This issue impacts not just people but also families, communities, and society at large, with far-reaching effects. The want to escape reality or find solace from mental distress is one of the primary causes of substance abuse. Drugs and alcohol are enticing to people who are looking for comfort because they offer momentary relief from tension, worry, or sadness. But this temporary solace frequently results in long-term addiction and makes their issues worse.

Reason for substance abuse:

1. Stress

Life is full of stress, which has different effects on different people. Some people experience tremendous stress, which can trigger unhealthy coping strategies like substance misuse. The excessive and hazardous use of drugs or alcohol, frequently as a way to dull or escape the effects of stress, is referred to as substance misuse. People may take drugs as a form of self-medication, which is one of the main ways that stress can lead to substance usage. When stress levels are high, people frequently look for solace and comfort. Substances like alcohol or drugs can provide a momentary sense of relaxation and reality escape, thereby easing anxiety or depression symptoms. Nevertheless, this respite is fleeting and may initiate a hazardous cycle of dependence. Furthermore, stress can impede judgement and decision-making, which in turn might lead to substance abuse. People could act impulsively and disregard the repercussions while under a lot of pressure. To deal with their difficult circumstances, they may try with drugs or alcohol. Chronic stress can also change the chemistry of the brain and make people more susceptible to addiction. Long-term exposure to stress chemicals like cortisol changes the brain's reward system, increasing a person's risk of developing addictive behaviours.

2. Depression

Depression is a severe mental illness that impacts millions of people globally. It is typified by enduring melancholy and pessimism as well as a lack of enthusiasm or enjoyment in activities. Regrettably, people who are depressed frequently turn to drugs in an attempt to find short-term solace for their mental suffering. Self-medication is one of the key reasons why people with depression consume drugs. When misery and despair overtake a person, they may resort to drugs or alcohol as a way out. Alcohol and opioids, for example, have the ability to momentarily dull the emotional suffering linked to depression, bringing about a feeling of comfort and relaxation. Furthermore, substance misuse might be considered a type of self-destructive behaviour among individuals experiencing depression. To deal with their bad feelings and self-loathing, people may turn to binge drinking or drug use. Their depression symptoms are made worse by this damaging pattern, which makes it harder to break the vicious cycle. Moreover, there exists data indicating a possible biological connection between substance addiction and depression. It has been discovered that neurotransmitters like serotonin and dopamine are involved in both disorders. Addiction-related behaviours as well as depressive symptoms may be influenced by imbalances in these substances. depression often serves as a cause for substance abuse due to various factors including self-medication and self-destructive tendencies.

Substance misuse also has a negative impact on one's physical health. Long-term drug or alcohol abuse can harm the liver, heart, and brain, among other important organs. It impairs immunity and raises the possibility of chronic illnesses including cancer and heart problems. The majority of drugs of abuse have detrimental effects on the cardiovascular system, according to the National Institute on Drug Abuse (NIDA). Drugs have the potential to trigger a heart attack as well as alter heart rhythm and pace. One medication that is well known to have a negative impact on the heart is cocaine; in fact, some doctors have dubbed it "the perfect heart attack drug.”

Effect of substance abuse on physical health:

1. Since the liver is the principal site of metabolism for many medications, the majority of pharmaceuticals pass through it. Because of this, the liver is especially vulnerable to harm from long-term drug misuse or overconsumption. Alcohol is the drug that can damage the liver the most out of all others.
2. Drug abuse also affects the kidneys because all drugs (or their metabolites) must eventually pass through the kidneys before being eliminated in the urine. The National Kidney Foundation (NKF) states that excessive alcohol use can cause an acute deterioration in renal function and pave the way for the development of chronic kidney disease. It can also have an impact on blood pressure and fluid balance. In addition, dehydration, dangerously high body temperatures (a common occurrence among ecstasy users), and muscle breakdown (rhabdomyolysis) are other ways that illicit drugs can damage the kidneys, either directly or indirectly.
   
3. Drugs have a variety of effects on the brain. Over time, some of the consequences may or may not be reversed. Drug usage may also be detrimental to the growing brain. Persistent marijuana use, for instance, is linked to a cognitive impairment that does not seem to entirely reverse even after quitting usage among those who started in their adolescence. Drinking alcohol has been linked to several markers of aberrant brain architecture, including diminished white matter microstructure and cognitive deterioration. There is a correlation between heavy drinking and an increased risk of dementia and extensive brain shrinkage. Additionally, abusing substances alters the way the brain processes rewards, leading to a gradual loss of association between naturally occurring and healthful activities and feelings that are sufficiently satisfying. The only thing that will produce the right amount of pleasurable reinforcement is the drug, and even then, the response will wear off over time and more will be required to experience the same reward.
   

Substance misuse also plays a role in societal problems like unemployment and crime rates. To support their addiction, addicts may turn to illicit activities, which could increase theft or violence in the community. Substance misuse also affects cognitive function and reduces productivity at work or school.

In conclusion, to properly treat the underlying difficulties, those who are battling with substance abuse must seek professional assistance. Through addressing the underlying reasons of their sadness and discovering more healthy coping strategies, people can escape the destructive cycle of substance misuse and strive towards long-term recovery and mental health.
