Heroine in nervous system This system involves neurons in the midbrain that use the

neurotransmitter called "dopamine." These midbraindopamine neurons project to another structure called thenucleus acumens which then projects to the cerebral

cortex. This system is responsible for the pleasurableeffects of heroin and for the addictive power of the drug.Other neurotransmitter systems, such as those related toendorphins, are also likely to be involved with withdrawalfrom and tolerance to heroin.

It affects the nervous system because it goes directly tothe brain and then it spreads all over through the spinalcore

Heroine history The discovery of the heroin demonstrates that it is a

painkiller; the German Bayer Company invented it as apainkiller in 1898, but it was stopped from being usedbecause it showed a lot of bad effects on the people. Even

though they tried to stop the damage, it was alreadydone; a new painkiller was developed. Since then, manyhospitals have stopped the usage of heroin as a painkiller,but other ones still use it as a painkiller. That shows that

the heroin is a painkiller, and a one that may be veryeffective.

Now it is a fact that people use as a psychoactive drug


18/23

also they are psychological. They are expressed ininsomnia, attacks of panic and mental functions andbecause of this reasons people must think twice after

Analysis Heroin is one of the most addicted drugs in the whole

world. Is a substance that is very dangerous for humanbeings. Certainty, as we see heroine attack the nervoussystem, it starts producing a chain of reactions in our body

causing even death. This substance had been called bypeople in many ways, but we conclude that its perfectname could be HEROIN, A TRIP WITH OUT RETURN.


21/23

According to the background theorical research that wasdone, the heroin is a painkiller, and sometimes it is used bythe hospitals. Even though it is a painkiller, it has a lot ofbad effects in both long and short terms. This research

also shows that smoking and sniffing heroin is not aseffective as injecting it, but all three of them are highlyaddictive. Also it showed that the heroin started as amedical treatment as other drugs that are very harmful as

cocaine.
