Modafinil is a white, crystalline powder produced for the first time in 1999. It is used for the establishment of a so-called “cognitive enhancer” in the market. Modafinil is a stimulant, which gives you the ability to focus more easy.
Originally, the drug was developed against the sudden sleep attacks of narcoleptics. The effect is that the modafinil in narcoleptics reduces the sleep attacks by about one per day.

In performance sports, fatigue and exhaustion are certainly the greatest enemies of sporting success.
In order to counteract this, some athletes used Modafinil to gain an illegal advantage. Already in 2003, sportsmen were caught using the forbidden substance. So for example the US American sportsman Calvin Harrison (World Champion and Olympian winner in the relay) and Kelli White, a sprinter from the USA.

The greatest danger is in long-term use is that many consumers quickly get used to regular “tuning” and thus develop a psychological dependency. In the US, sales of approximately 1 billion dollars were already achieved in 2008.

If a healthy person accepts modafinil as a stimulant, it is very often reported that the brain is more powerful. Various tests with placebos and modafinil always resulted in a performance increase of the short-term memory of the Modafinil probands and in a reduction of the creativity.

Today Modafinil is used in the warfare to keep the soldiers awake and concentrated. It is also known that it has been prescribed for overcoming the jet-lag in the case of many-traveling persons.

The effect of modafinil can last up to 12 hours, which is a longer time of action than that of amphetamine and caffeine.
One of the effect is to influence the central serotonergic pathways and thus to enhance the effects of noradrenaline on central alpha-1 receptors.

The greatest danger is in long-term use, as many consumers quickly get used to regular “tuning” and thus develop a psychological dependency.

In Germany, Modafinil fell under the Narcotics Act by the end of February 2008. Since March 2008, it is available as a prescription drug in the pharmacy.
