I never really liked this term when it came to marijuana. IMO doesn't apply the way it sounds. In my experience there were very few things I couldn't do at the same performance level as when I was sober. Could I be an anomaly? Probably, but I also know A LOT of people who dabble in a little "hangover medicine" as we call it and it is about a 50/50 split of people who function fine and succeed in life vs those who I feel wouldn't succeed anyway and use marijauna as their clutch
