Effects of Opiates
Psychological
Effects of Opiates
Like other depressants, opiates produce a tranquil and euphoric effect. Users
who inject an opiate such as heroin may also experience a "rush" as
the drug circulates through the body. Some users combine opiates with a stimulant
such as cocaine. This is called "speed balling." The stimulant keeps
the user from falling asleep; the opiate reduces the hyperactive effects often
caused by stimulants.
Psychological dependence is probable with continued use of opiates. When a user
becomes dependent, finding and using the drug becomes the main focus of life.
Opiates induce tolerance: the need for more of the drug in order to produce the
same effects.
Physical
Effects of Opiate Use
The physical effects of opiates depend on the opiate used, its source, the dose
and the method used. Opiates slow breathing, heart rate and brain activity. Opiates
depress appetite, thirst and sexual desire. The body's tolerance to pain is increased.
Potential contamination, using opiates in combination with other drugs, and using
un-sterile needles all increase the danger of opiates. Use of UN-sterile needles
can lead to hepatitis, tetanus or AIDS.

Regular opiate users who abruptly stop using the drug experience withdrawal symptoms
four to six hours following the last dose. Symptoms include uneasiness, diarrhea,
abdominal cramps, chills, sweating, nausea, runny nose and eyes, irritability,
weakness, tremors and insomnia. The intensity of these symptoms depends on how
much of the drug was taken, how often and for how long. These symptoms are usually
strongest 24 to 72 hours after onset and can persist for seven to 10 days.
Sometimes sleeplessness and craving for the drug can last for several
months.

Opiates are harmful to a developing fetus. Pregnant women who are dependent on
opiates have a higher risk for spontaneous abortions, breech deliveries, premature
births and stillbirths. Babies born to opiate-addicted mothers often have withdrawal
symptoms similar to adults. These symptoms may last several weeks or months. Researchers
have also found an increased risk of Sudden Infant Death Syndrome (SIDS) among
babies born to heroin-addicted mothers.
