The difference between drugs and poisons, the fundamental difference between drugs and poisons is wh

Drugs are substances that humans use to prevent, **, and diagnose diseases. In recent years, with the progress of science and the needs of human beings, the application of drugs has gone beyond the scope of disease prevention and treatment.

Poisons refer to substances that can cause functional or organic damage to the body and even endanger animal life when used in small amounts.

In fact, there is no absolute boundary between drugs and poisons, but only by the magnitude of the dose that causes poisoning. Drugs often cause poisoning if used in too large doses; Conversely, if the poison is used in small amounts, it can often lead to ** disease. For example, trichlorfon is a poisonous and highly toxic drug, but when taken in small doses, it can also drive away a variety of nematodes in the intestines of livestock and poultry.

However, it should be admitted that there is a difference in dosage and safety between drugs and poisons, and the dosage and safety of drugs are larger, while the dosage and safety of poisons are smaller, and special attention should be paid when using them. For example, some substances such as yam, honey, glucose, garlic, etc., are usually food, but they can be used to cure diseases, and then they are medicines. In short, there is a certain interrelationship between drugs, poisons, and foods, which must be identified and paid attention to when applied.

Drugs refer to chemicals that are beneficial to the human body or produce medical results that we expect after entering the human body, and are called drugs.

Poison is defined as follows: Anything that can act on the body in a small dose, causing damage to the body through chemical action and causing death, is called a poison.

There is no absolute boundary between drugs and poisons, but they can only be distinguished by the magnitude of the dose that causes poisoning. If the dosage is too large, it often causes poisoning; On the contrary, a small dosage can often lead to disease. As we all know, salt is an indispensable component of livestock feed, but if the amount is too large, it will cause salt poisoning in poultry; Trichlorfon is a poisonous and severe drug, but when taken in small doses, it can also drive away a variety of nematodes in the intestines of livestock and poultry.

Substances that are harmful to living organisms.

Under certain conditions, a small dose of a foreign chemical that can cause damage to an organism or cause an abnormal reaction of the organism is called a toxicant.

Poisons can be solids, liquids and gases, and after contact with or into the body, they can interact with the body and undergo physicochemical or biochemical reactions, causing functional or organic damage to the body, serious or even life-threatening. "Poison" also refers to poisonous things and vicious people.

Classification according to the chemical properties of the poison:

1) Volatile poisons. Poisons that may be separated by distillation or microdiffusion. Such as cyanide, alcohols, phenols, etc.

2) Non-volatile poisons. Poisons separated by organic solvent extraction. Such as barbiturates, hypnotics, alkaloids, morphine, etc.

3) Metal poisoning. Poisons that are separated by the method of destroying organic matter. Such as arsenic, mercury, barium, chromium, zinc, etc.

4) Anionic poisons. Poisons separated by dialysis or ion exchange. Such as strong acid, strong alkali, nitrite, etc.

5) Other poisons. Other poisons that need to be separated by a special method according to their chemical properties. Such as curareine, carbon monoxide, hydrogen sulfide, etc.

The above content refers to Encyclopedia - Poisons.

Poison refers to a foreign chemical that can cause damage to an organism or cause an abnormal reaction in a small dose under certain conditions, which is called toxicant.

Yes. Differences:

1. Different properties: Food refers to substances that can meet the normal physiological and biochemical energy needs of the body and extend the normal lifespan. Drugs are substances that are used to prevent, ** and diagnose diseases.

Under certain conditions, a small dose of a foreign chemical can cause damage to an organism or cause an abnormal reaction in the organism.

3. Different uses: When two drugs are used at the same time (drug-drug interaction) or certain foods are eaten (drug-food interaction), the effect of the drug can be affected by it. Food is a non-toxic substance that can be eaten and digested and absorbed to provide energy for the body's activities or regulate physiological functions.

Food: A substance that is intended for human or animal consumption is called food. Medications:

Refers to chemicals that can affect the physiological, biochemical and pathological processes of the body for the prevention, diagnosis, disease and family planning. Poisons: Under certain conditions, foreign chemicals that can cause damage to organisms or cause abnormal reactions in small doses are called poisons.

Hello, hypochondriasis psychological suspicion unhealthy psychological manifestations; Obsessive-compulsive disorder is an act of forcing oneself, a non-volitional manifestation; Anxiety disorder is a manifestation of emotional instability and anxiety, which requires the establishment of a positive and healthy mentality, the need to consciously maintain a relaxed mood, the need to participate in more targeted activities to delight one's mood, and the need to divert one's attention in time.

Hello! Drugs are substances used by humans to prevent and diagnose diseases. In recent years, with the progress of science and the needs of human beings, the application of drugs has gone beyond the scope of disease prevention and treatment, and poisons refer to substances that can cause functional or organic limb damage to the body at a small dose, and even endanger animal life.

First of all, the concept of "poison" is very broad, and we can simply divide it into two types: biological poison and chemical poison, so as to determine whether the poison is toxic or non-toxic according to whether the main chemical properties of the poison have changed.

Let's start with biological poisons, such as snake venom, which is actually a biological poison containing a variety of enzyme toxin proteins or molecular peptides. When exposed to high temperatures, strong acids or alkalis, the virus will gradually lose its original activity and no longer be toxic.

Therefore, this kind of biological poison becomes an expired poison after being left for a long time, and the toxicity may be weakened or become non-toxic. If these toxic proteins are converted into amino acids, they may also turn from poisons to nutrients, after all, there are only a few amino acids, and all of them are essential for living organisms.

However, chemical poisons are different, and there is basically no such thing as expiration. Like hydride, arsenic trioxide (arsenic, crane top red), etc. The chemical properties of this type of chemical poison are very stable and do not deteriorate easily even if left in the air for a long time.

It is only in an acid-base environment that other substances are formed, and the new substances that are formed are also toxic.

I don't know what your problem is, medicine is also poison, it is a medicine, and poison can fight poison with poison.

One is that it can ** a certain disease and make the sick person recover quickly. One is to make healthy people sick or die.
