291: Is addiction more likely in sad people, Evo Psych in classrooms

In today's show, Dr. Lisle discusses:

1. Dear doctors, although addiction has been discussed extensively already im still trying to piece it together, thus would like your comments on the following: In a state of anxiety, stress and depression where we are getting negative esteem cues and dopamine levels are low, a substance that boosts dopamine can take one from 20 to say 80 on pleasure scale, whereas if you are content and calm that substance may take you from a 60 to say 70 or 80 which the brain doesnt recognise as a significant increment. does this mean that poeple who are sad are much more likely to get addicted to substances, much like the harvard study revealed?

2. Do you think it would be beneficial to include evolutionary psychology in school curriculums? At what age would children be able to grasp and understand these concepts? What impact would an awareness of our instinct to grade attractiveness and our genetic constraints of majorly being attracted to people 20% above and below ( depending on mating strategy) have on human relations and behaviour? Would it ultimately enrich life experiences?

3. My dad was a smoker in his twenties. my mom told me that he gave it up after the birth of my elder sister. growing up i remember that there was a sealed packet of cigarettes in a certain drawer that never moved, which my dad had kept to remind himself of the fact that he had quit and to practise willpower. after learning about channel factors this seems like a stupid decision in retrospect. what may be your comments on this?
