The most dangerous and addictive narcotic is heroin. While receiving less publicity today than newer, more popular drugs, it continues to be a major problem in this country. Not only is heroin extremely addictive and dangerous, but as with cocaine and methamphetamines, addicts often resort to crimes such as burglary, grand theft, robbery, or prostitution to support their habits.

Sometimes called black tar, mud, smack, China white, or Mexican brown, heroin is derived from opium poppies. In its powder form, it may range in color from white to a very dark brown. The most popular form of heroin is a dark tar-like substance called black tar, which is sold in small foil or cellophane packets or in small toy balloons.

The most common use of heroin is by injection (called "mainlining" or "shooting"), but in it's powder form it can be inhaled through the nose or smoked. Paraphernalia for injecting heroin include hypodermic needles, small cotton balls used to strain the drug, and water and spoons or bottle caps used for "cooking" or liquefying the heroin. Paraphernalia for inhaling or smoking heroin includes razor blades, straws, rolled dollar bills, and pipes. The high from the drug usually lasts from four to six hours.

If your child is under the influence of heroin, he or she may have constricted pupils, droopy eyelids, depression, apathy, decreased physical activity, and nausea. A frequent user may nod or appear sleepy, and repeatedly scratch or touch their face and nose. Larger doses of heroin may induce sleep, vomiting, and shallow breathing. An overdose can cause slow and shallow breathing, clammy skin, convulsions, coma, or death.

In addition, there is a family of chemically manufactured drugs often referred to as "designer drugs". These drugs have been falsely represented as "synthetic heroin." The most prevalent of these "designer drugs" is fentanyl citrate, also called China white, which is many times more powerful than heroin and has caused a number of deaths among addicts. Fentanyl citrate is used in the same manner as heroin.
