You could believe in drugs you could. You would want to have them always around and rely on them to get you out of a jam, rely on them to help you produce, rely on them for energy, rely on them for creativity, rely on them for calm. You could believe in drugs and demand they make you feel better when you are in pain or feel differently when you are sad, differently when you are upset. You could put faith into drugs. Or you could try and believe in yourself.
