The origin of poisoning

In forensic practice more common household poisonings resulting from an accident or deliberate actions. Much less often - poisoning in medical practice in the use of drugs (drug poisoning) or manufacture in violation of safety (occupational poisoning), as well as food poisoning resulting from ingestion of food.
In the modern world increases the risk of acute poisoning due to accidents at chemical plants and storage facilities, in case of accidents during the transport of toxic substances.
In forensic practice have to deal with poisonings, including fatal, occurred on the background of drug and substance abuse.
Drug addiction - the attraction to the permanent reception in increasing quantities of narcotic drugs due to persistent mental and physical dependence with the development of abstinence. Leads to profound changes of personality and other mental disorders, and disorders of the internal organs. For abuse inherent in pathological addiction (craving) to the drug. To drug abuse is abuse of only those substances and preparations, which are included in the List of drugs approved by the order of Ministry of health of the USSR. Drugs are under special control of the state and withdrawn from sale.
Substance abuse indicate systematic abuse of those substances (usually drug), which are not included in the List of drugs. In most cases, with substance abuse are marked with the same symptoms of the changed reactivity, as in drug addiction (change of tolerance, mental and physical dependence).
Substances that cause addiction and pain of addiction to them, very different chemical structure and pharmacological effect. The most common misuse of the following substances: (a) opium, its products (omnopon, tincture of opium), some alkaloids and derivatives of opium (morphine, codeine, dionin and others), synthetic drugs with morphine-like effect (promedol, fentanyl, penadon); b) hypnotics means: barbiturates (barbanel, Medina, Nembutal, hexobarbital, Verona, luminal and others), drugs that are non-derivative of barbituric acid (exeron, admin, bromural and other); C) hashish (synonym: cannabis, plan, marijuana)contained in various cannabis; d) stimulants (caffeine, amphetamine, meth, and others). Pelinakman possible reception of two or more drugs, different in their activity. So, opium addiction can be combined with the abuse of drugs means that taking cannabis; barbituratami alcohol and abuse of certain psychotropic substances and other
The abuse of drugs and stimulants, not included in the List of drugs, should be considered as substance abuse. More rare types of substance abuse is systematic bringing themselves in a state of intoxication with vapor of gasoline, acetone, various household chemistry, containing essential oils. To such unusual ways to change your mental state is usually used psychopaths, less frequently alcoholics and drug addicts.
In medical and legal practice, there are three main types of intoxication: alcohol, drug and toxic. Examination of these types of intoxication produced by the doctors - psychiatrists-narcologists, neurologists, and in some cases by doctors of other specialties. Moreover, the establishment (diagnostics) of intoxication and his character is based on the detection of clinical signs, and the presence in the body testify of specific substances or groups of substances causing intoxication.
You should also remember about the possibility of deliberate application of a number of potent drugs to bring the victim in a helpless state by mixing drugs for alcoholic beverages, juices and other Coming in this helpless condition is associated with the development of short sleeping pills, drugs, at least - komfortnogo effect, often without any consequences for the health of the victim. Upon receipt of such victims in hospital (even in stage of the expressed clinical manifestations) in Toxicological analysis of blood and urine frequently found only traces of sleeping pills, psychotropic or other drugs in the urine or (more often) they are not detected. This is due to the fact that the intake of alcohol the effects of their apparent in such small doses, which are rapidly eliminated from the body, or simply do not reach the threshold of sensitivity of laboratory diagnostic methods. In some cases, victims are not treated in specialized hospital, and look around once doctors, ambulances, clinics, and admission departments of General hospitals. Thus poisoning they have not always diagnosed and often their condition "written off" to alcohol intoxication, predecisional syndrome, a breach of cerebral circulation, etc.
Became known cases of acute poisoning the clonidine because of the intentional adulteration of it in a variety of alcoholic and non-alcoholic drinks, as well as the use of eye drops for glaucoma, representing a solution of clonidine. In the body of the victims, as a rule, gets a dose of clonidine times higher than therapeutic. Coming in this helpless condition due to a sharp fall in blood pressure and sleepiness (in the face of intoxication).
In medicine there is no single generally accepted classification of poisons. In forensic practice adopted systematization of poisons, which was based on the ability of poisons cause a sharp defeat in the field of primary their impact (local poisons), or to be toxic effect only after their intake (resorptive poisons).
