Heroin (INN: diacetylmorphine, BAN: diamorphine) is a semi-synthetic opioid synthesized from morphine, a derivative of the opium poppy. The white crystalline form is commonly the hydrochloride salt diacetylmorphine hydrochloride. Upon crossing the blood-brain barrier, which occurs soon after introduction of the drug into the bloodstream, heroin is converted into monoacetylmorphine and morphine, the compounds that mimic the action of endorphins, creating a sense of extreme well-being with the feeling centered in the gut. Heroin affects the bodies Central Nervous System over stimulating the bodies creation of its own naturally occurring pain killers known as endorphins. Long term use can lead to intense physical dependence known as being SICK. Symptoms such as uncontrollable bowel functions, vomiting, sweating, and intense muscle aches, especially in the lower legs are common, and last acutely anywhere from 7 to 10 days. Acute withdrawal is followed by a feeling of lag where even the most common functions like brushing ones teeth is a chore. This lag can last months. A first time user takes longer to acquire a habit (addicted), than someone who has already been addicted. One of the most common methods of heroin use is via intravenous injection, although it may be smoked or snorted depending on purity. Heroin is commonly seen in two different forms, one: as a brown hard toffee like substance known as Black Tar, and two: as a white powder known as China White. The majority of black tar heroin comes from Mexico well the vast supply of the white powder commonly known as china white comes from Indochina.
My back was killing me, and the Hillbilly Herion that my doctor prescribed wasn't doing a thing, so I copped me a bag of that black tar heroin my boy Juan be slinging.
