AMA sets a daily allowance for alcohol.
What is the AMA’s daily allowance for marijuana?
No lower than their daily allowance for tobacco. What's your point?
Well, the death threshold of alcohol is about one quart or so, but there has never been a reported death from marijuana smoking, so I’d guess there is no daily allowance. Scientists estimate it would require smoking 40,000 joints in one siting to kill you, an impossible task.
The interesting thing about marijuana, it is somewhat self limiting. Countless times I have heard people say, “No more for me, I’ve had enough.” I’ve said it myself many times. You don’t hear that so much in a bar or at a party unless they are the designated driver.
Unlike alcohol which gets you drunker the more you drink, marijuana has a sort of plateau which you cannot overcome by smoking more of it. The quality of the pot seems to dictate how high you can get, not the amount you smoke. Regular smokers build a tolerance for the variety they are smoking. The only way to get that “first joint” buzz again is to change varieties or quit smoking for a few weeks.
