I attended a presentation in the Summer of 2016 at the annual summer Colorado County Attorneys Association; the presentation was put on by one of the top attorneys in the CO Attorney General's Office who has been tasked with dealing with some of the legal ramifications of legalized pot. As part of the presentation, he showed a video depicting an experiment where three (or maybe four) Colorado citizens volunteered to get high and drive a test car around a set up course. They ranged in experience from "only smoked a few times" to "gets high every day." It was pretty sobering (pun intended) to watch how impaired they were after just a couple of hits. They all knew they were being tested for driving under the influence, so they were exceptionally careful to try to avoid the cones, but most of them were not able to react very quickly to pre-planned distractions. None of them reported "feeling" high or impaired until their second and third joints, but all of them made some pretty blatant driving mistakes that got worse and worse the higher they got. It was just a staged demonstration and not a scientific study, but it made an impression.
Interestingly (but perhaps not surprisingly), the chick who was a daily pot smoker had the best performance for the longest period of time, but even after she had 3 (maybe 4) joints, she was brushing the cones and appeared obviously impaired. My takeaway was that, like with alcohol, you can be more impaired than you think by a joint or 2, and that if you ingest enough to where you're feeling high, you're likely very impaired and ought to stay out from behind the wheel.
That seems like they should be absolutely blitzed smoking multiple joints especially given the supposed potency these days.
