Hello I just smoked a cigarette for the first time today and smoked the whole thing but why did I vomit

Because your body is not used to nicotine. Quit smoking while you are ahead.

I might stop but how can u get my body used to the nicotine

Why in the world would you want to do that? Nicotine is a very addictive drug with some serious health consequences.

I know all that I mean it's not like I'm going to do it but I just want to know how I can get my body used to it

You get your body used to it by getting addicted to it. Just like crack, morphine, heroine.

I'm not going to ruin my chance to get in the military by ruining my lungs your right doc I shouldn't do it thinks for the help
