Maybe they do. Cigarettes are solving the problem of easy nicotine intake to release stress.
I think (not sure) a lot of successful new-media companies are solving the "low self-esteem" problem a lot of people cope with these days. They act like a drug.
But ofcourse a better way is to solve the source of the problems: remove stress from society, change culture in a way that we can become who we are (whole).
