Substance abuse is a complex issue that affects millions of people and their families. It doesn’t discriminate based on age, gender, or socioeconomic status, and its signs can often be subtle, making it difficult for loved ones to recognize. Understanding what to look for is the critical first step toward offering help and encouraging recovery.

If you suspect someone you care about may be struggling with drug or alcohol abuse, here is a guide to recognizing the common physical, behavioral, and psychological indicators.

Physical and Health-Related Changes

The most noticeable signs of substance abuse often manifest in the body and overall health.

Appearance and Grooming

  • Deterioration of hygiene: A noticeable decline in personal grooming habits, such as infrequent showering, unkempt clothing, or poor dental care.
  • Weight fluctuations: Sudden, unexplained weight loss or gain.
  • Changes in skin and eyes: Bloodshot or glazed eyes, dilated or constricted pupils, frequent nosebleeds (for those abusing inhaled drugs), or needle marks/bruises.

Energy and Sleep Patterns

  • Unusual fatigue: Persistent tiredness, lethargy, or excessive sleep, often paired with periods of high energy or insomnia.
  • Changes in appetite: Loss of appetite or unusual food cravings.
  • Slurred speech or impaired coordination: Difficulty speaking clearly, stumbling, or general lack of motor control.

Behavioral and Lifestyle Indicators

Addiction to drugs or alcohol frequently leads to changes in how a person interacts with the world, impacting their responsibilities and relationships.

Responsibility and Performance

AreaSigns to Look For
Work/SchoolFrequent absences, decline in performance, missed deadlines, or sudden lack of interest in activities they once enjoyed.
FinancialUnexplained need for money, borrowing or stealing cash, secretive transactions, or problems paying bills.
LegalRecurring run-ins with the law, such as arrests for intoxication, driving under the influence (DUI), or other drug-related offenses.

Social and Relationship Dynamics

  • Secrecy and isolation: Becoming overly secretive about their whereabouts, locking doors, making private calls, and withdrawing from family and friends.
  • New peer groups: Abruptly switching friends, particularly associating with individuals known to use substances.
  • Unexplained mood swings: Rapid and intense shifts in emotion, often disproportionate to the situation.
  • Lying and defensiveness: Habitually fabricating stories or becoming extremely defensive when questioned about their behavior or activities.

Paraphernalia

  • Finding drug paraphernalia such as pipes, rolling papers, syringes, small plastic bags, or bottles of medication not prescribed to them.
  • Missing prescription medications, either their own or those belonging to others in the household.

Psychological and Emotional Signs

The internal struggle of addiction often surfaces as shifts in personality, attitude, and mental state.

Mood and Temperament

  • Increased anxiety or irritability: Seeming constantly on edge, restless, or easily frustrated.
  • Depression: Persistent sadness, hopelessness, or loss of interest in life.
  • Lack of motivation: Apathetic toward future goals, hobbies, or personal growth.
  • Personality changes: Exhibiting uncharacteristic behaviors, such as increased aggression, paranoia, or reckless decision-making.

Cognitive Function

  • Memory problems: Difficulty recalling events or conversations that took place while under the influence.
  • Difficulty concentrating: Inability to focus on tasks or follow complex instructions.

What Comes Next?

Recognizing these signs is not about diagnosing an addiction, but about acknowledging that a problem exists and that help is needed. If you notice several of these indicators, it’s crucial to approach the situation with compassion, not judgment.

  1. Educate Yourself: Learn about addiction and available resources.
  2. Speak with Care: Choose a private, safe time to express your concerns without accusatory language. Use “I” statements (e.g., “I am worried about you because…”)
  3. Seek Professional Help: Consult with a doctor, therapist, or addiction specialist who can provide a proper assessment and guidance on intervention and treatment options.

Substance abuse is a treatable condition. By recognizing the signs early, you empower yourself and your loved one to take the first courageous steps toward lasting recovery.

Recognizing the Signs of Substance Abuse

Phil Castagnola

Case Manager

Philip was born and raised in San Diego. He grew up with parents who were functioning alcoholics /addicts. This led to adopting a faulty belief system from a very early age that using drugs and alcohol was an acceptable way to live. The belief system made it normal for him to begin using substances at the age of 15.
Philip has been a surfer his entire life and competed professionally for a few years in his 20’s. He has primarily worked in the surf industry. He eventually opened his own surf shop (Select Surf Shop) in the early 2000’s. His addiction eventually got the better of him and after losing his business and his family in 2006 he spent the next 3 years in and out of rehabs trying to recover. His substance abuse issues eventually landed him in federal prison. He used his time wisely and started working the steps of alcoholics anonymous and completing an 18-month treatment program. 
Philip was the primary caregiver for his mom who was permanently bedridden for the last 4 years. When covid hit he decided to pursue one of his goals and began going to school to become a substance abuse counselor.

After struggling with substance abuse issues for over 20 years philip now has 1 years of continuous sobriety and works a program of recovery givi4ng back to other addicts and alcoholics through sponsorship in the program of AA.

Philip studied AODS at San Diego City College and he is now completing his internship here at Coastal Detox of Southern California.

Philip’s main passion is sharing his experience, strength and hope with others who struggle with substance abuse issues. Helping others through their journey of getting and remaining free of their bondage of addiction.

Jeff Swem, SUDRC

Director of Operations

Jeff was born and raised in San Diego, and spent much of his youth living blocks from where our residential housing is located.  He spent his teenage years skateboarding up and down the surrounding streets, and enjoying the Pacific Beach life in the 80’s/early 90’s. 

Jeff got to know the darker side of addiction early in life, with three near-death experiences in a row happening within a year.  He “settled down” into alcohol, and later in life became a professional brewer, but that too proved to be too cunning, baffling, and powerful a draw.  During Covid, he felt no choice but to surrender, and made the decision to get sober.  He attended a similar program to our own, and after completing the 30 days inpatient and attending IOP aftercare, he was able to forge a strong foundation of sobriety.  He has not found a reason to pick up a drink since the day that he checked into that detox.  After quitting the brewing gig (because of course, he had little choice there), he enrolled in the AODS program at City College with his sights on a new career of helping others.  Having completed the requirements involved, he went on to earn his certification in California for Substance Use Disorder Certified Counselor.

Jeff is married to his wife of nearly 25 years with a 21 year old daughter and 18 year old son, and thanks to the 12 steps, surrounding himself with a caring and supportive sober community, and coming to terms with his alcoholism, is able to lead others struggling with addiction through example and personal experience.
