Heroin is a highly addictive drug derived from morphine, which is obtained from the opium poppy. It is a “downer” that affects the brain’s pleasure systems andinterferes with the brain’s ability to recognize pain. Thus, it is used as pain killer or as a recreational drug. Moreover, it has an extremely high potential for abuse.
Depending upon the preference of the user and the drugs’ purity. Heroin can be used in different ways. It can be injected into a vein, injected into a muscle, smoked in a standard pipe, mixed in a marijuana joint, inhaled as smoke through a straw, known as “chasing the dragon,” snorted as powder via the nose.
After a single dose, the short-term effects of abusing heroin appears and in a few hours disappear. After an injection of heroin, the user reports feeling a surge of euphoria accompanied by a warm flushing of the skin, a dry mouth, and heavy extremities. The initial euphoria is followed by an alternation of a wakeful and sleepy state. Mental functioning becomes clouded because of the depression of the central nervous system. Other effects included decreased and slurred speech, slow gait, constricted pupils, droopy eyelids, impaired night vision, vomiting, constipation.
A certain period of time is needed for the appearance of the long-term effects of heroin. Chronic users may develop collapsed veins, infection of the heart lining and valves, abscesses, cellulites, and liver disease. Pulmonary complications, including various types of pneumonia, may result from the poor health condition of the abuser, as well as from heroin’s depressing effects on respiration. In addition to the effects of the drug itself, street heroin may have additives that do not really dissolve and result in clogging the blood vessels that lead to the lungs, liver, kidneys, or brain. This can cause infection or even death of small patches of cells in vital organs. With regular heroin use, tolerance develops. This means the abuser must use more heroin to achieve the same intensity or effect.
Physical dependence and heroin addiction develops as higher doses are used over time. With physical dependence, the body has adapted to the existed of the drug and withdrawal symptoms may occur if use is reduced. Withdrawal, which in regular abusers may happen as early as a few hours after the last administration, produces drug craving, restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps (“cold turkey”), kicking movements (“kicking the habit”), and other symptoms. Major withdrawal symptoms peak between 48 and 72 hours after the last does and subside after about a week. Sudden withdrawal by heavily dependent users who are in poor health can be fatal.
Furthermore, the withdrawal syndrome from heroin may start within 6 to 24 hours of discontinuation of the drug; however, this time frame can change with the degree of tolerance as well as the amount of the last consumed dose. Symptoms may include: sweating, malaise, anxiety, depression, priapism, extra sensitivity of the genitals in females, general feeling of heaviness, cramp-like pains in the limbs, excessive yawning, tears, rhinorrhea, sleep difficulties (insomnia), cold sweats, chills, severe muscle and bone aches; nausea and vomiting, diarrhea, cramps, and fever.
Heroin addiction, just like any other drug addiction starts with occasional use of the drug, which later on would become a habit. This is so because it causes some chemicals in the brain to become dependent to the drug. Moreover, the body itself craves for the drug because of its pleasurable effects. It is relaxing, thus the person feels positively about the drug. And even though it gets to the point that the drug is starting to deteriorate the person, he or she could not get away with it anymore, because he or she has become dependent on heroin. Thus, when the drug intake is suddenly ended, the person experiences withdrawal symptoms. With this, professional help is required for recovery.
