1. Tolerance Development and Escalating Drug Use
One of the foundational signs of substance use disorder is developing tolerance. Tolerance occurs when your body adapts to a substance, requiring you to use larger amounts or more frequently to achieve the same effect you once felt with a smaller dose.
This biological adaptation is a critical indicator that the body is becoming physically dependent. As tolerance builds, a person’s substance use often escalates in a dangerous cycle. This is not a sign of moral weakness; it is a physiological response that often signals a developing SUD.
- Example: Someone who used to feel relaxed after one glass of wine now needs a full bottle to achieve the same feeling.
- Example: A person prescribed 10mg of a painkiller finds it no longer works and begins taking 30mg to get relief.
2. Withdrawal Symptoms Upon Cessation
Experiencing withdrawal symptoms when substance use is stopped or reduced is a powerful sign of physical dependence. These symptoms are the body's reaction as it struggles to function without the substance it has adapted to.
The presence of withdrawal shows the body now requires the substance to maintain equilibrium. The severity and type of symptoms vary depending on the substance, duration of use, and individual health factors. For substances like alcohol and benzodiazepines, withdrawal can be life-threatening without medical supervision.
- Alcohol: Tremors (shakes), sweating, anxiety, and nausea may occur.
- Opioids: Intense flu-like symptoms, including body aches, vomiting, and anxiety.
- Stimulants: A "crash" marked by severe depression, fatigue, and intense cravings. For more details, see the Adderall withdrawal symptoms timeline and treatment.
3. Neglect of Responsibilities and Social Withdrawal
A consistent neglect of major responsibilities is a telling behavioral sign. As substance use becomes the central focus, obligations related to work, school, and family are often pushed aside.
This shift demonstrates the compulsive nature of the disorder, which rewires priorities in the brain. An individual may also isolate themselves from friends and family or pull away from hobbies they once enjoyed. This pattern of neglecting duties and withdrawing from social connections is a significant red flag.

- Professional Life: Missing deadlines, showing up late, or a noticeable drop in job performance.
- Academic Life: A student’s grades drop, they stop attending classes, or they withdraw from campus activities.
- Family and Home: Missing children’s school events, forgetting to pay bills, or failing to manage basic home duties.
4. Deceptive Behavior and Secretiveness
As a substance use disorder progresses, a person often becomes secretive to protect their ability to use. They might lie about their whereabouts, finances, or activities to conceal the extent of their substance consumption.
This behavior is often a defense mechanism driven by shame, fear of judgment, or the need to continue using without interference. This pattern of dishonesty erodes trust and isolates the individual, creating a painful barrier between them and their support system. Recognizing this secrecy as a symptom of the disorder, rather than a character flaw, is key.
- Example: Hiding alcohol or pills in a car, office, or around the house.
- Example: Lying about where money is going while secretly spending it on drugs.
- Example: Inventing stories about being sick to explain away missed work caused by substance use.
5. Continued Use Despite Negative Consequences
One of the core signs of a substance use disorder is continuing to use drugs or alcohol despite facing significant negative consequences. When a person cannot stop their use even when it is causing harm to their health, relationships, or career, it signals a loss of control.
This behavior is a primary symptom of a complex brain disorder. The substance has rewired the brain's reward circuits, making the drive to use incredibly powerful, even in the face of devastating outcomes.
- Health: Continuing to drink heavily after a doctor diagnoses alcohol-related liver damage.
- Family: Persisting in substance use despite facing the loss of child custody.
- Legal: Continuing to use after being arrested for a DUI or possession.
- Professional: Being fired from a job due to substance use but being unable to stop the behavior.
This pattern highlights the severity of the disorder. If you are concerned about the health risks of stimulant use, you can learn more about Adderall overdose symptoms.
6. Mood Swings and Irritability
A significant psychological sign of an SUD involves dramatic shifts in mood and emotional stability. Chronic substance use impacts brain chemistry, particularly neurotransmitters that regulate mood, like dopamine and serotonin.
A person may experience intense irritability, unprovoked anger, persistent anxiety, or rapid emotional swings that seem uncharacteristic. These changes can strain relationships and create a chaotic environment. Recognizing these mood swings as a symptom of a deeper issue is a key step in understanding the disorder.
- Alcohol: An easygoing person becomes verbally aggressive after drinking.
- Stimulants: A person cycles from euphoric to withdrawn, paranoid, and depressed.
- Opioids: During withdrawal, a person may express hopelessness or suicidal thoughts.
7. Neglected Physical Appearance and Health Decline
A noticeable decline in physical appearance and personal hygiene is a visible sign of an SUD. When obtaining and using a substance becomes the central focus, self-care routines like showering, grooming, and eating well are often abandoned.
This physical deterioration can manifest as rapid weight changes, poor skin health, or dental problems. These outward signs often reflect severe internal distress and the physiological damage the substance is causing.
- Alcohol: Puffy, reddish complexion and significant weight changes.
- Stimulants: Dramatic weight loss, severe dental decay, and skin sores.
- Opioids: Pinpoint pupils, visible track marks, and a perpetually drowsy appearance.
8. Cravings and Preoccupation with the Substance
Intense psychological cravings and a mental preoccupation with getting and using the substance are powerful signs of an SUD. Cravings are intrusive urges to use that can dominate a person’s thoughts and make it nearly impossible to focus on anything else.
This mental obsession diverts significant time and energy. A person’s day can revolve around planning how to obtain the substance, using it, and recovering from its effects. This preoccupation often comes at the expense of responsibilities at work, school, or home.

- Example: An employee is unable to concentrate on tasks because they are constantly thinking about their next opportunity to use.
- Example: An individual spends hours each day calling contacts and arranging funds to obtain their substance of choice.
9. Unsuccessful Attempts to Cut Down or Control Use
A defining characteristic of an SUD is a persistent desire to reduce use, followed by repeated unsuccessful attempts. An individual may genuinely want to quit but finds themselves unable to follow through.
This loss of control is not a reflection of willpower; it is a core symptom of the disorder. This cycle can create intense feelings of shame, guilt, and hopelessness. Recognizing these unsuccessful efforts as a clinical sign highlights the need for professional support.
- Alcohol: Swearing off drinking after a binge but returning to heavy use after a stressful event.
- Prescription Opioids: Trying to self-taper pain medication but taking more than planned to manage cravings.
- Cannabis: Deciding to only use on weekends but returning to daily use within a short period.
If you observe this pattern, it is a clear sign that professional help is needed. Structured treatment programs in Newport Beach can provide the tools and medical supervision that willpower alone cannot.
10. Legal Problems and Risk-Taking Behavior
Substance use disorder often leads to impaired judgment and an increase in risk-taking behavior. As the priority shifts to obtaining and using substances, individuals may engage in activities they would never consider otherwise, often resulting in serious legal consequences.
The accumulation of legal issues, from driving under the influence (DUI) to more severe charges, is a critical red flag. These events often serve as a wake-up call, demonstrating the urgent need for professional intervention.
- DUI: Being arrested for driving under the influence in Orange County.
- Drug-Related Charges: Being charged with possession of a controlled substance.
- Crimes to Fund Use: Engaging in theft or fraud to support the financial strain of substance use.
Practical Examples
Here are some real-world scenarios and actionable next steps for individuals and families in the Newport Beach area.
-
Scenario 1: Signs of Physical Dependence
- If someone is shaking, sweating, or nauseous after stopping alcohol: They may need medical detox, not just an outpatient program. Withdrawal from alcohol can be dangerous and requires medical supervision.
- Next Step: Search for Newport Beach detox listings that offer 24/7 medical care. Call and ask about their protocol for alcohol withdrawal management.
-
Scenario 2: Loss of Control Without Severe Withdrawal
- If someone can’t stop using despite consequences (job loss, family issues) but is medically stable: Residential or inpatient rehab may be appropriate. This provides a structured, supportive environment away from triggers.
- Next Step: Contact your insurance carrier to ask about coverage for inpatient treatment. Verify your benefits confidentially to understand your options.
-
Scenario 3: Maintaining Daily Responsibilities
- If someone has a job or family obligations and no severe withdrawal symptoms: An Intensive Outpatient Program (IOP) in Newport Beach or Costa Mesa can provide structured care without requiring a full-time stay.
- Next Step: Research local IOP programs and ask about their schedules. Many offer evening or weekend sessions to accommodate work or school.
-
Questions to Ask a Treatment Center During an Intake Call:
- "Do you provide medical detox onsite or refer out?"
- "What does a typical weekly schedule look like for a client?"
- "Is dual diagnosis treatment available for co-occurring mental health conditions?"
- "What insurance plans do you accept, and can you verify my coverage?"
- "What kind of aftercare planning and support is offered?"

2. How are signs of substance use disorder officially diagnosed?
A licensed clinical professional uses the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). A diagnosis is based on a pattern of behaviors related to substance use, occurring over a 12-month period, that fall into four categories: impaired control, social impairment, risky use, and pharmacological criteria (tolerance and withdrawal).
3. Can someone have a substance use disorder without showing all 10 signs?
Yes. An SUD is diagnosed on a spectrum of mild, moderate, or severe, based on how many diagnostic criteria are met. A person may have a mild SUD with only two or three signs present, while someone with a severe disorder will exhibit many more.
