Enabling and alcohol / drug use.

"In most cases alcoholism is entirely dependent on an enabling influence. Usually that
influence is another well-intentioned person. The alcoholic who cannot perform his
responsibilities as a result of being impaired or recovering from a drunken stupor needs
someone to cover for them. The enabler generally has a vested interest whether economic or
familial in the alcoholic and is generally obligated or pressured to perpetuate the situation.
Unfortunately and unwittingly, the enabler merely postpones the inevitable day of reckoning.

It is very difficult for someone to willingly allow someone they love to crash, however, time
and again it has been demonstrated that allowing that crash to occur is the only thing that will work. At some point no amount of cover-up is possible and everything crashes".
