1. Drowsiness

Constant drowsiness is a common side effect of narcotics abuse. Because opioids tend to make an individual drowsy and abusers may take these drugs once a day or more, the person may feel sleepy much of the time and unable to take on their responsibilities, even becoming apathetic toward daily activities.

2. Cravings

Someone who becomes physically or even psychologically dependent on opioids could take them as prescribed and become dependent on the drug. Dependence is not the same as abuse and can still cause withdrawal symptoms. Someone who experiences cravings, however, when they stop taking narcotics, is abusing the drug and may be addicted.

3. Respiratory Depression

Any time someone abuses high doses of opioids, they have the potential of experiencing “severe respiratory depression” and overdose that can lead to coma and death (NIDA). Even if the individual does not realize how dangerous this is, it can be noticeable and lead to slow and shallow breathing or no breathing at all leading to death. This type of overdose is the result of narcotic abuse.

4. Euphoria

Someone who displays the euphoria common with opioid use should be watched closely. These drugs can cause this effect but usually only when it’s being taken at levels high enough to constitute abuse (prescribed dosages do not usually cause euphoria). You may need to seek treatment for someone who constantly experiences a euphoric high from narcotics because they are likely abusing their medication to feel this way.

5. Secretive or Dangerous Behavior

Someone who abuses narcotic drugs may engage in secretive or dangerous behavior to obtain more or hide their abuse. They may:

• Steal or forge prescriptions to get more of the drug
• Steal drugs from a doctor’s office or hospital
• Hide drugs in places they don’t believe you will find them
• Become paranoid or hostile when you bring up their drug abuse

6. Constipation

Constipation is the most common complaint of individuals taking narcotics by prescription since the drug slows your digestive system. If you abuse the drug, there is an even higher chance that you could experience this issue. Someone who is constipated as a result of narcotics abuse may visit their doctor, take over-the-counter medication or do anything to solve it that does not involve stopping their abuse of the drug.

7. Constant Nausea

Nausea is a common side effect of prescription opioids and their abuse can often cause a more intense or at least a more consistent nauseous reaction. Someone who abuses heroin or other illicit narcotics will also experience this issue. It can also cause a lack of appetite at times.

8. Crushing Pills

Prescription opioids are not meant to be taken this way, which can be very dangerous and bring on respiratory depression more intensely if the drug is snorted or injected. This behavior is common among narcotics abusers and it is unsafe. If you notice anyone taking a prescription opioid pill this way, this is a common and clear sign of abuse.

9. Making Excuses

The NLM lists one of the symptoms of drug abuse as “making excuses to use drugs.” If someone is constantly coming up with reasons to take narcotics (they just need them to fall asleep, they are used to taking them, etc.) this could be a strong warning sign of abuse.

10. Seizures

Seizures are an intense and sometimes dangerous side effect of some prescription opioids like oxycodone. Someone who suddenly experiences seizures who has never had an issue with them in the past could be having them as a serious side effect of narcotics abuse. Seizure activity is not normal and can trigger neurological damage if not treated promptly and appropriately.

11. Work or School Problems

Because people using narcotics can become apathetic, they might not attend work or school as frequently as before and definitely will not take it as seriously. This kind of issue can be a cause for alarm, especially if it comes on very suddenly. The person may

• Have a severe dip in their grades
• Not perform as well at work or school
• Be reprimanded by a teacher or employer
• Get fired or expelled for using drugs during work/school hours
• This is a definite warning sign of abuse that is skirting the territory of addiction.

12. Mixing with Alcohol

People who abuse narcotics often mix these drugs with alcohol, a common practice that is especially dangerous. According to the NIDA, “These medications are not safe to use with alcohol… because their combined effects also cause serious breathing problems that could lead to death.” Someone who uses drugs and alcohol consistently while knowing the dangers is likely abusing the drug often and in more dangerous ways.

13. Dry Mouth

Individuals who abuse narcotics can also experience dry mouth, a common symptom caused by the drug. The individual might try to hide it or get rid of it by constantly drinking water or other liquids, but a dry mouth becomes more noticeable as a person continues to abuse narcotics.

14. Sudden Mood Changes

When someone abuses narcotics, their mood often fluctuates between euphoria and depression or irritability after crashing. These sudden and intense mood changes will be noticeable and will not stop immediately when the person is not on the drug. The individual might exhibit signs of:

• Apathy
• Depression
• Euphoria
• Fatigue
• Irritability
• Calmness
• Confusion

15. Using the Drug for Wrong Reasons

Any time someone uses narcotics for any reason other than to treat pain as part of a doctor’s prescribed treatment regimen, it is a form of abuse that could become worse over time. Someone who says one of the phrases below is showing a warning sign of narcotic abuse:

• “It makes me feel good.”
• “It helps me sleep.” (without the presence of pain)
• “It makes it easier to deal with my daily life.”
• “It makes me calmer.”
• “I do it so I can have more fun at a party.”
• “I feel more normal when I take it.”
