Graphic yes, but hopefully anyone who sees the effects, especially teenagers, will be scared off from any thoughts of doing any type of drug.
I personally have no pity for those people in the video (I saw it on youtube) because they made the choice to do drugs in the first place.
Just remember the parents who probably made the choice to have kids in a situation they shouldn't have. Most likely the parents were drug addicts or alcoholics in the prime of their using, they probably were born addicts to a substance before they even had a choice to make. The children probably weren't raised with a mother and father, ones who could at least raise them how a child needs to be.
I agree though, once you turn into an adult, you don't get to blame your past anymore. But we could go a long way to solving alcohol and drug addiction if we started coming down REAL hard on parents not raising their children. Having the addiction gene is not a guarantee of addition, it makes it much more likely, but it is not certain. The common truth in almost all addicts however, is their childhood, and how they are raised. Shocking I know, if you don't properly raise your children, they don't grow into a proper human being.
I just saw on TV a few days ago, a woman addicted to meth in prison, who had 9 children. Literally most of those children were in prison already, most addicted to meth as well. And guess what, she was pregnant with another child. And this is all perfectly legal. You can't build an addition on to your house with house without sticking your head up 3 or 4 separate government entities' rear-ends, but you can have as many children as you want, regardless if you're capable of raising them.
And Lusche, you hit the nail on the head with genetics. The alcohol gene has been proven to be a factor of quite a few genes, all adding their little touch.
Addiction is pretty easy to define, doing something that has negative consequences, and not stopping even after those consequences start negatively affecting your life.
Here's a little website that makes it pretty clear cut as to what's going on in the brain:
