Heroin Abuse Causes, Addiction Signs, Symptoms & Side Effects

Heroin is a fast-acting, highly addictive drug that is processed from morphine, a legal opioid narcotic. Unlike morphine, heroin is an illegal substance and the most commonly abused drug of the opioid class. Usage of heroin creates a state of relaxation and euphoria for the user that’s caused by the binding of the drug to the body’s endorphin sites. By binding to the body’s natural pain relievers, heroin blocks signals to the brain which in turn blocks an individual’s ability to feel pain.

Most commonly, heroin is used intravenously by injection with a needle. Other forms of use include smoking, inhalation with a pipe, snorting, or inhalation with the use of a straw.

Immediately after heroin is injected, it crosses the blood-brain barrier, where it is converted into morphine and binds to opioid receptors. Once consumed heroin is said to create a surge of pleasurable sensations, which is referred to as a “rush” or “high.” The intensity of the rush depends on how much of the drug is taken and how fast it enters the brain. The immediacy with which heroin enters the brain and the resulting “rush” is what makes this drug so addictive.

Heroin is most commonly found in white or brown powder form. Other forms of heroin may include a black sticky substance known as “black tar heroin.” Acquiring heroin on the streets is dangerous because you cannot be sure what it is mixed with or the exact level of purity you are receiving. Often street heroin is mixed with sugar, starch, pesticides, or other poisons which puts heroin users at an increased level of risk for overdose and death. Other common street names for heroin include: “smack,” “thunder,” “poppy,” “white junk,” and “dead on arrival.”

Statistics on Heroin Abuse

It’s estimated that 9.2 million people use heroin worldwide. In 2011, 1.6%, or 4.2 million Americans over the age of twelve had used heroin at least once in their lives. Approximately 23% of people who use heroin later become dependent upon it.

Co-Occurring Disorders

Many times individuals who abuse heroin have other co-occurring disorders. Sometimes the presence of this other unaddressed disorder contributes to the heroin abuse and addiction. These co-occurring disorders can often make the treatment and recovery process for heroin abusers more complicated.

Some disorders that may be present with heroin abuse and addiction include:

  • Depression
  • Alcohol abuse
  • Conduct disorder
  • Bipolar disorder
  • Antisocial personality disorder
  • Post-traumatic stress disorder
  • Anxiety disorders
  • Schizophrenia

Causes of Heroin Abuse

No specific cause to heroin has been identified, but research supports a number of possibilities. These possibilities include:

  • Genetic: Research has suggested genetics as a cause for heroin addiction. Individuals who have family members that are addicted to heroin or other substances appear to be more likely to develop a heroin addiction than those without a family history of the disorder.
  • Biological: Another theory suggests the possibility that some individuals may not produce enough natural endorphins in their brain which has an effect on mood. This could lead to heroin abuse in order to cope with this chemical imbalance.
  • Environmental: It has been postulated that people who have been exposed to a parent or guardian abusing heroin or other drugs may be at a greater risk for developing substance abuse problems in later life. Seeing the drug abused can cause a child to “normalize” the drug, therefore making it more accessible later in life.

  • Involuntary commitment to mental hospital
  • Dependence on heroin
  • Suicide
  • Death from overdose or disease

Effects of Withdrawal

After an individual has become physically and psychologically dependent on heroin, once they stop using they begin to go through withdrawal. For individuals who are dependent on heroin, withdrawal symptoms can occur in as little as six to twelve hours after the last dose. They are usually at their most intense within one to three days and then gradually subside over a five to seven day period. However, the more chronic symptoms like anxiety, insomnia, and drug craving last for months. Due to the extreme discomfort of withdrawal symptoms, individuals often relapse.

The negative effects of withdrawal cause significant distress or impairment in an individual’s daily life. Some symptoms include:

  • Anxiety
  • Muscle aches
  • Increased sweating
  • Nausea or vomiting
  • Restlessness
