Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.

Fog that Feeds Fear

The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.

Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."

Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.

2. Why the Chemical Smell?

Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

3. What are the Health Concerns?

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.

Psychological Effects of Mass Panic Caused by Social Media

Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.

According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.

The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.

Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.

On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.

The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.

The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.

In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

India's Supreme Court has revamped guidelines for intensive care units (ICUs) across the country, and the top court has also asked all the states and Union Territories to prepare a “realistic and practical” action plan to implement the guidelines necessary as a minimum standard for intensive care units.

As per the new draft guidelines, set to be implemented from mid-May, patients who are stable and no longer need critical support will be shifted out of ICUs to wards or other care units.

The guidelines, prepared by a three-member court-appointed committee and reviewed by leading medical experts, were endorsed by the apex court as “practical, implementable, and necessary as a minimum standard for an ICU,” The Hindustan Times reported.

A bench of Justices Ahsanuddin Amanullah and R Mahadevan said copies of the guidelines should be shared with all the states and UTs.

“Moving further, as an immediate measure, let all the additional chief secretaries/secretaries … heading the department of health and medical education in the states and the UTs, convene a meeting of all experts involved in this exercise to prepare an action plan for implementation of the guidelines. Such a plan shall be realistic and practical,” the bench said in its order.

What Are The Draft Guidelines?

• The guidelines prepared by experts, including AIIMS doctor Nitish Naik, Additional Solicitor General Aishwarya Bhati, and advocate Karan Bharioke as amicus curiae, stressed that doctors’ clinical judgment should guide decisions on the level of care for each patient.

• The guidelines set minimum standards for how ICUs should function. They recommend having one nurse for every two to three patients in basic ICUs, and one nurse per patient in advanced ICUs where patients need multiple organ support, The Times of India reported.

They also call for round-the-clock monitoring by resident doctors working in shifts, under the supervision of specialists with postgraduate qualifications recognized by the National Medical Council.

• The document lists requirements for equipment such as ventilators, oxygen supply systems, patient transport facilities, and bedside utilities. It also lays down norms for infection control, fire safety, record-keeping, and regular audits, the media reports said.

• For capacity, the guidelines suggest that a basic ICU should have six to eight beds, which can be expanded to about 12 beds in hospitals handling more critical cases, depending on the services offered.

The SC bench had urged for a meeting of all concerned to discuss and prepare a final common guideline, which shall then be circulated to all states and UTs.

“A final report/blueprint/recommendation shall be prepared, which shall be placed before this court on the next date,” it said, adding that the entire exercise should be completed within three weeks.

“Let the Ministry of Health, Government of India, formally issue the guidelines placed before us today, to the states and UTs concerned by way of an advisory. A copy of it shall also be uploaded on the website of the Ministry of Health, Government of India,” the bench said, while posting the matter for further hearing on May 18.

Amid the continuously rising temperatures in India’s national capital, the Delhi government has launched several measures, from cool roofing to misting systems at bus stops, to ORS support for schoolchildren, and rest periods for construction workers, to beat the heat.

Delhi Chief Minister, Rekha Gupta, who reviewed the Heat Wave Action Plan 2026 and directed officials to ensure its strict implementation, noted that the action plan this year is more scientific and robust than in previous years.

The action plan comes as the India Meteorological Department (IMD) shows no respite from heat for Delhi.

The agency has issued a yellow alert for today, with heatwave conditions likely at isolated places and maximum temperatures expected to reach 43-45°C. On Sunday, the city recorded a maximum temperature of 42 degrees Celsius, 3.1 degrees above the seasonal average.

However, very light rain is likely towards the afternoon. Partly cloudy skies and very light rain are forecast for Tuesday and Wednesday, which is expected to bring a slight drop in maximum temperatures.

Heatwave Action Plan 2026

• According to a statement issued by the CMO, the government is laying a special focus on school children and supplying ORS to them.

Schools are likely to administer an ORS solution before children leave school, if required, to reduce the risk of dehydration during their commute.

• For construction workers, strict measures will be enforced during peak heat hours. Outdoor work may be halted between 12 noon and 3 p.m. during severe heatwave conditions.

Workers will also be provided with drinking water, caps, and Gamchas coverings for protection against the sun. First-aid kits and ice packs will be made available at worksites when needed.

• The government also launched a ‘Cool Roof Policy 2026’. As part of it, reflective coating has already been applied over nearly 28,674 sq ft at the Kashmere Gate ISBT, helping reduce indoor temperatures.

High-pressure misting systems will be installed at bus stops, while anti-smog guns will be used to cool densely built-up areas.

• Further, the Heatwave Action Plan 2026 has been carried out a detailed scientific assessment of the entire city using satellite data to identify high-risk zones. The action plan will focus on “thermal hotspots”, areas that in 2025 recorded severely high temperatures. This includes

1. Ayanagar (45.5°C)
2. Najafgarh (43.7°C in 2025)
3. Safdarjung (46.8°C in 2023)

1. Sawda,
2. Mubarakpur Dabas,
3. Bhalswa,
4. Nand Nagri,
5. Gokulpuri
6. Bakkarwala.

• Departments such as the DDA, the Education Department, and the Delhi Jal Board have been asked to ensure water and shade not just for people but also for animals and birds.

• Cool rooms in Hospital

In addition, 39 Quick Response Teams and trained ASHA workers are on standby. Arrangements for cold drinking water and ORS will be made at busy public locations, including bus stops and terminals.

• The Chief Minister has also asked to implement a special priority protocol to ensure an uninterrupted 24x7 power supply to critical facilities such as hospitals, Water Treatment Plants (WTPs), and mobile towers.

While psychedelics—psychoactive substances known to alter perception and mood—have long been sidelined, the US President Donald Trump and his administration are bringing them back to mainstream treatment.

In a significant push, Trump last week signed an executive order where he directed the Food and Drug Administration (FDA) to expedite a review of psychedelic drugs, including ibogaine.

The executive order signed on Saturday is designed to fast-track both research on and access to these drugs. It also includes a $50 million investment in state governments to study how psychedelics might help people struggling with mental health illnesses.

Emerging research shows psychedelics can help improve mental health, especially in conditions where traditional treatment approaches have not been useful. However, these drugs also come with several health risks that cannot be overlooked.

According to FDA Commissioner Dr. Marty Makary, ibogaine could “soon” be on track to receive FDA approval once the agency reviews data from late-stage clinical trials, CNN reported.

“Once we have them in-house, we’ll be issuing National Priority Vouchers for a review within one to two months instead of the standard one-year time frame. And that’s because this is a national priority,” Makary said.

“These are potentially promising treatments,” he said. “We’ll see how the data reads out when we get the applications, but we don’t want to waste any time, because this is an urgent matter given the mental health crisis,” the Commissioner said.

Makary noted that if ibogaine gets approved, these will be "given in a controlled, supervised setting in a hospital.”

What Is Ibogaine?

Historical evidence suggests that ibogaine was first used by the Pygmy people in Central Africa as a sacred medium, believed to be a gift from God, which allowed them to reconnect with the divine and the dead.

It was later, during the colonial period, that the communities in the region used the compound for unity and shared experience.

It was in 1962 that Ibogaine was first seen as a potential treatment for substance-related disorders by researchers in the US. While studies back then showed promising results, psychedelics were considered controversial and, broadly, “abandoned” by researchers.

Since 1967, the Drug Enforcement Administration (DEA) in the US has classified ibogaine as a Schedule I controlled drug. Schedule I substances are those that currently have no accepted medical use and have a high potential for abuse. They are also illegal to use.

However, in recent years, ibogaine has garnered several high-profile supporters, including former Texas Gov. Rick Perry, former Sen. Kyrsten Sinema of Arizona, and podcast host Joe Rogan.

Is Ibogaine Beneficial? What Are The Health Risks?

As per preliminary research, ibogaine has the potential to alter certain brain pathways, which can improve some mental health conditions, including PTSD, anxiety, or depression.

The executive order is a “great step,” Dr. Kirsten Cherian, a researcher at Stanford University who led a landmark study on ibogaine, was quoted as saying to CNN. Cherian added that the order may open the door to offering the treatment in US research facilities.

“The first step is to be able to do the research at home,” she said. “And it could open up a lot of research possibilities. It is kind of an exciting time.”

As per the Legislative Analysis and Public Policy Association, Ibogaine’s effects are prolonged, beginning a half hour to three hours after ingestion and can last more than 24 hours.

Individuals who have used ibogaine report experiencing a dream-like state with visual and sensory distortions. After the peak effects of the substance abate, users report going through a period of reflection and report having residual effects lasting up to 72 hours that include heightened awareness, mild stimulation, and disturbed sleep.

The hallucinogen is also known to raise the risk of abnormal heart rhythms, which could cause vomiting. This makes the use of the substance particularly risky for individuals with preexisting heart problems. There has been a total of 33 ibogainerelated deaths publicly reported in scientific literature to date.
