One of the reasons why we often say that drug testing is not credible is that all drugs do not stay in the human body for the same amount of time. In fact, some drugs remain in urine, blood, and hair longer than cocaine, ice and other potent drugs, such as marijuana.
Cocaine and its byproducts generally stay in the human system for one to four days after last use, but the substances can linger in the system even longer with chronic or heavy use of the drug.

How Long Does Cocaine stay in Urine?
Cocaine is detectable in a urine test for 3-4 days.
How Long Does Cocaine Stay in the Blood?
A blood test will detect cocaine for 1-2 days.
How Long Will Cocaine Show Up in a Saliva Test?

If it is necessary to detect the history of drug abuse, hair is an ideal biological test material. A hair test will detect cocaine for up to 90 days.
What is cocaine?
Cocaine is a local anesthetic (painkiller) and a powerful stimulant of the central nervous system (nerves that control activities in our body). Cocaine can be inhaled, injected or smoked (crack).
The chemical name for the pure cocaine is 8-methyl-3-(benzyloxy) 8-azabicyclo[3,2,1]octane-2-carboxylic acid methyl ester. Molecular formula C17H21NO4, molecule.
How Can Cocaine Abuse?
Cocaine abuse methods include nasal aspiration/spraying, smoking, and injection. Generally, the dose is used, and the nasal inhalation is 10-30 mg/time (individually reported to reach 50-200 mg, the typical user will inhale the dose separately with two nostrils); if using the injection method 10-20 mg/time.
The extent of the action of these toxins into the human body is closely related to the way they enter.
The bioavailability of cocaine by intravenous injection (the amount of drug absorbed by the body) is 100%, oral administration is 20%-30%, and nasal suction is 20%. %-30%, fuel absorption is 6%-32%.
Among them, the most common route is nasal inhalation, one nostril is blocked, and the other nostril is used to inhale cocaine crystal powder.
The cocaine powder is divided into a plurality of rows or columns by sharps such as a razor, and one gram of cocaine can be divided into about 25-50 rows, each of which acts 3-5 cm, and contains about 25-30 mg of commercially available cocaine.
This medicine is then inhaled through a straw made from US dollar bills or by means of a cocaine “spoon”. In this way, the drug is actually absorbed through the mucosa, and the peak plasma concentration can be reached in about 15 minutes, but the clinical onset time is very fast.
Intravenous use of cocaine hydrochloride for approximately 3-5 minutes. If you use the most popular free cocaine in the black market, you can have a strong euphoria in 1min when inhaled for 5-10min. Its half-life is also different.
The average half-life of intravenous injection was 45 min, the oral half-life was 48 min, and the half-life from nasal inhalation was 75 min.
The lethal dose is 0.5~1g orally, 30mg orally for allergy, 30mg for intramuscular or mucosal administration, and lethal blood concentration iare0.9-21mg/L.
Cocaine can be absorbed quickly no matter how it enters the body. The difference is only the length of time and the strength of utility. Its metabolism is mainly achieved through liver tissue and plasma.
What are the symptoms of cocaine drugs?
After taking cocaine drugs, although the suckers feel very happy and are filled with these pleasures, they seem to have been abnormal and appear to be mentally problematic to outsiders.
However, the smokers cannot feel it. As they were controlled by the illusion created by cocaine drugs, they had lost themselves.

- Increased common cold-like symptoms and/or nosebleeds.
- Signs of involuntary movements (i.e. muscle tics).
- Changes in concentration and focus.

As a result, the performance of various premature ageings, such as
- the disappearance of secondary sexual characteristics
- early morning hair
- teeth Lose
- less subcutaneous fat
- poor skin elasticity
- There is an old state that does not match the age
How did cocaine come from?
Cocaine is extracted: Researchers point out that drug dealers make cocaine, first by soaking coca leaves in petroleum derivatives such as kerosene, and then adding sodium carbonate, lime milk, or potassium permanganate, and filtering them to produce crude cocaine.
Cocaine, also known as coca cream. The coca paste is then combined with chloral hydrate, filtered and dried.

The behavioural characteristics of cocaine drug abusers revolve around the diversion of cocaine and even the loss of humanity for the consumption of cocaine drugs.
3. Infectious diseases
Intravenous cocaine drugs to abusers, bringing infectious complications, the most common pyogenic infections and hepatitis B, and worrying AIDS. In addition, it also damages the nervous system, the immune system, and is susceptible to various diseases.
4. Nervous System
Cocaine enters the central nervous system, which can quickly generate euphoria. The euphoria and mood-raising that can be trapped mainly depend on whether the plasma concentration is rising or falling because it is euphoric.
The decay rate is faster than the decrease in blood concentration. Cocaine is a convulsive agent. A single dose of cocaine can induce seizures, and repeated use can cause chronic epilepsy.
In addition, cocaine abuse can also cause intracranial haemorrhage, seizures, persistent or mechanical repetitive movements, ataxia and abnormal gait. The above abnormalities will gradually disappear after drug withdrawal.
5. Cardiovascular system
Cocaine easily causes coronary artery stenosis and increases platelet agglutination. Theatrical catecholamine acts on a and receptors of the peripheral and coronary vessels simultaneously, increasing peripheral blood pressure and increasing coronary vascular resistance.
These changes can increase the risk of Heart disease risk. Studies have shown that the amount of cocaine entering the heart has a direct relationship with the death of experimental animals. In addition, cocaine causes
- ventricular premature contractions
- Myocardial insufficiency
- Elevated blood pressure
- Elevated blood pressure
- ventricular tachycardia
The nasal mucosa is absorbed quickly after snorting cocaine. Because of its irritation and contraction of blood vessels, it is easy to form nasal cavity ulcers, loss of sense of smell, nasal valve atrophy, nasal septum perforation.
Cocaine acts on the medullary respiratory center, bronchial smooth muscle, and pulmonary vessels, leading to respiratory complications such as dyspnea, alveolar hemorrhage, cough, fever, pulmonary edema, pulmonary asthma and interstitial.
Impact on sexual function
Many cocaine abusers think that cocaine can increase sexual desire, but after serious addiction, they no longer pay attention to the pleasure of sexual intercourse and instead focus on how to satisfy their desire for cocaine.
After cocaine is injected intravenously or after inhalation, even if there is no stimulation of the sex organs, excitement can be induced or even spontaneous ejaculation. Sometimes it can even replace sexual partners.

Cocaine appears in the semen and may reduce the number of sperm, and increase the number of abnormal sperm. This can make it harder for you to get pregnant.
Cocaine Abuse Treatment
(1) drug treatment
Treatment during the detoxification period. In general, no alternative or declining treatment is required during cocaine detoxification.
Therefore, antidepressants and dopamine receptor agonists should be used mainly during this period to treat mental and physical disorders and withdrawal reactions due to overdose.
(2) Non-pharmacological treatment
Non-pharmacological treatment is a comprehensive treatment, including behavioural therapy, psychotherapy, rehabilitation, family therapy, group therapy and various preventive relapse treatments.
Non-pharmacological treatment is an indispensable and important process in the treatment of cocaine withdrawal. At the same time, it can effectively prevent relapse.
The study found that the main cause of relapse is that patients are psychologically eager to regain the euphoria when taking cocaine, so prevention of relapse should start with eliminating the patient’s “heart addiction.”
At the time of treatment, the therapist should analyze the various environmental, event, and human factors that induce relapse, and discuss and formulate corresponding solutions with them.
At the same time, patients should be encouraged to participate in regular self-help group activities. It enables it to gradually learn to deal with negative emotions and situations independently and to restore its social function.
In addition, family support and help are also essential to prevent relapse. Family members and drug addicts have the closest relationship.
As relatives, they open their hearts to drug addicts, embrace them with love and warmth, actively urge and help them to detoxify, patiently guide them out of the dark abyss of drug abuse, and rebuild confidence in life and Enthusiasm helps prevent relapsers from drug abusers.
Therefore, to stop cocaine addiction, it is best to go to the formal drug rehabilitation agencies for detoxification, especially for adolescents, their bodies are in the developmental stage, cannot withstand the pain caused by the dry ring; for long drug use, poison Those who are deeply addicted and whose individual willpower is not determined should also choose to go to a regular hospital for treatment.
About the method of detoxification after withdrawal of cocaine addiction, that is, the method of preventing relapse, patients should stay away from the places and friends who use drugs to avoid temptation, the room is comfortable and light, and the diet and living should be slow.
Return to normal, drink plenty of water, eat more beef, vegetables, fruits, eat more high vitamins to increase protein intake, do not eat spicy and irritating food, and insist on exercise, slowly return to normal life.
