Long-term administration of antipsychotic drugs can worsen schizophrenia outcomes if patients consume substances like nicotine and alcohol or drugs like cannabis and amphetamines. However, measures such as administering long-acting injectable antipsychotics and psychoeducation can improve adherence and reduce substance abuse.

The study provides an important first step in investigating the effects of long-term cannabis use.
A study found that adolescents with an increasing pattern of marijuana use over their teens had the greatest dysfunction in brain reward circuitry, highest rates of depression, and lowest educational achievements. The findings highlight the importance of understanding marijuana use across adolescence to predict long-term impacts.

The study suggests that emerging symptoms of depression are a key factor in this relationship, and highlights the need for targeted prevention programs to delay or prevent marijuana use amo...
Most reproductive-age and pregnant women who use opioids for non-medical purposes also use at least one other substance, including nicotine, alcohol, or cocaine. This finding suggests that public health efforts addressing the opioid epidemic should include interventions targeting concurrent use of multiple substances among these women.
A Dartmouth study found that adolescents in medical marijuana states with many dispensaries are more likely to try new methods of cannabis use, such as edibles and vaping, at a younger age. The researchers used online surveys distributed through Facebook to collect geographically diverse data on cannabis-related questions.
The guidelines, endorsed by Canadian medical and public health organizations, offer concrete recommendations to mitigate the risks of cannabis use. They address key areas such as abstaining from cannabis, mitigating risks for young Canadians, and harm reduction strategies.
A new study found that adult marijuana use rose significantly in states with loosely regulated medical marijuana laws, particularly among adults over 26. The prevalence of cannabis use disorder remained largely unchanged. Further investigation is needed to understand the impact of regulation on marijuana use.

Teens who used cannabis regularly were 37 times more likely to be nicotine dependent and three times more likely to have a harmful drinking pattern by age 21.
A study by researchers at the University of Illinois Chicago found that low levels of tetrahydrocannabinol (THC) reduce stress, while slightly higher doses cause increased anxiety. The study used a dose-dependent approach to investigate the effects of THC on stress in healthy volunteers.
The Canadian Institutes of Health Research has invested over $1.8 million in brain health research at Baycrest, led by Dr. Tomáš Paus and Dr. Bradley Buchsbaum. The studies aim to understand how cannabis use affects brain development and memory in young adults, as well as develop targeted treatments for neurodegenerative diseases.
A study by the University of Washington's Social Development Research Group found that adult marijuana use declines with parenthood, but doesn't end. The research, published in Prevention Science, surveyed 808 adults over a 12-year period and found that parents' marijuana use is strongly related to their children's use.
The Canadian Medical Association Journal argues that marijuana legalization will jeopardize young people's health due to its toxic effects on brain development. The journal calls for restrictions on potency and quantity to minimize risk, citing evidence that the human brain continues to mature until age 25.
A special issue of Epilepsy & Behavior evaluates the benefits of medical marijuana for treating epilepsy, highlighting gaps in knowledge and education. Key findings include anecdotal data on cannabis use for epilepsy treatment and potential effects on brain function.

The study also discovered that frying food and cleaning products increase fine particle levels, posing a risk to children's health.
Researchers found that nearly one-third of older adults prescribed opiates while hospitalized experienced poor outcomes, including being restrained and requiring bladder catheterization. Alternative pain management options like acupuncture and tai chi should be integrated into inpatient care, according to the study's findings.
A new study by RTI International found that using new marijuana products and edibles significantly increases the risk of experiencing an unexpected high. Most people who experience unexpected highs sleep it off or engage in protective behaviors, but some report unintended consequences such as having sex or ending up in hospital.

Colorado hospital ER visits for teen marijuana-related issues increased fourfold after legalization, with 66% of patients exhibiting mental illness symptoms and 65% requiring psychiatric consultations. The study suggests targeted education and prevention strategies are needed to address the public health impact on adolescent populations.
A nearly three-year study in Denver found that legal marijuana shops are associated with an increase of about 84 more property crimes per year in adjacent areas. However, violent crime remained unchanged, suggesting that the negative effects of marijuana outlets may be limited to non-violent offenses.
Research finds that medical marijuana laws are associated with higher rates of illicit cannabis use and disorders, particularly in states with earlier laws. The study analyzed data from three national surveys and found significant increases in cannabis use and disorders between 1991-1992 and 2012-2013.
