Its really very difficult to analyze human psychology and people often show highly ridiculous behaviors which had never been expected out of them.

A commoner often feels that successful tenure or distinctive performances are self motivated. It may be even the loneliness or professional boredom that prompt them to drug addiction. Professional hindrances or failures at times force them to get solace in drug addiction.

High level of aspirations are always good for a career, but when it goes beyond the control, people fail to succumb to the pressure. No concrete reasons can be concluded, but its the conglomerate that forces them. Never forget that they are the cream of the society and many others look up at them. They always enjoy that credibility.

It has been found that a film star has started drug addiction just because of failure in one movie.

A failure attempt of size zero also had provoked many to take drugs.

People become fanatic and drug addiction certainly fuels the fanaticism as you loss your consciousness at least temporarily.

When a public figure walks into the dark valley of drug addiction, people come to know about it, but who keeps track of the hundreds of such glamorous professionals who have also gone for drug addiction?

Under any circumstances drug addiction can not be justified. The desperation to find reasons for drug addiction can be the interest for the researchers, not for the people at large!
