How Drugs Impacts our brain and body

Our bodies, as the great machine ever constructed, gets damage by the misuse of substance, that is call damaging addictions. The addiction is the cause for the destruction of this amazing machine that starts when we force it to react in the way that is not supposed to work. Everything starts in our brain: When dopamine is diminished due to the mistreatment of our brain instruments (opium receptors, neurons, etc…) that controls the release of this very important substance, that tell us “this feels good”. One will uncontrollably became obsess with an unreal “survival” mode, that is call addiction. Drugs can accelerate dopamine into our body in an irregular speed making our brain violently abused and in consequence damage.

Our body will also suffer due to the injury of the brain. If the brain is mistreated will make us feel unmotivated to do or act in a healthy way affecting the health of our body too. The mistreatment of our brain and body creates the environment of the addict. The addict, nonstop, will not comprehend how or why, the nail on their head like the short video that we saw last class, makes them feel unmotivated to create a healthy life for themselves or anyone around them.

Answer 1

Every cell has its own specific receptors. When we take drugs, they are meant to be oriented against specific groups of cells via their specific receptors. After sensitizing these receptors, different cells respond in different ways. Some respond by secreting different substances into the bloodstream, some by proliferation, some by inhibiting the growth of themselves and many other ways.

Drugs stimulate this mechanism of cells which is disrupted due to any pathological condition like any disease and bring back the normal balance in the body. Drugs acting on the central nervous system bring about changes in the brain cells which we call it Neurones.

It causes an increase or decrease in the secretion of neurotransmitters like dopamine, Acetylcholine, gamma-aminobutyric acid and other. Some of these neurotransmitters are excitatory which causes elevation of mood, agitation, hallucinations, etc. Some of these neurotransmitters are inhibitory and cause depression, loss of interest in surroundings and etc. In this way drugs act on brain.

Overuse of drugs causes excess stimulation of these cells and inabilty of the liver to metabolise that drug to excrete it. And that leads to side effects and toxicity of that drugs.

In these way drugs impact our brain and body.
