While we all want to be happy, this story describes how sometimes things that are not good for us – like recreational drugs – can change our ability to feel happy.
- Our brain is designed to let you feel happiness whenever you do a behavior that helps you (or your species) get something you need to survive. The reward system is the part of the brain that allows you to feel happy.
- Recreational drugs activate the reward system, better, stronger and faster than any natural reinforcer – like food or water.
- Recreational drugs, definitely make you happy, but they change your brain. When your brain changes, normal reinforcers do not make you as happy as the drugs. Your brain becomes addicted.
