Heroin

Heroin

Heroin

is an opioid drug that is synthesized from morphine, a naturally occurring substance extracted from the seed pod of the Asian opium poppy plant. Heroin usually appears as a white or brown powder or as a black sticky substance, known as “black tar heroin.”

Prescription Opioid Abuse: A First Step to Heroin Use?

Heroin Brochure

Prescription opioid pain medications such as Oxycontin and Vicodin can have effects similar to heroin when taken in doses or in ways other than prescribed, and they are currently among the most commonly abused drugs in the United States. Research now suggests that abuse of these drugs may open the door to heroin abuse.

Nearly half of young people who inject heroin surveyed in three recent studies reported abusing prescription opioids before starting to use heroin. Some individuals reported taking up heroin because it is cheaper and easier to obtain than prescription opioids.

Many of these young people also report that crushing prescription opioid pills to snort or inject the powder provided their initiation into these methods of drug administration.

 

How Is Heroin Used?

Heroin can be injected, inhaled by snorting or sniffing, or smoked. All three routes of administration deliver the drug to the brain very rapidly, which contributes to its health risks and to its high risk for addiction, which is a chronic relapsing disease caused by changes in the brain and characterized by uncontrollable drug-seeking no matter the consequences.

How Does Heroin Affect the Brain?

When it enters the brain, heroin is converted back into morphine, which binds to molecules on cells known as opioid receptors. These receptors are located in many areas of the brain (and in the body), especially those involved in the perception of pain and in reward. Opioid receptors are also located in the brain stem, which controls automatic processes critical for life, such as blood pressure, arousal, and respiration.

Heroin overdoses frequently involve a suppression of breathing. This can affect the amount of oxygen that reaches the brain, a condition called hypoxia. Hypoxia can have short- and long-term psychological and neurological effects, including coma and permanent brain damage.

After an intravenous injection of heroin, users report feeling a surge of euphoria (“rush”) accompanied by dry mouth, a warm flushing of the skin, heaviness of the extremities, and clouded mental functioning. Following this initial euphoria, the user goes “on the nod,” an alternately wakeful and drowsy state. Users who do not inject the drug may not experience the initial rush, but other effects are the same.

Researchers are also investigating the long-term effects of opioid addiction on the brain. One result is tolerance, in which more of the drug is needed to achieve the same intensity of effect. Another result is dependence, characterized by the need to continue use of the drug to avoid withdrawal symptoms. Studies have shown some deterioration of the brain’s white matter due to heroin use, which may affect decision-making abilities, the ability to regulate behavior, and responses to stressful situations.

Injection Drug Use and HIV and HCV Infection

People who inject drugs are at high risk of contracting HIV and hepatitis C (HCV). This is because these diseases are transmitted through contact with blood or other bodily fluids, which can occur when sharing needles or other injection drug use equipment. (HCV is the most common blood-borne infection in the Unites States.) HIV (and less often HCV) can also be contracted during unprotected sex, which drug use makes more likely.

Because of the strong link between drug abuse and the spread of infectious disease, drug abuse treatment can be an effective way to prevent the latter. People in drug abuse treatment, which often includes risk reduction counseling, stop or reduce their drug use and related risk behaviors, including risky injection practices and unsafe sex.

 

 

How is heroin harmful?
  • Heroin is an illegal, highly addictive opioid drug.
  • A heroin overdose can cause slow and shallow breathing, coma, and death.
  • People often use heroin along with other drugs or alcohol. This practice is especially dangerous because it increases the risk of overdose.
  • Heroin is typically injected but is also smoked or snorted. When people inject heroin, they are at risk of serious, long-term viral infections such as HIV, Hepatitis C, and Hepatitis B, as well as bacterial infections of the skin, bloodstream, and heart.
Who is most at risk of heroin addiction?
  • People who are addicted to prescription opioid painkillers
  • People who are addicted to cocaine
  • People without insurance or enrolled in Medicaid
  • Non-Hispanic whites
  • Males
  • People who are addicted to marijuana and alcohol
  • People living in a large metropolitan area
  • 18 to 25 year olds

What Are the Other Health Effects of Heroin?

Opioid abuse is associated with a number of serious health conditions, including fatal overdose, spontaneous abortion, and infectious diseases like hepatitis and HIV (see box, “Injection Drug Use and HIV and HCV Infection”). Chronic users may develop collapsed veins, infection of the heart lining and valves, abscesses, constipation and gastrointestinal cramping, and liver or kidney disease. Pulmonary complications, including various types of pneumonia, may result from the poor health of the user as well as from heroin’s effects on breathing.

In addition to the effects of the drug itself, street-heroin often contains toxic contaminants or additives that can clog blood vessels leading to the lungs, liver, kidneys, or brain, causing permanent damage to vital organs.

Chronic use of heroin leads to physical dependence, a state in which the body has adapted to the presence of the drug. If a dependent user reduces or stops use of the drug abruptly, he or she may experience severe symptoms of withdrawal. These symptoms—which can begin as early as a few hours after the last drug administration—can include restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps (“cold turkey”), and kicking movements (“kicking the habit”). Users also experience severe craving for the drug during withdrawal, which can precipitate continued abuse and/or relapse.

Besides the risk of spontaneous abortion, heroin abuse during pregnancy (together with related factors like poor nutrition and inadequate prenatal care) is also associated with low birth weight, an important risk factor for later delays in development. Additionally, if the mother is regularly abusing the drug, the infant may be born physically dependent on heroin and could suffer from neonatal abstinence syndrome (NAS), a drug withdrawal syndrome in infants that requires hospitalization. According to a recent study, treating opioid-addicted pregnant mothers with buprenorphine (a medication for opioid dependence) can reduce NAS symptoms in babies and shorten their hospital stays.

    A California Assemblywoman wants to open public health clinics throughout the state in which heroin addicts and other drug users could legally go to get their high under supervised care.

    The bill, AB-2495 , sponsored by Assemblywoman Susan Talamantes Eggman, D-Stockton, would create first-in-nation legal drug supervised injection sites (SIS). The bill faces a contentious battle.

    On one side, proponents say opening local and state health department facilities to monitor and treat overdoses would save money and lives.
