He is what will probably happen if you start smoking...
First, you will try a cigarette. You will cough, your lungs will hurt, and you might have the feeling like you wanna puke. However, you will also get a feeling like all of your blood is rushing to your head. It will feel mildly euphoric, and you will have a little more clarity of thinking. I think of it as taking a very low dose of Percocet or other prescription pain killer, only enough to feel the effects but to not be a zombie.
Next, that feeling will go away, and you will light up again. Might be after a few hours or it might be a month down the road. After you light, you realize that it doesn't hurt so much to inhale. It's actually quite pleasurable. And that nicotine rush....WOW!!!! Hit you like a ton of bricks. Now you feel amazing! You're thinking clearly, you feel great, life is on the up and up.
Fast forward a little bit. You now smoke 3 cigarettes a day. Smoking one still feels good, but it's a little harder to feel that high. You explain to yourself that you will only have 3 a day. You don't want to be full on addicted. Fact is, it's already too late.
Before long, 3 cigarettes dont give you the high anymore, so you do 4. 4 becomes 5. You start smoking right after you get out of bed in the morning. Next thing you know, you're smoking a half pack a day. You smoke more when you are stressed. You start smoking after a drink at the bar, after a few rounds of video games, during your break at work, on your way home. You start to realize that now you don't get a nicotine high, but you smoke so you don't have cravings.
On top of all of this, you start going through body changes. You are more irritable if you haven't smoked for a while. Food/drinks don't taste as good. Your fingers smell. You smell. Your level of fitness drops (can't run as far, cant push as much, ect) and even moderate cardio makes you short of breath. You cough more. Your libido drops a bit. Your overall health drops, but you continue because you are addicted.
Finally, you decide to quit. However, patches, gum, and lozenges are total shit. You may try the prescription medication route. It works, but you start having vivid dreams and difficulty discerning reality from the dream world (I did). You may even consider suicide because it feels as if you are going insane. You quit prescriptions and go back to the cancer stick. Btw, cold turkey and the lollypop methods don't work.
Smoking may seem harmless at first. But honestly, its a very slippery slope. I have been smoking for almost 5 years now. Yeah, I admit that sometimes I love it, and that it helps reduce stress (or my mind had reasoned that it does). But I also hate it. I currently have an e-cig on order so I can try to quit, because smoking a pack a day is hard on the body and extremely hard on the wallet.
TL;DR Smoking is bad, mmkay?
