Caffeine is a xanthine alkaloid compound that acts as a psychoactive stimulant and diuretic in humans. The word comes from the French term for coffee, café.[2] Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all these names are considered chemical synonyms for the same chemical compound.
Caffeine is completely absorbed by the stomach and small intestine within 45 minutes of ingestion. After ingestion it is distributed throughout all tissues of the body and is eliminated by first-order kinetics.
The half-life of caffeine—the time required for the body to eliminate one-half of the total amount of caffeine consumed at a given time—varies widely among individuals according to such factors as age, liver function, pregnancy, some concurrent medications, and the level of enzymes in the liver needed for caffeine metabolism. In healthy adults, caffeine's half-life is approximately 3–4 hours. In women taking oral contraceptives this is increased to 5–10 hours, and in pregnant women the half-life is roughly 9–11 hours.Caffeine can accumulate in individuals with severe liver disease when its half-life can increase to 96 hours. In infants and young children, the half-life may be longer than in adults; half-life in a newborn baby may be as long as 30 hours. Other factors such as smoking can shorten caffeine's half-life.
Caffeine is metabolized in the liver by the cytochrome P450 oxidase enzyme system (specifically, the 1A2 isozyme) into three metabolic dimethylxanthines, which each have their own effects on the body:
* Paraxanthine (84%): Has the effect of increasing lipolysis, leading to elevated glycerol and free fatty acid levels in the blood plasma.
* Theobromine (12%): Dilates blood vessels and increases urine volume. Theobromine is also the principal alkaloid in cocoa, and therefore chocolate.
* Theophylline (4%): Relaxes smooth muscles of the bronchi, and is used to treat asthma. The therapeutic dose of theophylline, however, is many times greater than the levels attained from caffeine metabolism.

Caffeine addiction is for real and to compose matters further intimidating for the passionate coffee drinker or cola fan, caffeine employs the similar property as alcohol, LSD, cocaine, sparkler methamphetamine, nicotine, opioids, benzodiazepines, and other major drugs. This makes caffeine the widest used psychoactive drug in the earth.

Individualized drug recovery treatments counseling focuses directly on reducing or stopping the addict's illicit drug use. It also addresses related areas of impaired functioning such as employment status, illegal activity, family/social relations as well as the content and structure of the patient's recovery program.

Caffeine Pills -Effects, Withdrawal and Addiction
Caffeine pills are used worldwide as weight loss remedies and as stimulant drugs. Caffeine pills are the latest rage in the health and fitness industry as well, and they are used extensively as they are known to improve alertness and boost energy in human beings.
Caffeine pills also have side effects, just like any other type of medication, such as increased heart palpitations, headaches, restlessness, insomnia, psychomotor agitation, depression, irritability, disorientation, lack of judgement, peptic ulcers, loss of social inhibition, respiratory alkalosis, hallucinations, erosive esophagitis, etc.
If you ignore the headaches, a major symptom of caffeine withdrawal, that will just make you more tempted to return to the full-caffeine routine, so I recommend you to use pain relievers instead. Just be aware that some pain relievers, like Excedrin, contain caffeine, so you must include that when figuring out your daily caffeine intake! Reducing your consumption of caffeine gradually will also minimize the risk of suffering caffeine withdrawal.
Some people don´t even think about the word “addiction” when they refer to caffeine. As a matter of fact, caffeine is an addictive drug and Caffeine Addiction is a reality in our world that must be treated just like any other addiction.
Some other people frequently say they are "addicted" to caffeine in much the same way they say they are "addicted" to shopping, working or television, and the term "addiction" actually refers to a strong dependence on a drug characterised by severe withdrawal symptoms, tolerance to a given dose and the loss of control or the need to consume more and more of the substance at any cost.
