Is it normal ciggaretes make me sleepy

Yup, totally normal. Just one of the effects of nicotine. Don't smoke. It sucks.

I have had assailed blow smoke in my face, and I was so close to beating them senseless. I think smoking is about the most foul habit people can have. It stinks, their clothes smell, their hair smells. Even walking down the street if I am behind someone smoking, I will either cross the street or Get ahead of them. Growing up our parents would smoke in the car with Windows up since it was cold and rainy in winters here, and still is. We got bitched at for rolling down window for air. I would rather be around people snorting come or whatever they do. It doesn't fuck up my air that I breath.

Probably a lack of oxygen and circulation
