Four Main Categories of Psychoactive Drugs
The four main categories of psychoactive drugs are â€“ stimulants, Depressants, narcotics, and hallucinogens. These drugs have an impact on the brain by affecting the neurotransmitter functions. Neurotransmitters are the chemicals that affect how anxious, tired, scared, happy hungry, thirsty you feel. They also affect the cognitive state of the person. This in turn has an effect on the psychological experiences by altering the sensory perception, moods, behavior and thinking pattern. Let us look mainly at the stimulants here which include chemicals from caffeine and nicotine to cocaine and crystal myth. These stimulants block the re-absorption of the neurotransmitters like dopamine and serotonin and hence can cause increased energy, which sometimes, takes the form of anxiety and panic.
Modafinil is a stimulant drug which causes wakefulness in a person. It is clinically being prescribed by doctors to treat sleep disorders like narcolepsy and obstructive sleep apnea. It is also used to treat ADHD, multiple sclerosis and a few other ailments like treatment resistant depression. This drug is also taken by many people to enhance their cognitive abilities. Many studies have come to the conclusion that modafinil enhances the ability of a person to do complex tasks while it has little or no impact on simple tasks. At the same time, it is also useful in treating fatigue and lack of concentration. This is the reason that many people take modafinil in order to accomplish complex tasks like studying for exams. IT helps the students to stay awake longer and learning ability is also improved. This drug has a similar effect that caffeine and nicotine have on the brain, but is much more potent. Based on the different laws and regulations of selling modafinil in different countries, you can either buy modafinil online or offline.
Depressants include alcohol and all sleep medication. They help the brain and body to relax and lower the cognitive ability. Although in a small amount alcohol is good for the body and helps you relax, but consuming too much of it and that too for a longer duration can lead to alcoholism which causes depression, obsessive behavior and other psychological disorders. As far as sleeping pills are concerned, they should never be taken without the guidance of a qualified doctor.
