[...] In the next step, ketamine is hydroxylised in 6hydroxy-norketamine. This substance is glucuronidated, which means that it is condensed with glucuronic acid to become solvable and be eliminated in urine or bile. Drogue: Let's now move on to the last part: The misuse and negative effects. Unfortunately, ketamine is used like hard drug. Sure, it is completely banned and punishable by the law. Indeed, this disruptive of nervous system causes powerful hallucinatory effects wanted by drugdependant. It's a drug which is more and more consumed in nightclub, rave-parties and free-parties.

[...] This graph has a scale from 0 to 3. As you can see, Ketamine cause much more physical harm with a point at 2 compared at mostly of other drug like LSD, alcohol, tobacco, cannabis and ecstasy but less that heroin, cocaine. However, Ketamine causes less dependence and less social harm with respectively 1.5 and 1.7 compared to alcohol, tobacco, heroin and cocaine but more than other drugs like LSD, ecstasy. Conclusion I'm now coming to the end of my presentation. [...]

[...] I am currently doing a master's degree in molecular chemistry at the university of . I am going to talk about the ketamine. My talk will be in 3 parts. First of all, I am going to present Ketamine and medical use. Then, I will explain the ketamine synthesis and its metabolism in the body. Finally, I am going to highlight its misuse and the adverse effects. My presentation will take about 10 minutes. Please could you keep any questions until after I've finished. Presentation Let's now move on to the first part. [...]

[...] The real name of this molecule is ketamine chlorhydrate. As you can see on this slide, Ketamine is an organic compound and a small molecule composed of an amine, a cyclohexanone and a benzene with a chlorine in alpha position. It is used in medical field but also in veterinary field for this faster anaesthetic action. It's also a powerful painkiller and antidepressant which can be administered by different ways: intravenous, subcutaneous and intramuscular. It is important to remember that Ketamine must be used only in medical environment because of plentiful secondary effects which I will explain to you in the last part. [...]
