There is a law called 'Karma', there's good karma and there's bad karma. It depends on which path we choose. If we abuse our bodies through drugs and substances, the law of bad karma applies. My point here is, whatever we do to our body the result will always be equal to the action we make. I've met a lot of people who suffered the consequences of their negative actions. An example is a man who died of liver cancer because of chronic alcoholism. These are the prices we have to pay for all the bad things we do to our bodies. Let's rethink things out before it's too late.
