Pairwise Comparisons:

• Cocaine vs. Money: A PMC study, "Converging Effects of Cocaine Addiction and Sex on Neural Responses to Monetary Rewards" (2014), tested cocaine users with a monetary reward task during fMRI. It found cocaine dependence alters responses to money in the hippocampus, posterior cingulate, and frontal cortex, with sex differences (females showed lower activation). This suggests cocaine rewires reward sensitivity, even to non-drug stimuli like money.
• Money vs. Sex: The 2022 study noted above found money and erotic images both activate the OFC, but money uniquely engages frontopolar regions (planning/abstract thinking), while sex hits more primal reward zones harder.
• Cocaine vs. Sex: The 2015 PMC review cited an fMRI study where cocaine addicts showed limbic activation to both drug cues and sexual images, suggesting shared reward pathways.

Verdict

No triple-threat neuro test exists yet, but separate studies show money, cocaine, and sex all “flood” the brain’s reward system with dopamine, hitting overlapping regions (striatum, prefrontal cortex) with distinct flavors. Want me to mock up a hypothetical study design or dig deeper into one of these angles?
