A craving can appear even when somebody genuinely wants to stop drinking or using drugs.
That does not mean the person has secretly decided to return to substance use.
Cravings can arise because the brain has learned powerful associations between a substance and particular people, places, emotions, memories, routines and physical states.
A familiar road, payday, an argument, loneliness, a particular song, seeing drug paraphernalia or even feeling unusually happy can activate an urge before the person has consciously decided what to do.
Understanding this changes the recovery question from:
to:
This article explains the biology of cravings, why triggers become powerful, how dopamine and learning are involved, how stress and withdrawal can intensify urges, and how evidence-based treatment can reduce the chance that a craving becomes substance use.
A Craving Is a Signal — Not an Instruction
You can experience a powerful urge without automatically acting on it. Recovery treatment aims to create enough time, support and alternative responses for the brain to learn a different pattern.
How cravings develop, how to identify your strongest triggers, what to do during an urge, when medication may help, where naltrexone and long-acting naltrexone may fit, and what your personal craving-management roadmap should focus on next.

View Dr Fergus Law’s Clinical & Scientific Profile →What Is a Craving?
A craving is a strong desire, urge or pull toward using a substance.
It may feel primarily mental:
- “I can’t stop thinking about drinking.”
- “I keep imagining how it would feel to use.”
- “Just once would make this feeling go away.”
It may feel emotional:
- restlessness;
- irritability;
- anxiety;
- anticipation;
- excitement;
- frustration.
Or it may feel physical:
- tension;
- salivation;
- butterflies or tightness in the stomach;
- rapid heartbeat;
- restlessness;
- a sensation of needing something immediately.
Some are brief and manageable. Others can arrive repeatedly or feel overwhelming. Their pattern is often more useful than simply asking whether cravings exist.
Craving and Withdrawal Are Related — But They Are Not the Same Thing
Someone can therefore finish detoxification and still experience strong cue-driven cravings later.
Conversely, somebody early in recovery may be experiencing both withdrawal and conditioned cravings at the same time.
If substantial physical alcohol dependence is possible, withdrawal seizures, delirium or severe symptoms require medical risk assessment. Do not treat potentially dangerous withdrawal as “just a craving.”
How the Brain Learns to Connect Cues With Substance Use
The brain is constantly learning which events predict important outcomes.
If alcohol or another drug is repeatedly used in a particular situation, the brain begins connecting that situation with the expected effect.
The same process can occur with:
- certain friends;
- a dealer’s telephone number;
- being paid;
- a bottle or glass;
- driving through a familiar neighborhood;
- specific music;
- arguments;
- being alone;
- celebrations;
- particular times of day.
Eventually, the trigger itself can produce a learned physiological and emotional response before substance use occurs.
Dopamine, Motivation, Prediction and Craving
Dopamine is often described simply as the brain’s pleasure chemical.
That description is incomplete.
Dopamine is deeply involved in learning, motivation, salience, reward prediction and directing behavior toward important goals.
With repeated substance use, cues associated with the substance can become unusually important to the brain.
A cue may therefore produce a powerful “wanting” signal even when the person’s conscious judgment says:
Reward Learning
The brain learns which behaviors and environments predict important outcomes.
Cue Salience
Substance-related cues may capture attention disproportionately.
Motivation to Act
The learned cue can create an impulse to seek the substance.
Addiction does not result from one neurotransmitter being simply “too high” or “too low.” Dopamine is one part of a wider system involving learning, stress, memory, inhibitory control and other neurotransmitter systems.
Why a Trigger Can Produce Craving Before You Have Time to Think
Repeated pairings can turn a previously neutral cue into a substance-related signal.
Consider a person who repeatedly uses cocaine after receiving their salary.
Eventually:
The craving may then occur even if the person has been abstinent for weeks or months.
This is why treatment often involves changing the environment as well as changing thoughts.
External Triggers
External triggers are things in the environment that predict or remind the brain of previous substance use.
Early recovery often becomes easier when predictable high-risk exposure is reduced rather than repeatedly tested.
Internal Triggers
A craving can seem to appear “out of nowhere.”
Often, there was an internal trigger immediately beforehand.
Thoughts
Memories, fantasies, permission-giving thoughts or thoughts about relief.
Emotions
Anger, loneliness, anxiety, sadness, excitement or celebration.
Physical States
Pain, fatigue, tension, hunger, restlessness or poor sleep.
Memories
Remembering previous substance use or situations associated with it.
Cravings do not only occur during sadness or stress. Celebration, confidence, excitement and feeling that recovery is “under control” can also reactivate old patterns.
Stress, Anxiety and the Desire for Relief
Substance use does not always continue because somebody is chasing pleasure.
It may continue because the substance temporarily reduces:
- anxiety;
- emotional pain;
- withdrawal;
- loneliness;
- trauma-related distress;
- boredom;
- physical discomfort.
The brain then learns:
This is called negative reinforcement: the behavior becomes more likely because it temporarily removes an unpleasant state.
Treatment therefore needs to build alternative ways of responding to distress rather than simply telling somebody not to use.
Time, Place and Routine Triggers
Some craving patterns are highly predictable.
Finish Work
The brain has learned that work finishing predicts drinking.
Payday
Money availability becomes connected with drug use.
Alone at Home
Isolation and boredom become part of the using routine.
Celebration
Positive emotions and social cues trigger old associations.
When a trigger is predictable, the response can also be planned in advance.
Why Can a Craving Return After Months of Feeling Fine?
Recovery does not necessarily erase the old association between a cue and substance use.
Instead, the person builds new learning:
Old learned responses can sometimes become more noticeable again during stress, major life changes or exposure to a powerful cue.
A late craving therefore does not mean that months of recovery have disappeared.
Does Having a Craving Mean You Are About to Relapse?
No.
Research does show an association between craving, cue reactivity and later substance use.
But craving is not destiny.
The important question is what happens between the craving and the person’s next action.
Trigger → Craving → Automatic Use
Little time or structure exists between impulse and behavior.
Trigger → Craving → Plan → Alternative Action
Treatment creates additional responses before substance use occurs.
Recognize • Avoid • Cope
SAMHSA counseling guidance uses a practical framework for cravings: recognize, avoid and cope.
Recognize
Identify which people, places, emotions, thoughts and physical states are connected with your strongest urges.
Avoid
Reduce exposure to high-risk cues when practical, particularly during early recovery.
Cope
Develop specific responses for triggers that cannot be avoided.
Examples of Coping Responses
Urge Surfing: Learning to Experience a Craving Without Acting on It
One approach used in mindfulness-based relapse prevention is urge surfing.
Instead of trying to force the craving away or immediately obeying it, the person notices the urge as a changing experience.
The craving is imagined like a wave:
Mindfulness-Based Relapse Prevention: Urge Surfing
In this clinical demonstration, a practitioner guides a person through urge surfing as a practical strategy for responding to cannabis cravings. The same skill can be adapted within treatment for other cue-driven urges.
The goal is to become increasingly able to notice an urge, understand what triggered it and respond without automatically returning to substance use.
Build Your Craving Action Plan Before You Need It
Name the Trigger
“I am craving because I am alone, stressed and just passed the place where I used to buy alcohol.”
Change the Environment
Move away from the trigger when this can be done safely.
Delay the Decision
Do not make a permanent recovery decision during a temporary urge.
Contact Somebody
Use a pre-selected counselor, peer, family member or recovery contact.
Use a Coping Skill
Walk, breathe, urge surf, distract yourself or use another strategy practiced in treatment.
Record What Happened
The craving becomes useful information for improving the next plan.
Track the Pattern
A simple craving diary can record:
After one or two weeks, patterns often become much easier to see.
Alcohol Cravings: Behavioral Strategies and Medication
NIAAA describes alcohol urges as common during attempts to reduce or stop drinking and recommends identifying both external and internal triggers.
Behavioral treatment can help people:
- identify predictable drinking cues;
- change routines;
- avoid high-risk situations;
- develop refusal skills;
- learn alternative coping responses;
- strengthen social support.
Medication May Also Help
FDA-approved medication options for alcohol use disorder include naltrexone, acamprosate and disulfiram.
They work differently and are not appropriate for every patient.
Naltrexone can reduce the rewarding effects of alcohol and can reduce alcohol craving and heavy drinking in some patients.
Somebody with significant physical alcohol dependence may require medically supervised withdrawal management before focusing on longer-term craving prevention.
Opioid Cravings Need More Than Detoxification Alone
Opioid cravings may be driven by withdrawal, environmental cues, stress, conditioned learning or combinations of these factors.
CDC guidance states that detoxification alone is not recommended as treatment for opioid use disorder because return to use, overdose and overdose death remain important risks.
Methadone
Reduces opioid withdrawal and craving and has strong evidence for treatment retention and mortality reduction.
Buprenorphine
Reduces withdrawal and craving and is an established evidence-based OUD medication.
Naltrexone
Blocks opioid receptors and can support abstinence, but opioid-free preparation is required before initiation.
Anybody at meaningful opioid-overdose risk should have access to naloxone and know the overdose response plan. Naltrexone is not an emergency overdose-reversal medication.
Stimulant, Cannabis, Nicotine and Other Cravings
A craving-management strategy should not assume that one medication treats every substance-use disorder.
Cocaine & Methamphetamine
There is currently no FDA-approved medication for stimulant use disorder. Contingency management has the strongest evidence, often alongside CBT and other behavioral approaches.
Learned Cues Matter
Behavioral interventions can focus on trigger recognition, motivation, coping skills and changing established routines.
Cue + Withdrawal Treatment
Effective treatment can include behavioral support and FDA-approved smoking-cessation medications where appropriate.
The coping skill may be similar, but the medication and medical treatment strategy needs to match the actual disorder.
Can Naltrexone or a Naltrexone Implant Help With Cravings?
Sometimes — but the answer depends on what is causing the craving and which disorder is being treated.
Alcohol Use Disorder
Naltrexone is an established medication for alcohol use disorder and may reduce alcohol craving and the reinforcing effects associated with drinking.
Opioid Use Disorder
Naltrexone is an opioid antagonist.
By blocking opioid receptors, it reduces or blocks the expected opioid reward while sufficient antagonist activity is present.
Long-acting formulations can reduce the need for a person to make a daily medication decision.
However, a person who is still physically opioid-dependent must complete appropriate opioid-free preparation before naltrexone can safely begin.
What About a Naltrexone Implant?
Sustained-release naltrexone implants are designed to provide antagonist exposure for a much longer period than daily tablets.
The 2025 Cochrane review found that sustained-release naltrexone may reduce illicit opioid use compared with oral naltrexone or treatment as usual, but evidence is less certain when it is compared with opioid agonist treatments such as methadone or buprenorphine.
Naltrexone implants are not FDA-approved formulations in the United States. Product-specific duration, regulatory status and evidence therefore matter.
Medication Does Not Delete Learned Triggers
A familiar person, place, memory or emotion may still activate a learned response. This is why counseling and relapse-prevention work remain important even during long-acting medication treatment.
Where a Longer-Acting Strategy May Add Value
For a clinically appropriate patient with alcohol or opioid use disorder, a longer period of antagonist treatment may provide time to:
A naltrexone implant should not be presented as an established treatment for every type of craving. Its strongest clinical rationale relates to conditions in which naltrexone itself has relevant evidence, particularly opioid and alcohol use disorders.
The Goal Is Protected Recovery Time Plus Behavioral Change
DeBinge combines long-acting naltrexone treatment with professional counseling and follow-up rather than relying on medication alone.
An assessment should determine the substance involved, current physical dependence, withdrawal requirements, previous treatment, medical history and whether an antagonist strategy is appropriate.

1. Is craving a sign that treatment is failing?
Not necessarily. Cravings can occur during recovery because learned cues, stress and memories can remain active. The important question is how the person responds.
2. Does craving mean I secretly want to relapse?
No. A craving can occur automatically even when your conscious goal is to remain in recovery.
3. Is dopamine the cause of addiction?
Dopamine is important in reward learning, motivation and cue salience, but addiction involves multiple brain systems and environmental, behavioral and psychological factors.
4. What is a trigger?
A trigger is an internal or external cue associated with substance use or craving.
5. What are common external triggers?
People, places, objects, money, social media, music, smells, particular times of day and substance-related environments.
6. What are common internal triggers?
Anxiety, anger, loneliness, excitement, memories, pain, fatigue, boredom and substance-related thoughts.
7. Can positive emotions trigger cravings?
Yes. Celebrations, excitement and confidence can activate learned substance-use associations.
8. Why do I crave at the same time every day?
The time of day may have become part of a learned routine associated with previous substance use.
9. Why did a craving suddenly return after months?
Old cue associations can remain and may become noticeable again after stress or exposure to a powerful reminder.
10. How long does a craving last?
Duration varies. Many cravings are time-limited and change in intensity, but there is no universal countdown that applies to every person or every craving.
11. Should I avoid all triggers forever?
Not necessarily. Early recovery often benefits from reducing avoidable high-risk exposure while treatment builds stronger coping responses.
12. What is urge surfing?
It is a mindfulness-based strategy in which the person notices and observes a craving without automatically acting on it.
13. Can medication reduce cravings?
Yes, depending on the disorder. For example, medications can help alcohol and opioid use disorders, but medication choices differ by substance.
14. Does naltrexone reduce alcohol cravings?
Naltrexone can reduce alcohol craving and heavy drinking in some appropriately selected patients.
15. Does naltrexone stop every opioid craving?
No treatment guarantees elimination of every craving. Naltrexone blocks opioid receptors and can support abstinence, but learned cues and psychological triggers still need attention.
16. Can I start naltrexone while physically dependent on opioids?
No. Appropriate opioid-free preparation is required because naltrexone can precipitate severe opioid withdrawal if started too early.
17. Is a naltrexone implant FDA-approved in the United States?
No. The FDA-approved long-acting naltrexone formulation in the United States is extended-release intramuscular naltrexone.
18. Is naltrexone an established treatment for stimulant cravings?
No naltrexone implant is an established FDA-approved treatment for stimulant use disorder. Behavioral treatment, particularly contingency management, has the strongest evidence.
19. Do I still need counseling if medication reduces cravings?
Usually yes. Medication can change part of the biological environment, while counseling helps address triggers, coping, relationships, routines and recovery planning.
20. When should I seek professional help for cravings?
Seek help when cravings are frequent, intense, repeatedly lead to substance use, occur alongside withdrawal or overdose risk, or are becoming difficult to manage with your current plan.
The Goal Is Not to Depend on Willpower Every Time a Trigger Appears
An effective recovery plan identifies predictable triggers, changes the environment where possible, builds rehearsed coping responses and uses evidence-based medication when appropriate.
For people considering long-acting naltrexone, the medication should be understood as one part of a broader recovery strategy rather than a replacement for counseling and behavioral change.
