Heroin Heroin /ˈhɛroʊɪn/ (diacetylmorphine or morphine diacetate, also known as diamorphine (BAN, INN[4]) and commonly known by its street names of H, smack, boy, horse, brown, black, tar, and others[5] is an opioid analgesic originally synthesized by C.R. Alder Wright in 1874 by adding two acetyl groups to the molecule morphine, which is found naturally in the opium poppy. It is the 3,6-diacetyl ester of morphine. Administered intravenously by injection, heroin is two to four times more potent than morphine and is faster in its onset of action.[6] Illicit heroin is sometimes available in freebase form, dulling the sheen and consistency to a matte-white powder.[7] Because of its lower boiling point, the freebase form of heroin is also smokable. As with other opioids, diacetylmorphine is used as both a legal, medically prescribed drug (e.g., as an analgesic, cough suppressant and as an anti-diarrhea drug) and a recreational drug, in which case the user is seeking euphoria.

Sport psychology Sport psychology is an interdisciplinary science that draws on knowledge from the fields of kinesiology and psychology. It involves the study of how psychological factors affect performance and how participation in sport and exercise affect psychological and physical factors.[1] In addition to instruction and training of psychological skills for performance improvement, applied sport psychology may include work with athletes, coaches, and parents regarding injury, rehabilitation, communication, team building, and career transitions. History[edit] Early history[edit] In its formation, sport psychology was primarily the domain of physical educators, not researchers, which can explain the lack of a consistent history.[2] Nonetheless, many instructors sought to explain the various phenomena associated with sport and physical activity and developed sport psychology laboratories. The birth of sports psychology in Europe happened largely in Germany. Franklin M. Applied sport psychology[edit]
Crack - Crack cocaine Crack cocaine ‘rocks’. Appearance and characteristics In purer forms, crack rocks appear as off-white nuggets with jagged edges,[3] with a slightly higher density than candle wax. Purer forms of crack resemble a hard brittle plastic, in crystalline form[3] (snaps when broken). Crack cocaine as sold on the streets may be adulterated or "cut" with other substances mimicking the appearance of crack cocaine to increase bulk. Chemistry In order for cocaine (in plastic bag at bottom) to be converted to crack, several supplies are needed. A close up of the "cooking" process that creates crack. Sodium bicarbonate (NaHCO3, common baking soda) is a base used in preparation of crack, although other weak bases may substitute for it. Coc-H+Cl− + NaHCO3 → Coc + H2O + CO2 + NaCl With Ammonium bicarbonate: Coc-H+Cl− + NH4HCO3 → Coc + NH4Cl + CO2 + H2O With Ammonium carbonate: 2(Coc-H+Cl−) + (NH4)2CO3 → 2 Coc + 2 NH4Cl + CO2 + H2O Psychological effects Physiological effects Addiction Health issues Crack lung Canada

Sativa - Cannabis sativa Common uses[edit] A sack made from hemp fiber Its seeds are chiefly used to make hempseed oil which can be used for cooking, lamps, lacquers, or paints. Plant physiology[edit] The flowers of the female plant are arranged in racemes and can produce hundreds of seeds. A Cannabis plant in the vegetative growth phase of its life requires more than 12–13 hours of light per day to stay vegetative. In soil, the optimum pH for the plant is 6.3 to 6.8. Cultivars[edit] Broadly, there are three main Cultivar Groups of cannabis that are cultivated today: Cultivars primarily cultivated for their fiber, characterized by long stems and little branching.Cultivars grown for seed which can be eaten entirely raw or from which hemp oil is extracted.Cultivars grown for medicinal or recreational purposes. Pharmacology[edit] The flower of a hybrid Cannabis indica plant Cannabis sativa, scientific drawing from c1900 Chemical constituents[edit] Difference between C. indica and C. sativa[edit] References[edit]

Cocaine Cocaine (INN) (benzoylmethylecgonine, an ecgonine derivative) is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.[5] The name comes from "coca" and the alkaloid suffix "-ine", forming "cocaine". It is a stimulant, an appetite suppressant, and a nonspecific voltage gated sodium channel blocker, which in turn causes it to produce anaesthesia at low doses. Biologically, cocaine acts as a serotonin–norepinephrine–dopamine reuptake inhibitor, also known as a triple reuptake inhibitor (TRI). It is addictive due to its effect on the mesolimbic reward pathway.[6] It is markedly more dangerous than other CNS stimulants, including the entire amphetamine drug class,[7] at high doses due to its effect on sodium channels, as blockade of Nav1.5 can cause sudden cardiac death. Unlike most molecules, cocaine has pockets[clarification needed] with both high hydrophilic and lipophilic efficiency, violating the rule of hydrophilic-lipophilic balance. Medical effects Acute
Methadone Methadone (also known as Symoron, Dolophine, Amidone, Methadose, Physeptone, Heptadon and many other names) is a synthetic opioid. It is used medically as an analgesic and a maintenance anti-addictive and reductive preparation for use by patients with opioid dependency. It was developed in Germany in 1937, mainly because Germany required a reliable internal source of opiates. Because it is an acyclic analog of morphine or heroin, methadone acts on the same opioid receptors as these drugs, and thus has many of the same effects. Methadone is mainly used in the treatment of opioid dependence. A number of pharmaceutical companies produce and distribute methadone. Medical uses[edit] Methadone maintenance[edit] The treatment of opiate addicted persons with Methadone will follow one of two routes. In Russia, methadone treatment is illegal. Analgesic[edit] As of 1. Adverse effects[edit] At dosage levels[edit] Adverse effects of methadone include:[citation needed] Withdrawal symptoms[edit]
