You get lightheaded because you aren't getting enough oxygen, eventually your body will get used to it, so you won't get that feeling anymore. However my advice to you is to quit now, since smoking is very bad for you, and it's and expensive and nasty habit to take up.
Take it as a sign and a blessing. Why keep doing something you know is deadly bad for you currently and future wise just because your friends are? Thats not bright at all. In the past five years ive known four people who died from lung cancer after smoking for years even though they quit several years ago. The last lady i knew died three months ago. She was the mother of a jr high age boy and a younger son who has Down syndrome. Shed quit smoking over five years ago and so had her husband. She died less than six months after being diagnosed with lung cancer. Why put so much effort into something that is eventually going to either kill you or put you on a oxygen tank one day? Be smart, not stupid!
Feel fortunate with all the time these people took to response to you and hopefully you listen to what we all think what is best for you .. Quit right now pls for your own good! Life is too short so live life to it's fullest in a good clean way. Take care.
moose you have no idea what you are doing to yourself...take some time to do a little research about the drug you are ingesting..the tobacco herb even in its natural state is a deadly plant...you mentioned you smoke when stressed but the reality is the nicotine (which is in tobacco) causes stimulation to your heart and nervous system..yes we all have to die but why set yourself up for a slow agonizing death which tobacco will surely cause...don't be fooled by these so called "natural" smokes...no matter what form tobacco is in it is deadly so do yourself a favor and quit now...there is nothing cool about yellow teeth, bad skin and the smell of cigarette smoke in your hair and clothes...seriously
I know this is a really late post but um I just happened to see this I am 17 turning 18 I smoke every once and a while and I feel totally light headed when I smoke as well but it makes me all giggly and stuff, and it feels kinda funny and I do breath right but that is the only problem that I have with smoking.
