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 heroin 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 heroin use.
Physical Symptoms of Heroin Use
Heroin is a type of opioid, but unlike some opioids (like oxycodone and morphine), heroin has no accepted medical use. It is a Schedule I drug and has a high risk of abuse. Heroin use may result in the following physical changes and symptoms:
- Constricted Pupils: Heroin’s stimulating effects cause the pupils to constrict called “pinpoint pupils.”
- Flu-Like Symptoms from Withdrawal: A user may experience flu-like symptoms such as a runny nose, muscle aches, and excessive sweating.
- Liver Damage: Continual use of heroin will damage the liver and cause it to not function properly. This can lead to other health consequences from poor liver function or failure.
- Weight Loss: Heroin users often experience sudden and significant weight loss.
- Severe Constipation
- Puncture Wounds: Heroin users may have puncture wounds on their arms in the form of bruises, infections, scabs, or vein damage.
Behavioral Symptoms of Heroin Use
The physical symptoms of heroin 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 heroin use include:
- Anxiety and Paranoia: Irrational suspicions, anxiety, delusional thoughts, outbursts, or self-consciousness are all symptoms of heroin use.
- Social Withdrawal: Heroin users may withdraw from social crowds, family, activities, or hobbies that they used to enjoy.
- Shirking Responsibilities: Heroin users may avoid responsibilities such as work, school, or family obligations. Their performance may decline as heroin users have difficulty making decisions and concentrating on tasks.
- Mood Swings: Sudden mood swings from extreme irritability to euphoria and carelessness can be a sign of heroin use.
