This might be helpful: Nicotine is not cocaine, LSD, or morphine, or meth. Whatever you are looking for, you will not find it here.
Nicotine can provide an increase sense of awareness, allow thoughts to become more vivid and in general do things like helping Einstein focus long enough to envision how the universe operates. It will not make you high in the manner of the drugs listed above.
But it can make you feel sick to your stomach. Consider yourself fortunate that you can smoke heavier blends without getting knocked on your feet.
For the type of smoke you are looking for, I recommend the following blend: Salvia Divinorum. I promise you, you will find what you are looking for in it.
