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.

white powder(china white),mexian black tar.When i did it the first time i said,not me im stronger than that, i wont have a problem.Ya, chased the dragon til i was broke. Pawned anything and everything of slightest value that i owned n could possibly get my hands on.Its like missing an old friend when its not around or after smoke clears n u realise what youve done(i had this realization a month after being clean). then theres the sick you get when you dont have it...so sick all you have energy to do is think of or try to get more ...the chills,pain,and twitches....ugh! ....your brain does an autoswitch to junkie mode and you find yourself doing ANYTHING just to get a bit more...just one more time...just one more...just one more,i swear. If you like drugs i highly recomend staying away from this.....ive been clean about 6weeks and i still dont feel good and even though i know its horrible,i still miss her. Ahm,.... and i always will.Just one more time,...just one more....just one more,i swear...............
