After smoking the initial cigarette, craving, withdrawal symptoms, and negative affect were lessened, and positive affect increased.

What happens when you smoke for the first time?
Many of the chemicals in cigarettes, like nicotine and cyanide, are poisons that can kill in high doses. The body is smart. It goes on the defense when it’s being poisoned. First-time smokers often feel pain or burning in their throat and lungs, and some even throw up the first few times they try tobacco.
What happens to your body when you smoke a cigarette?
Smoking raises your blood pressure and puts stress on your heart. Over time, stress on the heart can weaken it, making it less able to pump blood to other parts of your body. Carbon monoxide from inhaled cigarette smoke also contributes to a lack of oxygen, making the heart work even harder.
Why do I get light headed when I smoke a cigarette?
The dizziness you are experiencing while smoking is the effect it is having on your brain. When you stop smoking, nicotine is no longer triggering adrenaline to constrict blood flow. In the absence of inhaled carbon monoxide, there is more oxygen in the blood.
How long does one puff of a cigarette stay in your system?
Generally, nicotine leaves your blood 1-3 days after you stop using tobacco, and cotinine (something your body makes after nicotine enters it) will be gone after 1-10 days. Neither will show up in your urine after 3-4 days.
