I wondered about this myself. I smoked throughout the 90s, but have been mostly nicotine free since. Recently I spent a few weeks experimenting with e-cigs to see if I could get the nicotine high that I remember enjoying without my body feeling like crap. No dice. Puffing on nice-tasting, pleasant smelling nicotine vapor still made my body feel like crap at times, just like it did when I smoked analog cigarettes. I didn't feel it in my lungs so much, but I did feel like my blood pressure was elevated and my heart was a bit fluttery, and once it gave me a rather bad headache. A few times it felt really nice, like I remembered, but mostly I felt like I was just chasing that feeling, and not really receiving the satisfaction I wanted. I canceled the experiment and gave my gear to a friend who still smoked analog cigarettes. He's quite happy having switched. He tells me his sense of smell has returned and his smokers cough is lessened. I noticed he no longer smells like an ashtray.
