This book was remarkably impressive. I had an impression that Tim Leary (due to his followers; it is another fact that most of them could not understand what he meant by "drop out") was a quack. I am happy to be proven wrong. Once I started reading Turn On, Tune In, Drop Out, I realized that Tim’s thoughts on drugs were similar to mine – take what you can learn while on drug and then implement those in your life. I have done that and successfully kicked the habit also.
