Researchers found PPM abuse varies greatly across US states, differing from traditional illicit drug trends. States with large metropolitan areas often have lower abuse rates despite perceptions of city dwellers being more prone to drug use.
Research at Brookhaven National Laboratory found that cocaine-addicted individuals have a flattened sensitivity to relative monetary rewards, making it harder to inhibit maladaptive behavior. This altered perception of reward is linked to changes in the prefrontal cortex, a brain region essential for monitoring and controlling behavior.
A study of 14 adults with histories of sedative abuse found that the new sleep medication ramelteon does not appear to have effects indicating potential for abuse or motor or cognitive impairment. Ramelteon works through a different pathway in the brain and may be less likely to cause such effects.

By improving the emotional quality of mother-child relationships, the program aims to promote children's psychosocial development and reduce preoccupation with drug use.
The American Academy of Pain Medicine calls for a balance between treating legitimate pain and preventing misuse, with healthcare professionals at the forefront. Government initiatives have shifted regulatory authority from health agencies to law enforcement, leading to tension and imbalance in pain care.
A study found that prescription monitoring programs can reduce problematic use of benzodiazepines but also decrease access to appropriate treatment for patients with chronic illnesses. Racial disparities in access to effective care were exacerbated by these policies, highlighting the need for re-examining health policy impacts.
A five-year study found that recovery coaches improved reunification outcomes for a small but significant number of families, with 15.5% of those with coaches being reunited compared to 11.6% in the control group. The intervention also saved $5.6 million over five years by reducing foster care time and costs.
A study examining drug use surveys found significant differences in how willing respondents were to disclose their use, particularly for marijuana and cocaine. The researchers suggest supplementing major surveys with drug tests to estimate willingness-to-disclose and its variation across different drugs and demographic characteristics.
A study compared the abuse potential of two methylphenidate formulations, finding that the delayed-release version took longer to produce maximum effects and was less detectable. Researchers suggest that different formulations may vary in safety characteristics, warranting further study.

The research found that participation in 12-step fellowship programs and social support networks significantly enhances recovery outcomes.
A recent study published by the University of South Florida has found that drug use is linked to an increased risk of brain hemorrhage in young adults. The study analyzed data from 307 patients with intracerebral hemorrhage and found that cocaine, marijuana, and amphetamines were common substances of abuse among those under 50.
Liver injuries continue to plague the nation's drug development system, causing costly problems for pharmaceutical companies. Dr. Navarro proposes that patients speak with their physicians about their medications to detect liver injury early, as certain individuals are more likely to develop problems due to genetic makeup.
Orexin strengthens neural communication between dopamine-releasing neurons, playing a key role in drug high experience and craving. Blocking orexin action reverses cocaine-craving behavior in rats.
