Drug abuse can kill!


Drug abuse kills – My key question.

This will be my hypothesis.  I have chosen this key question because I have a lot of information and drug leaflets/books on drug abuse and how it kills its abusers.

I already have some leaflets on death caused by drug abuse, but I still need more information on this subject.  I’ll collect more information on drug abuse from my library (John Harvard library) and the chemist close to borough station. My mother will also get me some general drug information which I will use to explain the functions of different drugs, what their medical use it and what their abusive use does.

After the I finish the drug information, I will show some pictures of victims of drug abuse and a plotted map with the place which contains the most drug abusers.

Drugs information.

The types of drugs:

Barbiturates – Barbiturates are any group of drugs that depress brain function, they come from barbituric acid, a combination of urea and malonic acid.  Depending on the dosage or formulation, they can have a sedative, sleep-inducing, anticonvulsant or anaesthetic effect.  Short acting barbiturates such as thiopental are injected to induce rapid anaesthesia before surgery.  Phenobarbital, a long acting barbiturate, is prescribed with other with other medications to prevent epileptic seizures.  Other barbituric acids, like secobarbital, were used as antianxiety medication until the development of the tranquilliser.  Some are still used for a short-term treatment of insomnia.

Barbiturates are commonly abused drugs.  Producing symptoms similar to drunkenness: Loss of inhibition, violent behaviour, muscle incoordination, depression and sedation.  They are physically addictive and produce severe withdrawal symptoms; overdoses can cause profound shock, coma or even death.

Hallucinogen, any large number of natural or synthetic Psychoactive drugs that produce marked distortions of the senses and changes in perception. Hallucinogens generally alter the way time is perceived, making it appear to slow down. As the name suggests, hallucinogens may produce hallucinations, which are shape and colour shifts in the appearance of the outside world or, in extreme cases, the replacement of external reality with imaginary beings and landscapes. Hallucinogens may also lead to bizarre and antisocial thoughts as well as to disorientation and confusion.  Evidence suggests that hallucinogens work by inhibiting the availability of serotonin, an important neurotransmitter in the brain.  Hallucinogens are banned in the United States except in government approved research. The best known and most potent hallucinogen is lysergic acid diethylamide (LSD). Other hallucinogens include psilocybin, which comes from certain species of mushrooms, and mescaline, which comes from a cactus called peryote. These drugs are of medical interest because they produce effects similar to the symptoms of schizophrenia, a severe mental illness accompanied by distortions of reality. Some researchers believe that a hallucinogen-induced state can be used as a model to study schizophrenia.  Hallucinogens may be taken orally, injected, or, in the case of marijuana (a mild hallucinogen), smoked and inhaled. They usually take effect within an hour and cause increases in blood pressure, body temperature, and pulse rate as well as dilation, or enlargement, of the pupils of the eyes. These drugs may also cause nausea and numbness.  Individual reactions to hallucinogens are unpredictable, especially when these drugs are used recreationally--that is, for the pleasurable effects they produce and not for medical purposes. The experience of the drug may be pleasurable one day and highly disturbing the next, depending on the setting and circumstances in which the drug is taken and the individual’s personality and mood at the time. The effects of hallucinogenic drugs may last from a few hours to several days, and may recur months later in what are referred to as flashbacks.

Narcotics, originally applied to all compounds that produce insensibility to external stimuli through depression of the central nervous system, but now applied primarily to the drugs known as opiates; compounds extracted from the opium poppy and their chemical derivatives. Also classed as narcotics are the opioids, chemical compounds that are wholly synthesised, but which resemble the opiates in their actions.  The most important attribute of narcotics is their capacity to decrease pain, not only by decreasing the perception of pain, but also by altering the reaction to it. Although they do have sedative properties when used in large doses, ...
