crack là gì - Nghĩa của từ crack

crack có nghĩa là

As a rule of thumb, it is profoundly unwise to take crack-cocaine. The brain has evolved a truly vicious set of negative feedback mechanisms. Their functional effect is to stop us from being truly happy for long. Nature is cruelly parsimonious with pleasure. The initial short-lived euphoria of a reinforcer as powerful as crack will be followed by a "crash". This involves anxiety, depression, irritability, extreme fatigue and possibly paranoia. Physical health may deteriorate. An intense craving for more cocaine develops. In heavy users, stereotyped compulsive and repetitive patterns of behaviour may occur. So may tactile hallucinations of insects crawling underneath the skin ("formication"). Severe depressive conditions may follow; agitated delirium; and also a syndrome sometimes known as toxic paranoid psychosis. The neural aftereffects of chronic cocaine use include changes in monoamine metabolites and uptake transporters. There is down-regulation of dopamine D2 receptors to compensate for their drug-induced overstimulation. Thus the brain's capacity to experience pleasure is diminished.

Otherwise known as crack-cocaine, this illegal drug is a mixture of two parts cocaine and one part baking soda. This chemical process reverts the powder-cocaine mkaing process by one step, producing a smokable form of the naturally found alkaloid cocaine. Because of its nature as an inhalable substance, the high is quicker and more intense, leading to a larger number of addicts. In present society, it is considered to be much more distasteful to use crack-cocaine then powder-cocaine as crack is mainly viewed as a drug for poor people whereas powder cocaine is used by a richer constituancy. Contrary to popular belief, crack-cocaine is not freebase cocaine. Freebase cocaine is a mixture of cocaine, ether, and other dangerous and combustable materials. Baking soda was replaced as the ingredient in the 1980's to make production easier and less dangerous. Either way, crack and freebase cocaine produce the same smokable form of the drug.

Example

crack có nghĩa là

'Freebased' cocaine.

What is popularly known as 'cocaine' is actually the chemical compound 'Cociane Hydrochloride'. This substance is nuetral, the 'Cocaine' part being a base and the 'Hydrochloride (Hydrochloric Acid)' being an acid. It is impossible to smoke Cocaine Hydrochloride because upon being heated, it simply decomposes.

So, some brilliant dopehead realized that the way to make it possible to smoke Cocaine is to 'free the base'. To do this, you mix 1 part cocaine and 1 part baking soda (carbonate of soda) with water. The hydrochloric acid detaches from the cocaine in order to react with the baking soda, producing water vapor and salt. Wait for the water to evaporate, and you have a 'rock' or crack, usually white, yellow, or pea-colored. You will wind up with slightly more crack than you had cocaine.

Street-crack is usually adultered and contains many chemicals in it besides freebased cocaine. To at least partially remove these chemicals, set your rock on a hard surface, heat with a lighter until melted, and then scrape off your slightly more pure crack with a razor blade when it dries.

Crack is much more addictive than cocaine, because it absorbed faster. The lungs have a much larger surface area than the mucas membrane of your nose, so immediately after taking a hit of crack, you'll get the high. It's gone almost as fast, leaving all the dopamine in your nerve synopses screaming "MORE CRACK!" You will then smoke more crack. Unless you are a millionaire, you will probably run out of crack before you die of chronically high blood-plasma levels, so you will most likely start off by selling all your clothes and your house, before resorting to crime and prostitution in order to get a fix.

Have fun, kids.
