A mind altering drug could offer a life without the addiction of heroin. [1]

First of all, the correct way to put it is to say “A brain altering drug could offer a life without the addiction of heroin”.
And secondly, how good is to decieve your self by using drugs to alter your will?
And what is more, can you REALLY alter your will?

Does it all come down to chemical reactions in the brain that we can control?
Or could it be that we are merely controlling an epiphenomenon, while the true problem still lies deeper inside?
