Long-term heroin use can have devastating effects on both physical and mental health. The chronic use of heroin can lead to a wide range of health problems, including:
Severe constipation: Heroin use can slow down bowel function, leading to severe constipation and gastrointestinal issues. Chronic constipation can cause discomfort, pain, and, in severe cases, bowel obstruction.

Dental problems: Heroin use can cause significant dental issues, including tooth decay, gum disease, and tooth loss. This is often referred to as “meth mouth,” characterized by extensive tooth decay, gum disease, and tooth loss, which can have a severe impact on a person’s overall health and quality of life.

Loss of appetite: Chronic heroin use can lead to a loss of appetite and significant weight loss. Poor nutrition and weight loss can weaken the immune system, making individuals more susceptible to infections and other health problems.

Menstrual and fertility problems (in females): Heroin use can disrupt menstrual cycles and lead to fertility issues in women. Irregular or absent menstrual cycles can make it difficult for women to conceive and carry a pregnancy to term.

Loss of sex drive (in men): Heroin use can decrease testosterone levels in men, leading to a loss of sex drive and potential erectile dysfunction. Chronic heroin use can also affect reproductive function and fertility in men.

Mood swings, depression, anxiety, and confusion: Long-term heroin use can lead to significant changes in mood, including mood swings, depression, anxiety, and confusion. These mental health issues can have a profound impact on a person’s quality of life and ability to function in daily life.

Skin and lung infections: Heroin users are at an increased risk of developing skin and lung infections, particularly if they inject the drug. Skin infections can occur at the injection site and may lead to abscesses, cellulitis, and other serious complications. Lung infections, such as pneumonia and tuberculosis, are also common among heroin users.

Heart infections (endocarditis), leading to damaged heart valves: Heroin use can increase the risk of developing endocarditis, a serious infection of the heart valves that can lead to permanent damage. Endocarditis is a life-threatening condition that requires prompt medical treatment.

Severe blood infections: Heroin users are at an increased risk of developing severe blood infections, which can be life-threatening. Injection drug use, needle sharing, and poor injection practices can introduce bacteria and other pathogens into the bloodstream, leading to serious infections such as sepsis and bacteremia.

Damaged veins from injecting behavior: Injecting heroin can lead to damaged veins, scarring, and the development of abscesses. Chronic venous damage can make it difficult for individuals to inject heroin and may lead to other complications, such as deep vein thrombosis and pulmonary embolism.

Blood-borne infections such as hepatitis B, hepatitis C, and HIV: Heroin users are at an increased risk of contracting blood-borne infections due to needle sharing and risky injection behaviors. Hepatitis B, hepatitis C, and HIV are serious viral infections that can have long-term health consequences if left untreated.
