This is exactly the problem. Some people can handle the nicotine and others can't.I've smoked tobaccos that threatened to sit me down that had no effect on others.
Have you eaten? How much did you smoke? Did you inhale?
Personally my sensitivity to nicotine is a constant challenge for me. For example, I love Irish Flake, but if I smoke too much at once I'll regret having picked up the pipe that day.
