A few weeks ago, I talked on this podcast episode about whether THC can cause damage to the grey matter in your brain.

But, frankly, I spent very little time addressing the matter on that particular show, so in today's episode, I'm revisiting the topic of THC, brain damage, liver damage, myths about marijuana, CBD, smart drugs, nootropics and more with Dr. Andrew Hill, Lead Neuroscientist at truBrain, and one smart cookie.

During our discussion, you'll discover:

-Why left-handed people are more sensitive to chemical stimulants...

-The truth behind the evidence that THC can shrink the brain...

-The important differences between THC and CBD...

-How Dr. Hill can "reset" tolerance to marijuana using neurofeedback in his clinic...

-If there is a deleterious effect of THC on the liver or other organs...

-How to map your brain and change your brain using neurofeedback...

-Little known smart drug ingredients such as oxiracetam and centrophenoxine...

-And much more, including a killer giveaway at the end of the show!
