An economon model of drug addiction

Negus (2024) built a new model called the economon. It treats drug use as a two-person operant economy.

The paper is pure theory. No new data. It maps how each hit traded between user and dealer changes the value of future hits for both people.

The model shows addiction is not inside one brain. It lives in the back-and-forth exchanges that keep both people dealing and using.

Change the reinforcers in that dyad—money, drugs, praise, escape—and the whole economy can shift.

Giallo et al. (2006) gives real numbers. They tested gamblers in and out of the casino. Sixteen out of twenty showed steeper delay discounting inside the venue. Context controls value just like the economon predicts.

Wulfert et al. (2006) shows the same logic in treatment. They added brief motivational talk to CBT. All nine gamblers finished therapy and six stayed clean one year. When the therapist became a stronger reinforcer, the client side of the dyad changed.

Embregts (2000) supplies the engine. That paper refined how establishing operations swing reinforcer power. Negus uses those EO rules to explain why the same dose costs more or less depending on the pair’s history.

Stop looking only at the client’s brain. Map the reinforcers flowing between user, dealer, friends, and clinic. Then pick one exchange you control—maybe pay for clean urine, or praise attendance—and watch the whole loop wobble. You just found a new leverage point.
