Self-hypnosis or hypnosis is useful for breaking a bad habit, or for remembering something you might have forgotten. It does not make you smarter. What makes you smarter is using your brain - like exercising your muscles. Read as much as you can, and work brain-teasers like puzzles. Anything you do that makes you think in different ways and come up with new ideas will make you smarter.

No they cannot. Amphetamines only cause your brain to release endorphins that make you have a sense of feeling good but they do not make you smarter, they just destroy brain cells and make you do things you would not otherwise do.
