It would be grossly unusual for a single user. Grossly, extravagantly, extremely unusual.
I'd wager that less than 0.1% of all cannabis users approach 4g/day. They may binge up to 4g on their heaviest day of all time, but average far lower.
I would argue it's very unusual if only because the set of all people who can access 4oz/weed per month, and can afford the $1000-$2000/mo ($24,000/yr!) hobby is very small. Add up all of the trust fund kids with enough money, time and access and you have a tiny, tiny number of people.
An average heavy user can only afford that much weed if they're dealing and skimming, and supply and demand insists that not everyone can be a supplier. Even so, I'd wager the average heavy user chooses to use far, far, far less than 1oz every other week.
That brings me to the next point: to smoke 1 oz / weed every 2 weeks, you probably smoke at least once every waking hour.
So these HN rich kids who do it would almost assuredly require being high to do any work at all.
Personally, I don't want my engineers high as a kite 24/7 while working for me. Personal time is personal time, but on the clock non-stop smoking? But I guess people get away with it.
They do have a distinctive smell, though, especially once they are budding. If you aren't already growing other herbs and vegetables, then that might be undesirable.
Has there been any research into the effect of tolerance?
