google it

You're putting a light in front of your eyes at night

What do you think

>>33209915

This. Did you think it was a side effect OP?

>>33209915

Wrong. Carbon Dioxide cause vasoconstriction. Less blood to the eyes means reduced vision.

Air Force 4MOX, I taught this shit in my night vision class.

>>33209990
Yeah, I thought it was more of a product of the nicotine they were talking about.

>>33210012
so we should vape instead.

well if you say so.

it decreases even more as you gain elevation if you smoke as well

>>33210035

strange that the military didn't study that pretty hard. Why have they let soldiers smoke then?

>>33210012
>>33210376
So would smoking weed have the same effect?

>>33210467
>dood weed lmao dood

>>33210467
I don't think so. Nicotine restricts blood flow whereas THC increases it.

>>33210481
dude, really

Inhaling smoke hurts your night vision both immediately and long-term.

It does so immediately because you are inhaling "air" with disproportionately high percentages of carbon dioxide and carbon monoxide and disproportionately low percentage of oxygen. This reduces your body to oxygenate itself and is basically mild hypoxia.

Long-term, you have all the particulate and heat from the smoke clogging or outright damaging/destroying the alveoli and cilia in the lungs and brachia, leading to a buildup of mucus and a reduction in the ability to get oxygen from the air into the blood ON TOP of the immediate effects.

This happens with ALL smoke, regardless of whether it's tobacco, weed, housefire, dog, etc.

In regards specifically to tobacco, you have added chemicals (arsenic, nicotine, the tar) that FURTHER increase the severity of the product. Nicotine is a vasoconstrictor, arsenic is a poison that is also a blood thinner, and the tar just clogs shit up.

>>33210467
See above.

>>33210438
They phased it out in the late 50s but also the amount of decreased vision isn't exactly crippling when you factor in you're going to get muzzle flash and adrenalin rush if you need to use your rifle.

If you were in a high risk area you would probably be told not to smoke because of snipers.

>>33210438
Because the behavioral benefits of not denying the source of a chemical and psychosomatic addiction outweigh the health detriments of smoking.

Also they'd get like, no recruits, if you couldn't smoke in the military.

Also also, you can't smoke on mission anyway.
