But josepp, the whole point is that they just can't 'get a grip'. They would if they could. They're helpless in the face of the addiction. It's easy for you to step back from these things because you're lucky enough to have the kind of personality that takes control of your life. But others haven't got this in them. It isn't deliberate, they would probably give anything to be able to change. I've worked with addicts in prison, and I've seen how powerless they were to stop. I agree they wreck families and cause grief to their parents etc. But we can't judge them, as they can't help it.
