Bittersweet symphony
Interesting question. The implicated assumption here is that cookies and meth do have something in common. Do they? Is the engagement of the brain reward system after intake what they have in common, or the other way around-- stress-induced changes to the reward system alters the risk for both eating and drug problems? Food is for survival. Meth is not. Meth interacts with dopamine transporters directly; cookies don't. (Cookie Monster's sad face)
Is stress and high accessibility the deadly combination for obesity and drug problems? Don't we need a 3*3 factorial design to test it out? I'd bet my money on accessibility.
Thoughts are welcome!
