Meditation has changed me profoundly as well. I started with 2 minutes and now I do at least 1 hour everyday. It actually all started with weed. From there to yoga, then meditation, then shrooms and finally spirituality and Nondualism. I not in control of anything anymore; that delusion has gone away. This journey of self discovery is turning out to be the greatest adventure of my life.
I can't even recognise the person I was 4 years ago. I've left that person far behind.
Real life never produces perfect examples. If consumption of psycho active substances in her/his life is unhealthy and dependent then I would also question any conclusions about that journey. But as far as the comment goes she/he doesn't provide any information on that. For many people drugs are entry point to deeper reflection and there is nothing wrong about that especially if one leaves the drugs behind at some point.
