There is a treatment for stimulant use disorder with better evidence behind it than most of what is offered, and you will struggle to find anywhere in America providing it.
The reasons are commercial and political. None of them is that it does not work.
What it is
Contingency management means attaching a consistent, immediate, verified reward to a specific behaviour — usually a negative drug test.
Someone tests negative, they receive something of modest value, straight away. Test positive, no reward, no penalty. Test negative again and the value often escalates, so a run of clean tests becomes worth protecting.
That is the whole thing. It looks almost insultingly simple next to psychotherapy.
Prendergast and colleagues (2006) pooled the trials in a meta-analysis and found it to be among the better-supported behavioural approaches in the field.
It is particularly important for stimulants — cocaine and methamphetamine — because unlike opioids and alcohol, there is no effective medication. Contingency management is the strongest tool available for a group of people who otherwise have very little.
Why the objection is wrong
The immediate reaction is usually: you’re paying addicts not to take drugs.
Consider that the effective principle is that immediate, certain, verified consequences change behaviour more reliably than delayed, uncertain ones. That is not a claim about addiction; it is a claim about behaviour generally, and it is not seriously disputed.
Then consider what we already accept. Physician health programmes attach a person’s medical licence to verified abstinence. Drug courts attach liberty to it. Both are contingency management with very high stakes, and neither attracts the objection — because the contingency is punitive rather than rewarding.
The discomfort is not about mechanism. It is about the direction of the incentive. We are comfortable removing something valuable and uncomfortable providing something valuable, for identical behaviour.
The physician data makes this concrete
The population with the best documented long-term outcomes in addiction medicine is physicians in state health programmes: McLellan and colleagues (2008) found 78.7% of 802 physicians licensed and working at five years.
DuPont and colleagues (2009) described the machinery: about five years of monitoring, roughly 48 random tests in the first year, a written contract setting out consequences, and — crucially — a positive test leading to more treatment rather than expulsion.
That is contingency management with a licence attached, run for five years. It is also the best-performing arrangement in the field.
So the model is not untested. It is running successfully, for doctors.
Why it is not available to everyone else
Money. The rewards cost something, and nobody reimburses them. A programme cannot bill an insurer for a $20 voucher. For decades federal rules also effectively capped the value of incentives so low that the approach was hobbled — thresholds set for anti-kickback reasons rather than clinical ones.
Optics. No administrator wants the headline about paying drug users.
It is not a product. There is nothing to license, no proprietary programme, no certification to sell. Nobody has a commercial interest in promoting it, which in American healthcare is close to fatal.
What a family can do with this
Ask whether any programme you are considering uses it, particularly for stimulants. The answer will usually be no, and the question itself tells you whether the person you are talking to knows the literature.
Understand the principle even where the programme is unavailable. The active ingredients — frequent verification, immediate response, a meaningful stake, escalating value for a sustained run — can be built into a private arrangement in a way they cannot be built into an insurance-funded one.
That is, in fact, most of what a well-designed private plan does. Agreed testing, someone who responds within days rather than at the next monthly review, and something concrete that a run of good weeks earns. Not because the person is being managed like a child, but because the physician data suggests it is the single most effective structure anyone has found.
And note who does have it. Doctors get five years of monitored, contingency-based care because a regulator requires it and a profession funds it. Almost everyone else gets thirty days. If you are paying privately, you are one of the few people in a position to buy the better model rather than the reimbursable one.
That is the argument behind how our case management work is structured, and it is borrowed wholesale from the physician programmes.
