Drug abuse is a serious problem, which is capable of not only causing death to the one using it, but create a havoc in the lives of those who are associated with that person too. There have been plenty cases, whether it is Matthew Perry or the recent death of Liam Payne, which is in trial currently.

It is also a problem in the US and is emerging as one of the health concerns that could destroy families and society. One of the most alarming aspects of drug abuse is also its impact on public safety as well as increased crime rates. Drugs also take a heavy toll on healthcare systems as emergency departments frequently encounter cases of drug overdoses, which puts the burden on medical professional who have the strain the limited resources available.

There are also long-term health impact due to drug abuse, which includes organ damage, infectious disease, mental health disorders and rise in healthcare cost.

Are there any specific drugs which are most abused in US?

Yes. There are commonly used drugs, which also includes prescribed painkillers like oxycodone, hydrocodone, and fentanyl, as well as illicit substances like heroin. As per recent data, opioid abuse has also reached alarming levels which has affected millions of Americans.

Here are the most abused drugs in the US:

Stimulants

They are used to increase alertness, attention, and energy. They also have a high potential for abuse due to the euphoric and performance enhancing effects. Cocaine and methamphetamine are notable stimulants frequently abused in the US. As per 2019 data, 10.3 million people reported to misuse stimulants in the previous year.

Depressants

These substances are used to slow down brain activity and induce relaxation. Benzodiazepines is one of the commonly prescribed medicine. Around 4.8 million individuals in the US have misused this drug.

Other misused drugs and its affects on the health:

Opioids:

It could lead to slow breathing and heart rate. It can also increase the risk of overdose and respiratory failure, constipation and a weakened immune system.

Stimulants:

It can elevate heart rate and blood pressure. It could also increase body temperate and lead to an irregular heartbeat. Furthermore, one can experience loss of appetite and weight loss.

Cannabis:

This can alter perception and coordination. People who consume it often have red eyes and a dry mouth. This can increase appetite, sometimes the "munchies" can reach to a point of no return and it could impair memory and cognitive function.

Benzodiazepines:

It could lead to sedation and drowsiness and an impaired coordination and balance. There also could be memory problems and confusion, along with respiratory depression, when combined with other depressant substance.

Alcohol:

This could lead to slurred speech, impaired condition, poor judgment and decision-making, liver damage and cirrhosis and an increased risk of accidents and injuries, which is the 3rd most leading cause of death in the US.

Additional Negative Impact: Social and psychological

Substance abuse impairs job performance and reliability, leading to frequent absenteeism, reduced productivity, and even job loss. This further leads to financial instability, strained relationships, and a cycle of dependency.

Athletes who spend years training their bodies undergo remarkable physiological changes. Athlete's heart is one of them. It becomes stronger, more efficient, and sometimes even larger. This natural adaptation is known as athlete's heart, a condition that is completely normal in most cases but can occasionally resemble serious heart disease.

What Is Athlete’s Heart?

Understanding the difference between a healthy athletic heart and an underlying cardiac disorder is crucial, especially as awareness grows around sudden cardiac deaths in young athletes.

HealthandMe spoke to Dr. Ruchit Shah, Interventional Cardiologist at Saifee Hospital, Mumbai, who said, “If a person exercises too much, normally more than 60 minutes in most days of the week for a prolonged period of time, the body's need for oxygen and for blood to supply the oxygen rises significantly. This can often be seen in the very intense training regimens of competitive athletes. The heart muscle responds to this extra demand by getting "conditioned" and thickening with time.”

Just like skeletal muscles that get bigger and thicker and with training and exercise, the heart muscle can get bigger and thicker too.

Athlete's heart is usually characterised by a “conditioned heart rate”. People with athlete's hearts will now show symptoms or serious warning signs and thereby won't need a specific treatment for the condition.

Common Signs Of Athlete’s Heart

Signs include:

• Slow resting heart rate (bradycardia)

• Mild enlargement of the heart on imaging

• Changes on an electrocardiogram (ECG)

• High exercise capacity with no symptoms

Athlete’s Heart Is Different From Cardiac Diseases

The expert also says that athlete's heart is different from serious cardiac diseases like cardiomyopathies, especially hypertrophic obstructive cardiomyopathy (HOCM).

He says, “HOCM is a serious disease, with heart muscle thickening also occurring and causing the left ventricular cavity to narrow. The left ventricle's outflow tract can also become obstructed from this excessive thickening. Athletes with HOCM have a risk of sudden cardiac arrest and death, unlike athletes with athlete's heart.”

An athlete‘s heart, by itself, is considered a benign physiological adaptation and does not require medical intervention.

However, it becomes important to investigate further if an athlete experiences:

• Chest pain during exercise

• Unexplained fainting

• Palpitations

• Shortness of breath out of proportion to exertion

• Reduced exercise performance

• A family history of sudden cardiac death or inherited heart disease

Ignoring these warning signs can delay the diagnosis of potentially serious cardiac conditions. Those who have an athlete’s heart must get periodic cardiac evaluation, do a temporary reduction in training if the diagnosis remains uncertain, and monitor when minor abnormalities are present.

Athlete's heart is proof of the body's extraordinary ability to adapt to sustained physical activity. For most athletes, it represents a healthy, efficient cardiovascular system rather than a medical problem. The challenge lies in distinguishing these normal adaptations from potentially dangerous heart conditions that can look remarkably similar.

Adults under 40 with obesity continue to face a higher risk of cardiovascular disease than their peers with a normal Body Mass Index (BMI), according to a new study published in The Lancet.

The international study, led by researchers at Imperial College London, found that differences in blood pressure and unhealthy cholesterol levels between older adults with obesity and those with a normal BMI have narrowed—or even disappeared—in several high-income countries over the past three decades. In contrast, little or no such improvement was seen among younger adults.

Younger Adults Show No Similar Improvement

The findings suggest that adults under 40 with obesity continue to have higher blood pressure and unhealthy cholesterol levels than those with a normal BMI.

Obesity is a key risk factor for heart disease.

Researchers also found that the use of cholesterol-lowering and blood pressure medications remains low in this age group, supporting the idea that medication has played a key role in reducing cardiovascular risk among older adults.

"While good news for older adults with obesity, our results suggest that cardiovascular health risks remain higher for adults under 40 than for their counterparts with a normal BMI,” said author Ysé d'Ailhaud de Brisis, from the School of Public Health at Imperial.

"Early lifestyle interventions, screening, and, when appropriate, medication in this younger group should be considered to prevent long-term cardiovascular complications linked to obesity," de Brisis added.

Older Adults See Reduced Risk

Since the 1990s, blood pressure and unhealthy cholesterol levels have fallen more rapidly among adults aged 40 to 79 with obesity than among those with a normal BMI in most of the seven high-income countries studied, including England and the US.

The greatest improvements were seen among adults aged 60 to 79. In England and the US older adults with obesity—particularly those with severe obesity—had similar or even lower blood pressure and unhealthy cholesterol levels than those with a normal BMI by the end of the study period.

Heart Medications May Explain the Trend

The researchers said the narrowing gap is largely due to increased use of cholesterol-lowering medications, such as statins, and blood pressure medicines among adults over 40 with obesity.

For example, by the early 2020s, around 70% to 72% of older men with severe obesity in England and the US were taking cholesterol-lowering medication, compared with 40% to 48% of older men with a normal BMI.

“This latest analysis suggests that the observed convergence in cholesterol and blood pressure levels between people aged over 40 with obesity and those with a normal BMI is largely due to statins and other widely accessible medications to reduce cardiovascular risk. That is a significant public health success story, and one we should not lose sight of as new weight-loss medications enter the picture,” said author Lakshya Jain, from the School of Public Health at Imperial.

How Was the Study Conducted?

The researchers analyzed blood pressure and cholesterol data from nearly one million participants across 110 health datasets collected between 1990 and 2024.

The study included people with obesity, overweight and normal BMI from seven high-income countries: England, the US, Japan, South Korea, Taiwan, Thailand and Finland.

The authors also acknowledged limitations of the study such as, the findings may not apply to low- and middle-income countries, where access to cholesterol- and blood pressure-lowering medications is lower. Further, the study could also not assess the impact of different medication doses because prescription data were unavailable.

Popular GLP-1 medications such as Ozempic, Wegovy, and Zepbound are well established for improving metabolic health, lowering blood sugar and promoting weight loss. These blockbuster drugs are also known to reduce the risk of conditions such as heart disease and type 2 diabetes.

Now, researchers are exploring whether these medications could also help slow biological aging and potentially increase longevity.

Study Explores Anti-Aging Potential

A recent US National Institutes of Health (NIH)-backed study, published in the journal Nature, found that Ozempic slowed biological aging in people living with HIV and lipohypertrophy, a condition in which fatty deposits develop under the skin.

People with HIV often experience accelerated aging because of the infection, making them an important group for age-related research, said lead author Dr. Michael Corley, associate professor of medicine at the University of California, San Diego's Stein Institute for Research on Aging, according to The New York Times.

Although the trial was preliminary, Dr. Corley said it "provided us an opportunity to say, hey, is there any signal here that warrants all the hype?"

Can GLP-1 Drugs Slow Aging?

Experts believe the findings are promising, but stressed that more research is needed.

Dr. Nicolas Musi, director of the Diabetes and Aging Center at Cedars-Sinai, told NYT that because these drugs reduce the risk of diseases associated with aging, they could potentially improve lifespan as well.

"GLP-1 agonists decrease the incidence of diseases that are related to aging and are associated with decreasing life span. One would assume that they're also potentially going to increase life span and be beneficial for longevity," Dr. Musi said.

Researchers also point to the drugs' anti-inflammatory effects. Chronic inflammation is one of the biological processes linked to aging, said Dr. Thomas Blackwell, professor of general internal medicine at the University of Texas Medical Branch in Galveston.

However, scientists caution that there is currently no evidence showing that GLP-1 drugs provide longevity benefits for people who are already metabolically healthy.

What Are GLP-1 Drugs?

Drugs such as Ozempic and Wegovy contain semaglutide, a GLP-1 receptor agonist, while Zepbound and Mounjaro contain tirzepatide.

These medications are approved for the treatment of type 2 diabetes, and some are also approved for chronic weight management.

GLP-1 receptor agonists work by binding to GLP-1 receptors in the body. This increases insulin production in response to food, suppresses glucagon—a hormone that raises blood sugar—and helps regulate blood glucose levels.

What Does GLP-1 Do in the Body?

GLP-1 (glucagon-like peptide-1) is a hormone naturally produced by the small intestine after eating. It plays several important roles in regulating blood sugar and appetite by:

• Stimulating insulin release from the pancreas.
• Suppressing glucagon secretion, which helps prevent unnecessary increases in blood sugar.
• Slowing stomach emptying allows glucose to enter the bloodstream more gradually.
• Increasing feelings of fullness (satiety), which helps reduce food intake.
