Cigarettes with ultralow nicotine levels are now being called the game-changer in the fight against smoking. If you are having trouble in quitting smoking, then, it is for you, that soon the Biden White House is expected to formally propose a plan that will order cigarette nicotine levels to be reduced, reports The Washington Post. For now though, it has been a failure, as these cigarettes, also known as VLN cigarettes that stands for very low nicotine are only available in 5,100 stores in 26 states. This is a very small fraction of the overall market for cigarettes. The company that makes it, 22nd Century, is struggling not because of the low supply, but also from the advocates who have long believed slashing nicotine levels altogether.

The Advent and ideation

Nicotine is a chemical that is produced naturally from tobacco that makes the cigarette and also keeps people hooked. While it is believed that it makes people alert, and get the "hit" to keep them going, it exposes the users to harmful substances, carcinogens, and increases the risk of heart disease, lung cancer, and other illness.

Ultralow-nicotine cigarettes, like the VLN brand, contain about 95% less nicotine than the regular cigarettes. The idea is quite simple: without the addictive grip of nicotine, smokers will find it easier to quit. Research too has shown some promise. For instance, the studies funded by the National Institute on Drug Abuse revealed that very low nicotine cigarettes reduced addiction potential significantly without having users to increase their smoking frequency. However, the problem is, why would anyone choose for a low-nicotine that does not make them feel the same way, when the high-nicotine cigarette is right next to it, making them feel the same way, with the same alertness, sold at the same price.

“It’s very hard to imagine someone actively choosing to continue to use a low-nicotine product for the same price when a high-nicotine product is right next to it,” said Eric Donny, a Wake Forest University School of Medicine nicotine researcher.

No wonder, the experiment with low nicotine product by Philip Morris' Next cigarettes in the 1980s and Vector Tobacco's Quest brand in the early 2000s, flopped.

FDA's Role in the Push

The Food and Drug Administration (FDA) has supported the development of such products, even allowing VLN cigarettes to be marketed as lower-risk options. However, these products remain a niche market, available in only a fraction of U.S. stores.

Recently, the Biden administration has considered a bold step—mandating a dramatic reduction in nicotine levels for all cigarettes sold in the United States. Supporters believe this move could save millions of lives, while critics, including tobacco companies, warn of potential unintended consequences.

What Could Be The Challenges?

Resistance from Big Tobacco Companies: They could argue that slashing nicotine levels could backfire. Their claim is, smokers will turn to black markets or smoke more to satisfy their cravings, which may lead to greater exposure to harmful substances.

Consumer Reluctance: History is proof to the instances of smokers being hesitant to embrace the low-nicotine products.

Political Hurdle: It may face political roadblocks, as under the Trump administration, plans to cut nicotine were shelved.

Could Low-Nicotine Cigarettes Be The Solution?

Advocates believe that ultralow-nicotine cigarettes could be a game-changer, comparing them to decaf coffee or non-alcoholic beer—products that reduce harm while offering a similar experience.

Some experts warn that a black market for traditional cigarettes could undermine these efforts. They also stress the need for safer alternatives, such as vaping products, to support smokers transitioning away from traditional cigarettes.

For the past two days, Delhi locals have been waking up to extreme heatwave conditions. The India Meteorological Department (IMD) issued a warning of an extreme heatwave for Friday and Saturday, and we are now on day 2. On Friday, temperatures in the national capital were recorded at 43.1 degrees Celsius and 41.9 degrees Celsius. At the Ridge station and Lodhi Road, a high of 41.8 degrees was recorded, which met the criteria for heatwave conditions. Citing this, the IMD issued a yellow alert for Saturday, forecasting isolated heatwave conditions in the city. With this comes an increased risk of heat stress.

What is heat stress?

Heat stress refers to a state wherein the body absorbs more heat from the environment or produces heat through exertion that overwhelms the body's natural cooling system. This is caused by humidity, high temperatures, or exercise, leading to symptoms like headaches, dizziness, and, in extreme cases, heatstroke.

Heat stress occurs when the body is exposed to radiant heat, high air temperature, physical exertion, high humidity, or low air movement. It harms the body's ability to maintain a normal core temperature, thereby resulting in dehydration and cardiovascular strain. It is advised to wear protective clothing and drink plenty of water to stay hydrated.

What are the signs of heat stress?

Dr Anirban Chattopadhyay, Senior Consultant, Critical Care Medicine, CK Birla Hospitals, CMRI, in an interaction with Health and Me, spoke about the symptoms of heat stress. The expert said, “As the summer season begins and the sunlight is now scorching, heat and related symptoms increase. One of the early symptoms of heat exhaustion is headache, light-headedness, dizziness, and brain fog. This happens because the brain is temperature-sensitive. That is why patients often experience a headache when temperatures rise. This occurs due to vasoconstriction. One may experience dizziness and brain fog because the brain cannot withstand high levels of heat. These are the early symptoms of heat stress.”

When heat stress or prolonged heat exposure continues, it can progress to a more serious condition. This may even lead to a comatose state, known as heatstroke. Therefore, avoid direct sunlight exposure. If possible, stay indoors during peak hours, from 12 pm to 3 pm. Drink plenty of water to keep yourself hydrated, and consume electrolyte-containing fluids to maintain balance. When going out, use umbrellas and sunglasses, and wear breathable fabrics like cotton.

Heatwave across Central and North India

The heatwave is not restricted to the national capital—it is currently affecting northern and central states such as Madhya Pradesh, Rajasthan, Bihar, Chhattisgarh, Chandigarh, and Haryana. The conditions are likely to continue until April 27, with low chances of relief in the coming week.

World Malaria Day is observed on April 25 every year - on this day, experts spread awareness about malaria, an infection caused by the bite of the female Anopheles mosquito. Its symptoms include extremely high fever, headaches, chills, and fatigue. However, ahead of or during the monsoon season, people often get confused between viral fever and malaria due to similar symptoms. As a result, the infection is diagnosed late. On this occasion, Health and Me interacted with experts to learn more about the tests that one must take for malaria diagnosis.

An increase in the number of patients presenting at diagnostic centres with very high fevers has been attributed to people assuming they have a seasonal virus; however, when these patients present later, they often have life-threatening complications. According to the World Health Organization, over 280 million cases of viral infections worldwide were reported last year, making the clinical distinction between malaria and viral diseases increasingly deceptive.

Which tests to take for malaria diagnosis?

Dr Divya C, Microbiologist at Neuberg Anand Reference Laboratory, said, “Diagnostic testing has also transformed from the traditional microscope to more advanced diagnostic techniques, such as dual-target RDT (rapid diagnostic test), which detects HRP2 and Pf-LDH antigens. The RDT may not be able to detect some infections with lower numbers of malaria parasites circulating in the patient’s bloodstream. Therefore, all negative RDTs must be followed by microscopy to confirm the result.”

The expert went on to say that molecular PCR tests are now the preferred tests for cases with low parasite density or asymptomatic carriers, as they can detect fewer than 10 parasites per microlitre of blood with high levels of sensitivity. Some leading laboratories that perform PCR testing are also including AI-assisted digital microscopy as a supplement to the process, reducing human fatigue and providing significantly more precise results than a manual smear could.

What happens when malaria is diagnosed late?

The risk of “waiting to see” if malaria develops after the initial temperature spike is that, unlike most other viral fevers, malaria infects human red blood cells; the consequence of waiting can be organ failure or cerebral complications within 48–72 hours after the initial symptomatic temperature spike.

It is recommended that any patient with cyclic chills, excessive sweating, or fatigue should be tested based on differential diagnosis, as India moves towards becoming malaria-free by 2027. There is a short 15-minute diagnostic window to determine whether a patient can be treated without complications or is at risk of dying from malaria if it is missed.

Dr Praveen K Bharti (Scientist G), Director, ICMR–National Institute of Research in Tribal Health (NIRTH), Jabalpur, said, “We need testing to catch malaria early, but we also need the right kind of tests. Traditional tests often miss low-density, mixed, and asymptomatic infections. These are not minor gaps. As India advances towards its malaria elimination goals by 2030, point-of-care molecular tests for malaria diagnosis that can detect low-density, hidden reservoirs of infection will prove to be the key differentiator.”

Every year on 25 April, World Malaria Day is observed to raise awareness about one of the deadliest yet preventable diseases.

According to the latest World Malaria Report 2025, there were 282 million cases of malaria in 2024, an increase of about 9 million cases (3 per cent) compared with 2023.

The estimated number of malaria deaths stood at 610,000 in 2024 compared to 598,000 in 2023.

With 37 countries reporting fewer than 1,000 cases in 2024, progress at the global level is stalling.

World Malaria Day 2026: Theme

The theme this year is "Driven to End Malaria: Now We Can. Now We Must."

According to the World Health Organization, for the first time, ending malaria seems to be a real possibility, as science is advancing faster than ever with new vaccines, treatments, malaria control tools and pioneering technologies.

That is why the theme "is a rallying cry to grasp the moment—to protect lives now and fund a malaria-free future".

The theme also builds on a strong line of focused global campaigns in recent years that resulted in 47 countries being certified malaria-free.

In the last few years, substantial progress has been made, with an estimated 2.3 billion malaria infections prevented and 14 million lives saved worldwide since 2000.

However, the WHO flagged that the gains are at risk due to multiple challenges, including

• drug resistance,
• insecticide resistance,
• diagnostic failure,
• severe reductions in funds.

The theme also underscores the need to end Malaria by 2030 with coordinated global action. As stronger community health systems have brought the world closer to this goal than ever before, the day presents the need to boost

• Advances in malaria vaccines,
• Improving diagnostic tools,
• Develop more effective treatments.

World Malaria Day: History

World Malaria Day was first celebrated internationally in 2008, building upon the earlier "Africa Malaria Day", which had been observed by African countries since 2001. The date, April 25, was established by the WHO in 2007 during the World Health Assembly.

In 2007, it was the 60th session of the World Health Assembly where the proposal to rename Africa Malaria Day to World Malaria Day was made to acknowledge the global presence of malaria.

World Malaria Day: Significance

The day has a strong significance in healthcare as it brings attention to the disease that still continues to take so many lives, especially in low-income and tropical regions. It also serves as an important reminder to continue spreading awareness about the disease as well as promoting its prevention, treatment, and continuous international cooperation to fight against it.

What Is Malaria?

The WHO describes malaria as a life-threatening disease spread to humans by some types of mosquitoes, mostly found in tropical countries. However, they are preventable and curable.

"Malaria is spread to people through the bites of some infected anopheles mosquitoes. Blood transfusion and contaminated needles may also transmit malaria," as per the WHO.

The first symptoms may be mild, similar to many febrile illnesses, and difficult to recognize as malaria. Left untreated, P. falciparum malaria can progress to severe illness and death within 24 hours.

The WHO notes 5 Plasmodium parasite species that cause malaria in humans.

• P. falciparum — the deadliest malaria parasite and the most prevalent on the African continent.
• P. vivax — the dominant malaria parasite in most countries outside of sub-Saharan Africa.

• P. malariae,
• P. ovale
• P. knowlesi.

Symptoms of Malaria

The early symptoms include fever, headache, and chills, which can usually start within 10 to 15 days of getting bitten by an infected mosquito.

Some types of malaria can cause severe illness and death. Infants, children under 5 years, pregnant women, travellers, and people with HIV or AIDS are at higher risk. Severe symptoms include:

• extreme tiredness and fatigue
• impaired consciousness
• multiple convulsions
• difficulty breathing
• dark or bloody urine
• jaundice (yellowing of the eyes and skin)
• abnormal bleeding.
