The United States in the grip of several simultaneously occurring opioid epidemics, rather than just a single crisis. The epidemics came to light after the researchers analyzed county-level data on drug overdose deaths. The study highlights the importance of different policy responses to the epidemics rather than a single set of policies.
New findings reveal the prevalence of cannabis, or marijuana, use in the United States increased from 2005 to 2017 among persons with and without depression and was approximately twice as common among those with depression in 2017.
The composition of suspicious powders that may contain illicit drugs can be analyzed using a quick and simple method called magneto-Archimedes levitation (MagLev), according to a new study. A team of scientists has developed the MagLev method to differentiate common street drugs in dilute mixtures. The method could complement or even replace other portable drug identification techniques, the scientists suggest.
A new study found that methamphetamine use was associated with more than twice the risk for dropping out of treatment for opioid-use disorder.
Young adults who seek enrollment in state medical marijuana programs are often those who already use heavily rather than those with mental or physical issues that could be addressed by the drug.
Daily marijuana use during pregnancy may lead to an increased risk of low birth weight, low resistance to infection, decreased oxygen levels and other negative fetal health outcomes, according to a new study.
A new study found there were more than 67,300 calls to US Poison Control Centers regarding exposures to natural psychoactive substances. The study looked at calls from January 2000 through December 2017, which totaled an average of 3,743 exposures each year, or approximately 10 calls every day.
Portland State University Chemistry Professor Rob Strongin led a research team to study what happens when additives are put into vaping products. Specifically, they studied the chemical reaction that takes place when cannabis is consumed using a vape pen or dab rig. 'What's inhaled is actually different than what's listed in the ingredients,' Strongin said.
Inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%, according to a recent study. The study also found no evidence that cannabis caused 'overuse headache,' a pitfall of more conventional treatments. The researchers did see patients using larger doses of cannabis over time, indicating they may be developing tolerance to the drug.
Researchers are investigating whether an anti-itch medication that targets a specific part of our nerve cells can make morphine -- which targets a different part--more effective. The findings suggest it can.
For those using illicit opioids to manage their chronic pain, cannabis may be a beneficial -- and a less dangerous -- alternative, according to new research.
Problematic use of marijuana among adolescents and adults increased after legalization of recreational marijuana use, according to a new study from NYU Grossman School of Medicine and Columbia University Mailman School of Public Health.
People exposed to a lifetime of psychosocial adversity may have an impaired ability to produce the dopamine levels needed for coping with acutely stressful situations.
A team has examined the effects of kratom and the potential impacts on people with alcohol use disorder.
A new analysis of US data finds an unexpectedly high prevalence of prescription opioid use among youth. As recently as 2015-2016, 21% of adolescents and 32% of young adults said they had used these drugs in the past year. Nearly 4 percent and 8 percent, respectively, reported misusing opioids.
A small study concludes that caution is warranted for users of 'high CBD, low THC' cannabis products.
The prevalence of cannabis use disorder decreased in 2002 to 2016 among frequent users. Changes in social attitudes and the traits of frequent users may explain the decline, according to researchers. This is one of the first studies to examine the general health profile of people using cannabis daily or almost daily and the trends in the prevalence of cannabis use disorder in this population.
Researchers have investigated the actions of the drug in rats. Using dopamine cell recordings, electrochemical monitoring and computer modeling, they discovered a type of feedback loop that modulates dopamine levels in the rats' brains in response to the drug. This regulatory process may shed light on methylphenidate's therapeutic properties in ADHD.
Construction workers are more likely to use drugs than workers in other professions, finds a new study.
Opioid overdose deaths in Connecticut doubled in the past 6 years, largely driven by use of multiple drugs together, according to a team of researchers.
