Many people are addicted to drugs; they ingest some commonly abused drugs such as alcohol, illegal substances, prescription drugs, if we include nicotine and caffeine, we will come to realize that most people are already drug addicts even unknown to them.

Psychoactive drugs

Psychoactive drugs are drugs or chemical substance that can alter the brain function. They are also known as psychotropic substances which is a chemical that acts upon the central nervous system where it affects the brain function, resulting in temporal changes in perception, mood consciousness and behavior. These drugs are used for different purposes; they can be used in controlling a severe pain or as a therapy for mental and emotional disorders. The intake of these drugs repeatedly can lead to addiction which results in drug abuse.

Use and abuse of psychoactive drugs

The right ones can provide calm relief from severe pain or a headache and can also lift people’s mood who are depressed; some can help children in deficits regarding attention such as forgetting their homework, daydream and act without thinking, making them pay attention more and learn better. But most of these drugs can also be used for recreational purposes to alter their level of consciousness, mood, behavior, physical sensation, and thoughts in ways that users of these drugs believe to be enjoyable and these recreational purposes produces negative consequences.

Psychoactive drugs divided into various categories, and they are:

They also can produce sluggishness and lethargic behavior ( symptom causing you to feel sleepy, fatigued or sluggish). Examples are alcohol, heroin, sedatives, analgesics, methaqualone, etc.
• Hallucinogens: These are categories of drugs that change the feelings, perception, and can result in hallucination such as seeing or hearing imaginary things. Examples are ketamine and mescaline, psilocybin(also known as a magic mushroom), etc.
• Others: There are other categories of psychoactive drugs, there are some that have the combination of two or more of the groups discussed above. Other psychoactive drugs that fall under this category may include cannabis, opioids, an, etc.

A crack is a form of cocaine. It is a stimulant that brings high and rapid euphoria.

It can quickly be provided, transported and cheaper to buy than cocaine. It is smoked, sniffed or injected. Users prefer smoking the drug than injecting or inhaling it because smoking produces a faster and more intense effect and through smoking of the drug, the substance goes straight to the bloodstream thereby causing addiction.

Try to picture the world with human beings without consciousness. How can one live in such a world, consciousness is an essential part of human life which psychologists and philosophers have in time past always wanted to understand. Over the century, researchers on the topic of (consciousness) have mostly been studied. The qualia of consciousness are unable to reach direct observation. But psychologist has been able to examine the different ways people alter their level of consciousness.

Today, Psychology scientist have been making significant progress in understanding the biological foundations of consciousness. So avoid drugs because it affects our behavior and in turn affects the society.
