Inside the brain, signals pass between cells called neurons. These signals become thoughts, memories, emotions and reactions to the world.

A signal is passed on when an electric charge travels through a neuron and releases chemicals called neurotransmitters.

Neurotransmitters flow across a gap called a synapse, causing the next neuron to fire and send the message, or stay dormant.

A change in neurotransmitters can influence our thoughts, moods, sensations and access to memory.

Using pot can result in those kinds of changes.
