(Press-News.org) In recent years, there has been an increase in emergence and use of a variety of new drugs, so-called "novel psychoactive substances" (NPS) in the US and worldwide. However, there is little published survey data estimating the prevalence of use in the US. Media reports about use of new drugs such as "Spice" ("synthetic marijuana") and "bath salts" such as "Flakka" are now common, yet very few health surveys ask about use of such drugs.
A new study, published in Drug and Alcohol Dependence by researchers affiliated with New York University's Center for Drug Use and HIV Research (CDUHR), examined self-reported use of 57 different new drugs and found that prevalence of use increased from 2009 to 2013. Use of these new drugs was most common among males, whites, older individuals, those of lower income, and among those residing in cities. Use of various other illicit drugs such as LSD, cocaine, and ecstasy/MDMA (a.k.a.: "Molly") was very common among users.
"About 1% of subjects self-reported any use of the 57 new drugs we examined," said Joseph J. Palamar, PhD, MPH, a CDUHR affiliated researcher and an assistant professor of Population Health at NYU Langone Medical Center (NYULMC). "Use of psychedelic tryptamines--primarily DMT--was most common, followed by psychedelic phenethylamines and synthetic cannabinoids."
The article, "Self-Reported Use of Novel Psychoactive Substances in a US Nationally Representative Survey: Prevalence, Correlates, and a Call for New Survey Methods to Prevent Underreporting," used data on self-reported use of new drugs from the National Survey of Drug Use and Health (NSDUH) (2009-2013), a national representative sample of non-institutionalized individuals in the US. Subjects were asked to provide names of (non-traditional) drugs they used that they were not specifically asked about. The researchers examined lifetime prevalence and sociodemographic correlates of self-reported use of new and uncommon synthetic drugs among subjects ages 12-34-years-old (N=213,076).
The researchers found that almost all (?95%) subjects who reported use of a new drug also reported lifetime use of alcohol, marijuana, or cigarettes, and lifetime use of ecstasy (79.4%), opioids (79.1%), cocaine (74.3%), and LSD (73.7%) were also common.
"This is the first study reporting on use of a variety of new drugs in a nationally representative US sample," said Dr. Palamar. "However, we're pretty confident that use of new drugs was severely underreported, as the research subjects were not asked about most of these drugs specifically."
Dr Palmar also points to prior research and analyses of other national data which suggest much higher rates of use of 'bath salts' and 'synthetic marijuana' than this data showed.
"Hundreds of new psychoactive drugs have come out in recent years and some of them can be very dangerous," Dr. Palamar cautions. "We need health surveys to ask about use of new drugs, in addition to traditional drugs such as marijuana and cocaine, in order to quickly pick up on potential drug epidemics."

Montreal, September 15, 2015 -- With the federal election around the corner, child care has become a major ballot issue. While every party has its own idea of how best to offset the costs of raising children, no one is looking at how we perceive and value those who provide the education and care.
Concordia researcher Sandra Chang-Kredl wants that to change. In a paper recently published in the Journal of Media & Cultural Studies, she writes that "invariably, the focus of the debate is on the children's needs, the parents' needs and society's needs. The educator is rarely ...
DURHAM, N.C. -- Energy companies used nearly 250 billion gallons of water to extract unconventional shale gas and oil from hydraulically fractured wells in the United States between 2005 and 2014, a new Duke University study finds.
During the same period, the fracked wells generated about 210 billion gallons of wastewater.
Large though those numbers seem, the study calculates that the water used in fracking makes up less than 1 percent of total industrial water use nationwide.
While fracking an unconventional shale gas or oil well takes much more water than drilling ...
In what is believed to be the largest, most detailed study of its kind in the United States, scientists at NYU Langone Medical Center and elsewhere have confirmed that tiny chemical particles in the air we breathe are linked to an overall increase in risk of death.
The researchers say this kind of air pollution involves particles so small they are invisible to the human eye (at less than one ten-thousandth of an inch in diameter, or no more than 2.5 micrometers across).
In a report on the findings, published in the journal Environmental Health Perspectives online Sept. ...
Fetuses with enlarged ventricles--the fluid-filled cavities inside the brain--may be less likely than other fetuses to benefit from surgery in the womb to treat spina bifida, according to a study co-authored by researchers at UCSF Benioff Children's Hospital San Francisco.
The researchers found that fetuses with enlarged ventricles were more likely to require a second surgery to relieve a life-threatening build-up of pressure within the brain. Given the risks that fetal surgery poses for mother and newborn, the findings indicate that in these cases, it may be better ...
Sydney, Australia -- Creating futuristic, next generation materials called 'metallic glass' that are ultra-strong and ultra-flexible will become easier and cheaper, based on UNSW Australia research that can predict for the first time which combinations of metals will best form these useful materials.
Just like something from science fiction - think of the Liquid-Metal Man robot assassin (T-1000) in the Terminator films - these materials behave more like glass or plastic than metal.
While still being metals, they become as malleable as chewing gum when heated and can ...
BERKELEY -- A new study by University of California, Berkeley, researchers establishes for the first time a link between infection with the bovine leukemia virus and human breast cancer.
In the study, published this month in the journal PLOS ONE and available online, researchers analyzed breast tissue from 239 women, comparing samples from women who had breast cancer with women who had no history of the disease for the presence of bovine leukemia virus (BLV). They found that 59 percent of breast cancer samples had evidence of exposure to BLV, as determined by the presence ...
Planning conservation actions requires up-to-date information on
Biodiversity is diminishing at unprecedented rates, and quick decisions are needed in what and where to protect.
"The decisions should be based on comprehensive information, but scientists do not have enough resources to collect more data and effectively monitor all species and habitats that need protection. As human are the main driving force of global change, conservation also needs information on human presence and behaviour" says Enrico Di Minin, a researcher in conservation science at the Department ...
A new study has found increasing support in the United States and Canada for smokefree laws for outdoor areas, especially in playgrounds and school grounds.
The collaborative study between the University of Otago, New Zealand and University of Alberta, Canada, provides new and some unexpected insights for health promotion in North America. A key finding is that most residents welcome smokefree laws. Support was strongest for smokefree playgrounds and school grounds, but there was also majority support for a range of other smokefree areas.

Highly diluted acetic acid, an active ingredient of household vinegar, has been shown to be an effective alternative agent to prevent infection and kill bacteria found in burn wounds.
Researchers from the University of Birmingham and the National Institute for Health Research (NIHR) Surgical Reconstruction and Microbiology Research Centre (SRMRC) investigated the antibacterial activity of acetic acid against key burn wound colonising organisms growing both planktonically and as biofilms.
Burns are a common traumatic injury and prone to becoming infected due to loss ...
On Sept. 13, 2015, as NASA's Solar Dynamics Observatory, or SDO, kept up its constant watch on the sun, its view was photobombed not once, but twice. Just as the moon came into SDO's field of view on a path to cross the sun, Earth entered the picture, blocking SDO's view completely. When SDO's view of the sun emerged from Earth's shadow, the moon was just completing its journey across the sun's face.
Though SDO sees dozens of Earth eclipses and several lunar transits each year, this is the first time ever that the two have coincided. This alignment of the sun, moon and ...
