Happy #420 or #weed day to those that celebrate. Here’s my #brain #drawing to mark the occasion. The user is exhaling a brain where in green are areas which are highly concentrated with the cannabinoid receptors #marijuana’s active ingredient binds too. These green areas house the functions of appetite, pain, memory, movement coordination, pleasure, sensory & time perception.
