The Legend: When you use LSD the right and left hemispheres of your brain separate.
Status: False
Analysis:
The brain is separated into two halves, the right and left cerebral hemispheres, which are connected by a thick bundle of nerves called the corpus callosum. This nerve bundle bridges the two sides of your brain and allows the two halves of your brain to communicate with each other. In cases of extreme epilepsy, the corpus callosum has been severed surgically. There are also a few cases where the corpus callosum has been severed by trauma. There is not a single case of the brain "splitting" or the corpus callosum being severed due to LSD use.
The brain also cannot separate and then reconnect 8 hours later when the LSD is gone, it just doesn't have that kind of rejuvenative abilities. And no, severing the corpus callosum isn't something that "might" have happened to you but you're not sure. Believe me, if it happened you would know it.
