Psychoactive drugs have different effects on different people. For me, caffeine is the drug that does not really do anything (higher doses in the 300mg+ range are definitely noticeable, but mostly by the physical side effects). Nicotine chewing gum produces a short-lasting mild stimulation (and I have to take a 4mg one, even though I am a non-smoker).
