The nervous system controls and organizes all parts of the body. The brain receives all the messages and tells the respective body parts to do their jobs. Neurons pass through the nervous system to receive and transfer messages in the form of electrical impulses. In order for the brain to receive all messages, a special chemical known as neurotransmitters carries the messages to the brain. There are many types of neurotransmitters such as dopamine, GABA, insulin, etc. Neurotransmitters are found between small spaces between neurons called synapses. A neurotransmitter works by moving rapidly along the synapse and joins with sites on the other sides to restart the electrical impulse. They are then broken down and receive new messages. Neurotransmitters are important for our body to provide responses, but they can be damaged or destroyed by certain things such as medications. There are many drugs that can affect them, an example is cocaine and caffeine. There are many effective solutions for these drugs, but they have not been proven to completely eliminate the effects on the body. Drugs are substances that disturb this delicate balance, because they have "access keys" that allow them to open certain "locks" located between neurons. . The brain automatically adapts to these substances coming from outside the body by producing fewer natural "keys". Cocaine is a type of drug that affects dopamine, a neurotransmitter linked to emotions, while norepinephrine is linked to alertness. Cocaine is considered an illegal drug in most countries, but some consider it legal. Although cocaine is an illegal drug, ancient people once considered it a medicine to cure many diseases. Cocaine is absorbed into dopamine and... middle of paper... without any drugs some violence etc can occur. The economic impact is low on the workforce as many people are taking treatments, students taking drug abuse treatments would not be able to study, a higher unemployment rate, etc. Some health impacts of these treatments include anxiety, headaches, depression, etc. Taking drugs has a bad influence on society. It can harm people's lives and even change the way they behave. By not taking illegal drugs the human body can function more effectively and can have a better influence on future society. Not taking drugs can do a lot: it can make neurotransmitters work, it can have a good influence on society, it can make a country have fewer crime scenes, and it can also make our body grateful to us by not destroying them etc. drugs just to be popular or just to show off: simply by being a good citizen we can be popular.
