Important question time, and ChatGPT wasn’t able to help here. A friend of mine was talking about some neighbors he had in an apartment building that smoked an impressive amount of weed, and that it changed the atmosphere.
For some reason I had immediately thought of “wow they replaced earth’s atmosphere with just weed smoke.”
So now for the question. How big would a joint have to be to accomplish this?
Big enough that the heat from it would probably set a lot of things on fire and as a result mess with the atmosphere in other ways
Also, given the average puff is about 35mL of smoke, and there's about 30 puffs average in a 0.5g joint, that gives us 1050mL of smoke in a 0.5g joint, or about 1.05kg (to unit transfer here) per 0.5g joint. There's an estimate of 5.1480x1018kg (think five quintillion) of fluid in the atmosphere. So that would be an increase by a factor of about 4.9 quintillion. Converting the joint weight to kg gives you 0.0005kg per joint. So you multiply those.
Your joint would have to be 2.451429x1015kg of weed. 2.45 quadrillion kilos. For reference, the weight of all humans on this earth combined is about 390 billion kilograms.
I'm tired lmao someone check my work I may be stupid
