As morphine is generally as hard or harder to divert than oxycodone in a lot of cases, morphine in any form is uncommon on the street, although ampoules and phials of morphine injection, pure pharmaceutical morphine powder, and soluble multi-purpose tablets are very popular where available.Morphine is also available in a paste that is used in the production of heroin, which can be smoked by itself or turned to a soluble salt and injected; the same goes for the penultimate products of the Kompot (Polish Heroin) and black tar processes. Poppy straw as well as opium can yield morphine of purity levels ranging from poppy tea to near-pharmaceutical-grade morphine by itself or with all of the more than 50 other alkaloids. It also is the active narcotic ingredient in opium and all of its forms, derivatives, and analogues as well as forming from breakdown of heroin and otherwise present in many batches of illicit heroin as the result of incomplete acetylation. Names
Morphine is marketed under many different brand names in various parts of the world. It was formerly called Morphia in British English.Informal names for morphine include: Cube Juice, Dope, Dreamer, Emsel, First Line, Gods Drug, Hard Stuff, Hocus, Hows, Lydia, Lydic, M, Miss Emma, Mister Blue, Monkey, Morf, Morph, Morphide, Morphie, Morpho, Mother, MS, Ms. Emma, Mud, New Jack Swing (if mixed with heroin), Sister, Tab, Unkie, Unkie White, and Stuff.MS Contin tablets are known as misties, and the 100 mg extended-release tablets as greys and blockbusters.
Psychological withdrawal from morphine is usually a very long and painful process. Addicts often experience severe depression, anxiety, insomnia, mood swings, amnesia (forgetfulness), low self-esteem, confusion, paranoia, and other psychological disorders. Without intervention, the syndrome will run its course, and most of the overt physical symptoms will disappear within 7 to 10 days including psychological dependence. A high probability of relapse exists after morphine withdrawal when neither the physical environment nor the behavioral motivators that contributed to the abuse have been altered. Testimony to morphines addictive and reinforcing nature is its relapse rate. Abusers of morphine (and heroin) have one of the highest relapse rates among all drug users, ranging up to 98% in the estimation of some medical experts. Toxicity
A large overdose can cause asphyxia and death by respiratory depression if the person does not receive medical attention immediately. Overdose treatment includes the administration of naloxone. The latter completely reverses morphines effects, but may result in immediate onset of withdrawal in opiate-addicted subjects. Multiple doses may be needed as the duration of action of morphine is longer than that of naloxone.The LD50 for humans of morphine sulphate and other preparations is not known with certainty. One poor quality study on morphine overdoses among soldiers reported that the fatal dose was 0.78 mcg/ml in males (~71 mg for an average 90 kg adult man) and 0.98mcg/ml in females (~74 mg for an average 75 kg female). It was not specified whether the dose was oral, parenteral or IV.
