  14. Why Do Youth Start Smoking? Social Learning Theory • People can learn by observing others • This can be real-life observation or symbolic observation through movies and TV • Can learn how to do things (smoke/drink) • Can form expectations • Why people do things (stressed, upset, need to relax) • How you are supposed to respond to things (craving) • Consequences of behavior (reinforcing/punishing)

  19. Youth Are Especially Susceptible to Addiction • For some youth, symptoms of dependence develop • Before daily use begins • Within days after inhalation • There is no minimum requirement of number smoked, frequency, or duration of use!

  20. Youth Tobacco Addiction • Dependence is more severe if use begins in adolescence • Those who begin as teens are more likely to become dependent, use for more years, and use more heavily • Increased vulnerability to addiction may be due to still-developing brain Source: Sargent. (2003).

That First Puff . . . • The nicotine in one to two puffs occupies 50% of nicotinic receptors in the brain • A single dose increases the following: • Noradrenaline synthesis in the hippocampus • Neuronal potentiation can last for weeks • Meaning that neurons discharge action potentials at lower threshold
