“I have to make sure I don't engage in conversations with people who don't abide by the rules of evidence.” - Dr. Carl Hart

New Book


I wrote this book to present a more realistic image of the typical drug user: a responsible professional who happens to use drugs in his pursuit of happiness. Also, I wanted to remind the public that no benevolent government should forbid autonomous adults from altering their consciousness, as long as it does not infringe on the rights of others.

After reading this book, I hope you will be less likely to vilify individuals merely because they use drugs. That thinking has led to an incalculable number of deaths and an enormous amount of suffering. I am confident that you will come away with an appreciation for the prodigious potential good derived from drug use and a deeper understanding of why so many responsible grown-ups engage in this behavior.

If the ideas expressed in this book are embraced, we can get on with the business of treating each other better and enjoying more meaningful and fulfilling lives. And isn’t that what we all want?
