In your brain there are lots and lots of chemicals. Some of them make you feel happy and some of them make you feel sad. When your brain, which is like a giant computer, wants to tell you that you should feel happy it releases those chemicals and you feel happy! Soemtimes, the things we do can trick our brain into making us think we're happy, like marijuana. When you smoke marijuana your body gets very confused and releases all sorts of chemicals that affect the way you see and experience the world.
