Warning Signs of Substance Use in Your Home
When someone you love begins acting differently, it can be difficult to know what is happening.
Maybe your teenager has become unusually withdrawn. Perhaps your partner's mood has changed, money is disappearing, or someone who was once reliable is suddenly missing work, school, or family responsibilities.
Your first thought may be: Could drugs or alcohol be involved?
That possibility can bring fear, anger, confusion, and even guilt. But recognizing potential warning signs early can help you respond thoughtfully and connect your loved one with appropriate support.
At Mar Y Sol Mental Health Experts, we encourage families to look for patterns of change rather than one isolated behavior. No single sign proves that someone has a substance use disorder, and many of these symptoms can occur with depression, anxiety, trauma, medical conditions, or other mental health concerns.
The important thing is to pay attention when several changes begin happening together.
Changes in Behavior
One of the first things families often notice is that the person simply doesn't seem like themselves.
You may notice changes such as:
Becoming increasingly withdrawn from family
Spending significantly more time alone
Increased secrecy about activities or whereabouts
Sudden irritability, anger, or mood changes
Losing interest in hobbies or activities they previously enjoyed
Changing friend groups unexpectedly
Frequently asking for money without a clear explanation
Becoming defensive when asked simple questions
Breaking household rules or responsibilities that were previously important to them
Changes in motivation or reliability
Again, these behaviors do not automatically mean someone is using drugs or alcohol.
But when several changes appear together—particularly when they represent a significant difference from the person's usual behavior—it may be worth exploring what is happening.
Physical Signs That May Be Associated With Substance Use
Different substances affect the body in different ways, so there is no single physical appearance that identifies substance use.
Possible changes may include:
Significant changes in sleep patterns
Sleeping much more or much less than usual
Unexplained weight loss or weight gain
Bloodshot or unusually glassy eyes
Changes in pupil size
Slurred speech
Unusual coordination or balance problems
Tremors or shaking
Excessive sweating
Frequent nosebleeds or runny nose
Changes in appetite
Decline in grooming or personal hygiene
Unexplained fatigue or periods of unusually high energy
Sudden or severe physical changes deserve medical attention regardless of whether substance use is the cause.
Some withdrawal syndromes—particularly withdrawal from alcohol or certain sedative medications—can become medically dangerous and should not be managed at home without professional guidance.
Changes Around the Home
Sometimes families first become concerned because they notice unfamiliar objects, missing medications, or unusual changes around the house.
Possible warning signs can include:
Prescription medications disappearing faster than expected
Missing alcohol
Unexplained missing cash or valuables
Empty alcohol containers hidden in unusual places
Small plastic bags or unusual containers
Pipes, syringes, burnt foil, or other unfamiliar drug-related items
Frequent use of eye drops, breath products, or fragrances to conceal physical signs or odors
Unusual chemical, smoky, or sweet odors
Packages or deliveries that are difficult to explain
Finding an unfamiliar object can be alarming, but avoid jumping immediately to conclusions.
If possible, approach the situation with the goal of understanding what is happening rather than immediately accusing or confronting the person.
Problems at School or Work
Substance use can interfere with concentration, motivation, attendance, judgment, and performance.
You may notice:
A sudden decline in grades
Missing classes
Frequent absences from work
Repeated lateness
Difficulty completing assignments or responsibilities
Disciplinary problems
Conflicts with teachers, supervisors, or coworkers
Losing a job
Frequently changing jobs
Giving up activities, educational goals, or career plans that were previously important
A significant decline in functioning is important even when substance use is not the cause.
Depression, anxiety, ADHD, trauma, bullying, sleep disorders, and other conditions can produce similar changes. A comprehensive evaluation can help determine what may be contributing.
Changes in Relationships
Substance use disorders often affect more than the individual.
Families may notice increasing:
Arguments
Broken promises
Isolation
Secrecy
Financial problems
Loss of trust
Unpredictable behavior
Disappearing for extended periods
Conflict about drinking or drug use
You may find yourself constantly checking on the person, making excuses for them, lending money, covering missed responsibilities, or trying to prevent the next crisis.
Over time, the entire household can begin revolving around one person's substance use.
That is one reason support for family members can also be an important part of recovery.
Mental Health Changes Matter Too
Substance use and mental health conditions frequently overlap.
A person struggling with alcohol or drugs may also be experiencing:
Depression
Anxiety
Trauma
ADHD
Mood instability
Insomnia
Suicidal thoughts
Chronic stress
Sometimes substances are being used as a way to cope with emotional pain, anxiety, trauma, loneliness, or difficulty sleeping.
Other times, substance use itself contributes to worsening mood, anxiety, paranoia, irritability, or other psychiatric symptoms.
At Mar Y Sol Mental Health Experts, we believe it is important to evaluate both.
Treating substance use without addressing mental health can leave an important part of the problem untreated.
How Should You Talk to Someone You Are Worried About?
The way you begin the conversation matters.
Try to choose a time when the person is not intoxicated and when emotions are relatively calm.
Focus on specific things you have observed rather than accusations.
For example, instead of saying:
“I know you're using drugs.”
You might say:
“I've noticed that you haven't been sleeping, you've missed work several times, and you haven't seemed like yourself lately. I'm concerned about you. What's going on?”
Listen before immediately trying to solve the problem.
Your goal is not to win an argument. Your goal is to open a conversation.
You can express concern while still maintaining appropriate boundaries.
Supporting someone does not require ignoring unsafe behavior, giving unlimited money, covering up consequences, or placing yourself or other family members at risk.
When Is Substance Use an Emergency?
Some situations require immediate medical attention rather than waiting for an outpatient appointment.
Call 911 if someone:
Is unconscious or cannot be awakened
Is breathing very slowly, irregularly, or not breathing
Has blue or gray lips or fingertips
Is having a seizure
Is severely confused or hallucinating
Has taken an unknown substance and is becoming medically unstable
Is threatening suicide or has made a suicide attempt
If opioid overdose is suspected and naloxone (Narcan) is available, administer it according to its instructions and call 911.
Someone who wakes up after naloxone still needs emergency medical evaluation because naloxone can wear off while the opioid remains in the body.

Early Help Can Make a Difference
You do not need to wait until someone has lost their job, damaged important relationships, been arrested, overdosed, or reached what people sometimes call “rock bottom” before seeking help.
There is no medical requirement to hit rock bottom.
If something has changed and you are concerned, that concern is enough reason to start a conversation or request an evaluation.
At Mar Y Sol Mental Health Experts, we understand that taking the first step can be difficult for both patients and families.
We provide care with compassion, respect, and without judgment.
If you are concerned about substance use in yourself, your teenager, your partner, or another family member, contact Mar Y Sol Mental Health Experts at (203) 456-6989 to learn more about our treatment options.
Recognizing a problem is not the end of someone's story. It can be the beginning of recovery.

Frequently Asked Questions
What are some of the earliest signs of substance use?
Early signs vary considerably. Families may notice changes in mood, sleep, friendships, responsibilities, money, school or work performance, secrecy, or interest in usual activities. One change alone does not prove substance use. A pattern of significant behavioral and functional changes deserves attention.
Does a sudden drop in grades or work performance mean someone is using drugs?
Not necessarily. Substance use is one possible explanation, but depression, anxiety, ADHD, trauma, sleep problems, bullying, family stress, and medical conditions can also affect performance. The cause should be evaluated rather than assumed.
What physical changes can happen with substance use?
Depending on the substance, changes can include unusual sleep patterns, weight or appetite changes, bloodshot eyes, changes in pupils, tremors, sweating, impaired coordination, slurred speech, fatigue, or changes in personal hygiene. Symptoms vary considerably depending on the substance and individual.
Should I confront someone if I think they are using drugs?
A calm conversation is generally more productive than an angry confrontation. Talk about the specific changes you have observed, express your concern, and give the person an opportunity to respond. If there is violence, suicidal behavior, overdose risk, severe intoxication, or another immediate safety concern, seek emergency assistance instead.
Can someone have both a mental health condition and a substance use disorder?
Yes. Mental health conditions and substance use disorders frequently occur together. Effective treatment should consider both rather than automatically assuming that every symptom is caused by substance use.
Do we have to wait until someone “hits rock bottom” before getting treatment?
No. Earlier intervention can help prevent additional medical, emotional, family, legal, occupational, or educational consequences. A person does not have to lose everything before being deserving of—or benefiting from—treatment.
