Everyone’s experience with alcohol or drug use is different, but there are some common signs that substance use may be starting to affect health, mood, or daily life.
Physical changes may include red or glassy eyes, sudden weight loss or gain, changes in sleep or appetite, poor hygiene, or shaking and dizziness. People may notice blackouts, memory gaps, or withdrawal symptoms such as sweating, shakiness, or nausea. Over time, health issues like liver, stomach, or heart problems can also appear.
Behavioural changes can include secrecy, mood swings, irritability, or acting in risky ways. There may be strong cravings, using more than intended, or repeated struggles to cut down or stop. A lot of time may be spent using, recovering, or thinking about substances, often leading to falling behind at work, school, or home responsibilities.
Impact on life often shows up as withdrawing from friends or family, losing interest in hobbies, or having ongoing money problems. Conflicts in relationships may increase, trust can break down, and legal or job issues may appear. Some people continue to use despite health or relationship problems, and mental health concerns such as anxiety, low mood, or thoughts of self-harm can also develop.
