"I have done my fair share of drugs and as much fun as they were, the experience was nowhere near close to the peak moments of my life to date."
That's not what they are saying, though. They said that they've had the happiest moments in their life on it. It might not be the best moment of your life, but you'll be freaking happy about it. There is no real comparison between a chemically-induced happiness and the enriching happiness of big life moments, and the chemically induced happy is definitely its own happy. It makes those big life moments even happier in retrospect, more so in the moment with some lasting long-term effect.
