I came across this image on the internet, which makes the claim, "There is a stronger link between childhood trauma and addiction, than there is between obesity and diabetes. Two thirds of addicts report being abused as children."
Doing some research to try and establish notability I found an interview from Johann Hari:
for every traumatic event that happens to a child, they’re two to four times more likely to grow up to be an injecting drug user—so, stronger link between childhood trauma and addiction than there is between obesity and diabetes. This is really powerful.
He cites an "Adverse Childhood Experiences Study."
So, the claims that have been made are:
1) There is a correlation inbetween childhood trauma and addiction
2) The correlation in betwen childhood trauma and addiction is stronger than the correlation in between diabetes and obesity
3) For every traumatic event that happens to a child, they're two to four times more likely to grow up to be an injecting drug user
4) Two-thirds of addicts report being abused as children
