Psychosis and neurosis are such broad terms. Any narcotic or substance or even regular food and medicine that you take in excess will cause that.
You could also make broad correlations from the lifestyles, behaviors, and personalities of the people who take these substances and probably conclude they have some sort of psychosis or neurosis themselves.
