Scientists blame climate change for the rise in alcohol and drug use.
A team from Columbia University analyzed hospital rates in New York state from 1995 to 2014 and found an increase amid warmer temperatures.
The researchers suggested that alcohol-related visits may be driven by people’s tendency to consume more substances in pleasant outdoor weather and to sweat more, leading to dehydration.
For other drug use, such as cannabis, cocaine, opioids, and sedatives, higher temperatures also led to more hospital visits, but only up to a threshold of 65.8°F.

The study authors note that their study may underestimate the link between temperature rise and substance use because more severe disorders may have led to deaths before a hospital visit was possible.
First author Robbie M. Parks said: “We saw that during periods of higher temperatures, there was a corresponding increase in hospital visits related to alcohol and substance use, which also draws attention to some potential consequences less obvious consequences of climate change.
The team used data. of 671,625 hospital visits for alcohol- and 721,469 substance-related disorders over 20 years, compared to record daily temperatures and relative humidity.
This allowed them to create a statistical model of days with high temperatures and nearby days with lower temperatures to understand the impact of short-term climate-related phenomena, such as periods of high heat.

For other drug use, including cannabis, cocaine, opioids, and sedatives, higher temperatures also led to more hospital visits, but only up to a threshold of 65.8°F.

The data showed that hospital visits for alcohol-related disorders increased by 24 percent amid higher temperatures, while drug-related visits saw an increase of up to 42 percent.
The researchers found that the higher the temperatures, the more hospital visits for alcohol-related disorders.

“Men accounted for the majority of hospital visits for all causes, ranging from 53 percent for sedatives to 63 percent for alcohol-related disorders,” the study reads.
The majority of hospital visits were inpatients, ranging from 68 percent of hospital visits for cannabis to 87 percent of hospital visits for sedatives. The majority of hospital visits also did not occur in New York City, ranging from 53 percent of hospital visits for cocaine and opioids to 67 percent for cannabis.
Lead author Marianthi-Anna Kioumourtzoglou said: “Public health interventions that broadly target alcohol and substance disorders in warmer climates (for example, specific messages about the risks of their use during warmer climates) should be a public health priority.
The National Institutes of Health (NIH) shared data from 2022 showing that the highest alcohol-related hospital admissions were recorded in July, August and May.
In the United States, many Americans begin summer in May, which would explain an increase in hospital visits.
Doctors blame climate change for health problems, with one Canadian medical professional pointing to it as the cause of a patient’s asthma.
This was determined after an unprecedented heat wave and poor air quality contributed to the person’s deteriorating health.
Dr. Kyle Merritt, who works at a hospital in Nelson, British Columbia, said environmental hazards led him to make his first clinical diagnosis of “climate change” after treating a patient who was struggling to breathe.
“If we don’t look at the underlying cause and just treat the symptoms, we will continue to fall further and further behind,” the emergency room doctor told Glacier Media.
“It’s me trying to just…process what I’m seeing.”
And in July, another Canadian think tank said climate change is accelerating the rate of blindness.
Researchers at the University of Toronto compared rates of vision problems among 1.7 million people in all 50 U.S. states.
They found that those who lived in warmer regions were up to almost 50 percent more likely to suffer from severe visual impairment than those who lived in colder places.
