[3] [5] This preventable pathology can be fatal if it leads to respiratory depression, a lethal condition that can cause hypoxia from slow and shallow breathing. [3]
He originally was looking for a non-addictive alternative to morphine. Heroin was sold by Bayer Laboratories to doctors as a 'sedative for coughs' in 1898 after it was re-synthesized by chemist ...
The production of black tar heroin results in significant amounts of 6-MAM in the final product. [citation needed] 6-MAM is approximately 30 percent more active than diacetylmorphine itself, [citation needed] This is why despite lower heroin content, black tar heroin may be more potent than some other forms of heroin. 6-MAM can be synthesized from morphine using glacial acetic acid with an ...
For every 455 g (16.0 oz) of morphine, approximately 311 g (11.0 oz) of crude heroin base can be extracted. This is then sent to a heroin-refining laboratory. Heroin Number 3 is created by mixing crude heroin base with hydrochloric acid, resulting in heroin hydrochloride, which is less than 40% pure and is typically consumed locally by smoking.
The main side effects heroin causes on appearance according to New Health Advisor are: Weight loss due to loss of appetite, or because a heroin abuser may not prioritize eating.
