What exactly is “dangerous machinery”? I frequently operate overhead cranes, lifting 0,5-5000 kilos. I also smoke pot. To be frank, I would be able to do my job somewhat high, but not drunk. Smoking a joint the day before work has minimal impact on my performance, I would argue it increases it because of a good nights sleep. Drinking alcohol on the other hand… I wonder if there has been any studies around marijuana impairment and vehicle operation?
