Signs and Symptoms of Opioid Use
Individuals using drugs are usually skilled at covering up their drug dependence. They may deny drug use and cover their tracks carefully at first. But eventually, loved ones, co-workers, and employers may start to notice unusual behaviors that make them suspect drug use and dependence.
Knowing the signs and symptoms of opioid use is vital for the health and safety of drug-dependent individuals and those around them. Getting drug-dependent individuals the help they need to break their addictions will restore their physical, mental, and emotional health. Here are common signs of opioid use.
Physical Symptoms of Opioid Use
Opioid dependence may result in the following physical changes and symptoms:
- Constricted Pupils: Constricted, or pinpoint, pupils are a common symptom of opioid use due to the drug’s effects. The eyes may or may not be bloodshot.
- Sleepiness or Drowsiness: Someone who is drifting in and out of sleep, or appears drowsy or lethargic, may be overusing opioids.
- Slurred or Slow Speech: Opioids can cause slurred or slow speech. Slurred speech may be present with or without overall drowsiness.
- Poor Coordination and Motor Control: Motor skills and coordination can be affected by opioid use. Unsteady walking, clumsiness, or poorly coordinated movements are signs of opioid use.
- Puncture Marks: Another way to consume opioids is intravenously. This would result in puncture marks, most commonly on the arms, and there may be bruising or infections at the puncture sites.
- Blisters or Black Fingers: Another way to take opioids is through smoking. There may be blisters around the mouth and nostrils or black fingers.
- Nostril Disorders: A user can consume opioids by snorting the substance, which can result in frequent runny or bloody noses or powder around the nostrils.
- Digestive Issues: The final way to consume opioids is through ingestion. There may be fewer outward physical signs, but ingestion causes weight loss and constipation.
Behavioral Symptoms of Opioid Use
The physical symptoms of opioid use may be easy to cover up with clothing or proper hygiene, but sudden or troublesome behavioral symptoms may be more difficult to conceal. Behavioral symptoms of opioid use include:
- Risky Behaviors: Opioids can make users feel invincible and, therefore, exhibit riskier behavior. These behaviors may be violent, sexual, or dangerous. Opioid users may also be more impulsive decision makers.
- Declining Performance or Interests: Opioid users will noticeably decline in their academic or work performance. They will also not find previous hobbies or friends interesting.
- Mood Swings: Sudden mood swings from extreme irritability to euphoria and carelessness can be a sign of opioid use.
- Doctor Shopping: Opioid users may spend excessive time pursuing new doctors who will fulfill their previous opioid prescriptions.
