Sleeping Gas having effect on Godzilla

Probably, BTW it whas soma what made kong sleep in kingkong vs godzilla and cloroform in kingkong

Godzilla is a 350 foot beast.

Kong is only 40-50 feet tall

Godzilla is too big for it to have any effect on him.

It is not even sleeping gas but rather a powder form of the red berry juice that has narcotic effects on King Kong in the 1962 film.

No. and also which gas are you using? If its from the 2005 one it wasnt sleeping gas, Those were alcoholic narcrotics. Basically it was alcohol that they were throwing at him, Godzilla even if they somehow dropped some of it on him he wouldnt even flinch. The narcrotic alcohol would go through his nostrils into his stomach and his bodily fluids would instantly stop it.

Well no one knows how Godzilla anatomy works or how fast him metabolism is so there's no way to tell

What GODZILLASAURUS_REX said.

Kong is a 25ft tall gorilla that needed a lot of sleeping gas at the cost of dozens of casualties to put to rest. Godzilla's nervous system in comparison is so exponentially more vast and strong it's ridiculous. To get a powerful enough gas and get such a vast amount of it too would probably be more dangerous for us than Godzilla; it would kill a person with a single whiff (that's for sure) and with the amount needed, it'd probably reach nuclear explosion levels of range and affect the atmosphere, etc.

And even if we could do it, with Godzilla's healing factor and great size in mind, it'd probably just make him tired or sleep for a few minutes at most.

Final thing, if let's say Godzilla does go to sleep, what's our plan then? Carry all 90,000 tons of him away? Pfffffffft!

Overall, to quote Tony Stark;

"Not a great plan"

Actually, to everyone saying he's too big for it to work, Marvel Godzilla, who is significantly larger than Legendary Godzilla, was knocked out by chloroform gas in a comic I recently read (although they had to do it while he was sleeping in a cave, and even then he almost managed to get out into the open air before it took full effect), so it's not too inconceivable for such a thing to happen to him. However, the problem of what to actually do with him afterwards that Instinctive Gigan mentioned is totally legitimate; in the Marvel universe, S.H.E.I.L.D. was able to quickly transport him to a holding pen using a helicarrier, of course (though he easily escaped from it anyways), but in a more realistic world like that of the LPG soon-to-be series, you could probably transport him on a specialized train or other large land vehicle, but actually loading him on to it would be a monumental task in itself, the long journey with an indestrucible giant dinosaur onboard would be risky, and it would be very difficult to create any prison that could hold him for a significant amount of time unless they can constantly maintain a steady supply of gas to keep him asleep. Overall, it would be much more trouble than it's worth if it even could plausibly be done, especially considering that this Godzilla is really more helpful to humanity than anything else.

Well yeah, but that's old Marvel comicbook logic. Doesn't make any sense nowadays, I mean this was back when Stan Lee made Hulk out of gamma rays just cuz "it sounded cool". But if we're talking something like 2014 Godzilla and the military trying this method, no siree.
