White Powder Street Heroin
Moreover, The purest form of drug is white powder heroin, known as diacetylmorphine hydrochloride, although it will typically be mixed or “cut” with other white powders, which reduce the potency and increase the risk of contamination and vein damage if the drug is injected.
In its purest form, heroin is a fine white powder. But more often, it is found to be rose gray, brown or black in color. The coloring comes from additives which have been used to dilute it, which can include sugar, caffeine or other substances. Street heroin is sometimes “cut” with strychnine1 or other poisons.
The various additives do not fully dissolve, and when they are injected into the body, can clog the blood vessels that lead to the lungs, kidneys or brain. This itself can lead to infection or destruction of vital organs.
Pure heroin is a white powder with a bitter taste that predominantly originates in South America and, to a lesser extent, from Southeast Asia, and dominates U.S. markets east of the Mississippi River.3 Highly pure heroin can be snorted or smoked and may be more appealing to new users because it eliminates the stigma associated with injection drug use.
“Black tar” heroin is sticky like roofing tar or hard like coal and is predominantly produced in Mexico and sold in U.S. areas west of the Mississippi River.3
The dark color associated with black tar heroin results from crude processing methods that leave behind impurities. Impure heroin is usually dissolved, diluted, and injected into veins, muscles, or under the skin.Black tar heroin often looks like sticky tar, or can sometimes look like a hard piece of coal.
In some cases, black tar heroin may also look dark orange or dark brown. The color and consistency of black tar heroin are due to the low-quality processing methods that leave impurities behind.
