What makes these people tick ?

I'm reading this morning's newpapers and all I see are stories about DRUGS !
What is it I'm missing here ?
Why are all these people ( young, mid aged & even old ! ) turning to substances which they must know will ultimately destroy them ,,  kill them even ?
Are their lives so awful, so unbearably bad that they see no choice ?
Or have they just too much money and not brains enough to make sensible choices as to how to use it ?

There's Ricky ( the Hit Man ) Hatton MBE ,,, boxer of some note, World Champion no less, seemingly nice enough, jovial wee guy, judging by his performances on such Tv shows as Jonathan Ross, Parky and even Loose women !.,., and now drugged up to the eyeballs & wasted, snorting cocaine live on uTube ! Probably lost his Boxing Licence .,., about to enter the infamous Rehab !!  Aye, Ricky ,, U- TUBE !!
Before him we had Joe Calzaghe CBE ,, another World Champ boxing legend .,.,another thoroughly nice, fun guy !
Why ? .,., Are the brains of these boxers suffering too much punishment in the ring ?

Then there was the houseful of Dopes in Falkirk ,, Smashed out of their minds on lethal concoctions of mixed drugs & booze. Two of them lay overdosed & dead in a bedroom while the "partying" went on ,, another young female "out of it" according to one of the partygoers was so ill that an ambulance was called .,.,
Too late alas for the bedroom pair who lay unnoticed by their " dazed & confused "so-called" friends !  The death toll may yet be three,,, four if you consider that the dead female was also pregnant ! 
What possessed her to risk her unborn child even if she had no respect for herself ?
Why ? Why? Why ?.,.,
What do we need to do as Human beings of the Earth to eradicate this woeful waste of people's brains, lives, and families ? There are times when I despair .,.,
Are we seeing the Fall of the Roman Empire all over again ,, but this time on a truly Grand Global scale ????
Maybe it is time to start again ???
