Scientists have developed a new painkiller, which has the same morphine effect when given at a hundred times lower dose. The new drug is still under trial. According to a study published Saturday in the US Science Translational Medicine journal, the AT121 compound does not cause the same side effects caused by other harsh painkillers.

Mei-Chuan Ko, professor at the Wake Forest Baptist Medical Center, said: “In our study, we found AT-121 to be safe and non-addictive, as well as an effective pain medication. In addition, this compound also was effective at blocking abuse potential of prescription opioids, much like buprenorphine does for heroin, so we hope it could be used to treat pain and opioid abuse."

According to the US Department of Health and Human Services, more than 115 people die from opium overdoses each year in the United States.

Over 21-29 percent of patients with medical prescriptions including opium compounds used to relieve chronic pain have suffered from subsequent addiction. As of July 2017, opium addiction cases increased by 30 percent in 42 US states.

The currently marketed opium drugs focus on the so-called opioid receptors, a part of the brain that works to help people not to feel pain. Researchers have been working on developing a drug that can stimulate this part of the brain to avoid the side effects of opium, mainly addiction, shortness of breath, and increased sensitivity to pain later.

A firefighting volunteer died from severe burns, while several people were hospitalized as dozens of wildfires fueled by strong winds and scorching heat continued to rage across Spain on Wednesday.
At least six large wildfires were still out of control on Wednesday, according to regional emergency services.
The victim, a 35-year old volunteer, had been attempting to create firebreaks near the town of Nogarejas, in the north-central Castile and Leon region, when he became trapped in the blaze, regional officials said.
The fire had two active fronts that were still out of control, as weather services forecast another day of strong winds and electric storms.
Over 5,000 people have been evacuated in the region, which is Spain's largest, and efforts were being concentrated on preventing the flames from reaching smaller towns.
Environment Minister Sara Aagesen told SER radio station that many fires across the country were suspected to be intentionally caused by arsonists due to their "virulence", but that it was too early to quantify these.
On Monday, another fire had killed a man working at a horse stable on the outskirts of the Spanish capital Madrid and reached some houses and farms before it was contained.
Northwestern Galicia's regional leader Alfonso Rueda said the situation there was "complicated" and that the weather "isn't helping", as six active fires affected a combined 10,000 hectares in Ourense province.
Weather agency AEMET forecast "extreme" risk of wildfires across Spain on Wednesday.
