The Disease Called Drug Addiction

We criminalize drug addicts in this country. To Nora Volkow, director of the National Institute on Drug Abuse, that would be equivalent to putting someone with Parkinson’s in jail. Drug addiction is a disease that changes the chemistry of your brain, and makes you unable to kick the cravings. It all stems from dopamine, a powerful drug that controls pleasure and leads you to make decisions that aren’t truly benefitting your body.

Volkow walks us through the reasons that different drugs trigger addictions and why certain people are more prone to addiction than others. It’s not only about genetics- nurture plays a key role in making someone vulnerable to the disease.


She also launches into a discussion on the human’s propensity for food addictions, a relationship more complex than that of drugs. Is it possible to transfer a love of chocolate to a desire for lettuce and running? It’s more complicated than you think.

'Upstreamism': Your zip code affects your health as much as genetics

  • Patients from low-income neighborhoods are most at risk of negative health impacts.
  • Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.

  • Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
  • Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
  • It's also very dangerous to live with this blood type, as so few people have it.
