Please dont tell me how bad it is for me or how addictive, l already know. My question is about the effects it has on me. l have used it a few times, l am very infrequent. The few times l tried pipe tobacco it hit me very hard, and the one cigarette l tried caused me to almost pass-out and sharply impaired me. Is this normal in infrequent users? if so l cannot see how driving on it can be legal. l should also add every time l have used it it made me a bit nauseous. Is this normal or do l have some kind of allergy or sensitivity?

It sounds more like sensitivity rather than allergy. People respond to nicotine--or for that matter to any chemical -- in different ways. Listen to what your own body is trying to tell you.
