I actually know little to nothing about cannabis
That's okay. Pretty common with boomers who got easily suckered by years of propaganda on the subject to not know much about it. I bet you watched Reefer Madness in high school correct?
So let me help you
Unlike alcohol, cannabis doesn't have a mostly linear relationship between the strength of the product, the consumption amount, and level of impairment. Everyone is unique and metabolizes cannabis differently. I have friends with Crohn's disease who consume 100 mg + a day and have zero impairment. You on the other hand could probably consume 5 mg and be planted, drooling on the couch asking for your mom. The brain and body can become mostly immune to the impairing effects of cannabis, especially when consumed consistently. A daily user is not the same as a daily drinker.
As for me? I don't drink while I ski. I actually haven't had a drink in a couple months at all. I do consume edibles fairly frequently. Mostly at home or seeing live music. If I'm impaired, I don't drive.
