In these pages, author John-Mark Miravalle explores, through a Catholic lens, the phenomenon of chemical mood alteration and reflects on our feelings of pleasure and suffering and how they relate to the rest of our humanity.

With the help of these edifying pages, you'll learn what effect the uses of particular substances typically have on your ability to regulate your feelings and cultivate an emotional life that leads to happiness and fulfillment over time.
