 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.

How cocaine addiction develops

When using cocaine manifests its psychostimulatory effect. A person experiences euphoria, a powerful burst of energy. There are self-confidence and a sense of comfort.

In order to re-experience this range of pleasant sensations, the drug begins to be used again and again. Someone manages to stay at the stage of episodic use for several years, someone becomes a drug addict in a few months.

If they have formed a psychological dependence in the absence of the drug in the blood of a person’s thoughts keep coming back to pleasant memories of narcotic intoxication. There is an obsessive desire to take a dose again to experience euphoria.

The use of powder occurs more and more often. At some point, dependence on psychostimulant becomes so pronounced that develop real “cocaine binges” when dependent drug use non-stop for several days. All this time he can not eat and not sleep. After the exhaustion of the body comes restless sleep, after which the depressed mood and an insatiable desire to take the drug.

Physical dependence on cocaine is slow and mild. Its formation is indicated by the following symptoms that occur after drug withdrawal: depression, a delirium of persecution, sleep disorders.

How drug addicts use cocaine

The first drug addicts chewed the leaves of the Coca plant.

The modern drug is used by addicts in the form of a white powder containing 80-95% of the active substance. This powder-cocaine hydrochloride, scattered on a horizontal surface in the form of tracks and retracted nose. Through the capillaries, the drug enters the bloodstream, and then with its current to the brain, where it has a psychostimulatory effect.

An alternative to the salt of cocaine is Coca paste, which is extracted at the first stage of the step process of producing a pure drug. It contains 40-80% of the active substance and is used for Smoking (usually mixed with tobacco or marijuana).

Another common way to use cocaine is to smoke crack. This kind of drug has the appearance of dense pinkish pieces. The name of crack was due to the characteristic sound that occurs when Smoking a cigarette.

Speedball is a mixture of cocaine and heroin used for intravenous administration. It has a rapid destructive effect on the psyche and body.

The dangers of cocaine

Cocaine interferes once in three neurotransmitter systems of the body: serotonin, dopamine, and noradrenaline responsible for many effects including the feeling of pleasure, psychological comfort, contentment themselves. Achieving peak sensations after taking a dose very quickly deprives a person of motivation to achieve goals, develop, build relationships with others. There is a rapid social exclusion, a rapidly developing mental changes, because of which the snowbirds are degraded and isolated from society.

All of these can lead to sudden death. Long-term use of psychostimulant causes severe heart disease (hypertrophic cardiomyopathy) and early atherosclerosis – the underlying cause of coronary heart disease and strokes.

Cocaine causes complete destruction of the nasal septum (inhalation through the nose). Its effect on the lungs leads to pulmonary bleeding, pneumothorax, non-infectious pneumonia (pneumonitis).

Similarly, the drug acts on the gastrointestinal tract, provoking the development of gastrointestinal bleeding and vascular thrombosis of the mesentery of the intestine with the development of necrosis (death) from emergency conditions.

In the case of the use of surfactants by expectant mothers, the risk of termination of pregnancy, intrauterine fetal death, birth of children with developmental defects increased dramatically, newborns are at high risk of stroke.

Cocaine addiction

The formed psychological dependence says that the person is sick with drug addiction and needs treatment.

Many novice consumers, struggling with addiction, are trying to create a system of “restraints”, for example, spend a strictly certain amount of drug per month or make a promise to use it no more often than once every few weeks. Very quickly, mental dependence on the drug pushes them to deal with themselves, and the drug is used more and more often. In the end, there are repeated “cocaine binges”.

Cocaine withdrawal

One dose of the drug does not last long – from 20 minutes to an hour, a maximum of two. Withdrawal usually develops after a “cocaine binge” and is characterized by a depressed and extremely anxious state up to deep depression and thoughts of suicide.

Overdose powder can lead to the death of patients. When it can occur:

  • Epileptic seizure;
  • Pulmonary edema;
  • Bleeding in the brain;
  • Coma;
  • Cardiac arrest and respiratory arrest;
  • Muscle breakdown (rhabdomyolysis).

If you suspect an overdose of the drug, you need to call an ambulance as soon as possible.

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.

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.

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

  • Arrhythmias
  • Bradycardia
  • ventricular premature contractions
  • Myocardial insufficiency
  • Elevated blood pressure
  • Elevated blood pressure
  • ventricular tachycardia
