Memoirs of an Addicted Brain | A neuroscientist examines his former life on drugs.
I read his blog and there are some very interesting articles. This guy was an addict from age 16 to 30, then got clean and became a neuroscientist. He wrote his book to describe both the subjective and the physical things that go on in the brain with addiction.
I found the article within his blog on the tipping point extremely interesting.
Hope you all enjoy. I haven't read the book, but it looks like a good one.
