend “influenced” driving in any way. I only mean to point out any hard-line law is going to be very inadequate for THC.
Hopefully, there are other chemicals that can indicate a tolerance level, otherwise it’ll be near impossible to make an effective law that isn’t simply, “do not drive if under an influence.”. Which… wouldn’t be the worst thing from a safety point of view, but not so good from a, “let people do things that don’t harm others” PoV.
