Creatures of Habit is about how our habits are built, and how they control our lives, especially as teenagers. Today, we learn how to make new habits using habit loops, how to change pesky bad habits, and what science has in store for the future of human habit building.

This week on Brainstorms, we discuss America's favorite drug: marijuana. Your Brain on Pot examines the potential risks of marijuana to the teenage brain, and how marijuana stacks up compared to alcohol.

The DNA Trap explores how much of our brain is built by our genes. In the episode, we focus on addiction and mental illness, and how these two conditions are influenced by our genetic code that we inherit from our parents. Most importantly, we discuss what choices we can make as teenagers to live healthy lives, even if our brains are predisposed to illness and addiction.

In Episode 2, we investigate the true nature of peer pressure, social conformity, and the search for popularity based on the neurobiology of the teenage brain.

In Episode 1, we explore the effects that sex hormones have on the body and the brain, and introduce some major brain regions that define the teenage brain. As it turns out, puberty does not just reshape our bodies and crank up our sex drives- it changes the fundamental structures of our brains. In order to understand what it means to have a teenage brain, we must understand how sex hormones change its structure and functionality.
