From the interview:
…Why study the effects of LSD on the brain?
For brain researchers, studying how psychedelic drugs such as LSD alter the ‘normal’ brain state is a way to study the biological phenomenon that is consciousness. (Brain scans reveal how LSD affects consciousness)
The actual study is here: Neural correlates of the LSD experience revealed by multimodal neuroimaging.
Another article on this study can be found here: Brain scans show how LSD mimics mind of a baby.
Current scientific research confirms what many understood in the 1950s and 60s—that LSD used wisely often leads to good outcomes, increasing “creativity,” lessening depression, and removing addictive behaviors.
I know am a bit of a Buddhist heretic when I say that I am pretty sure the Buddha would have approved of or not disapproved of LSD. I say this because the fifth precept does not mention the abuse of any other drug but alcohol. For more on this topic see: Are We Misunderstanding The Fifth Precept?
