By analyzing more than 10,000 drug transactions, researchers have found the average joint contains 0.32 grams of marijuana, key data for policymaking.
What is the current landscape at the US federal level regarding cannabis legalization? A new report shows that from a public health perspective, the biggest concern -- the increase in youth consumption -- has apparently remained stable. From a financial perspective, it seems that it has been a success as well.
Medical marijuana is having a positive impact on the bottom line of Medicare's prescription drug benefit program in states that have legalized its use for medicinal purposes, according to new research.The savings, due to lower prescription drug use, were estimated to be $165.2 million in 2013, a year when 17 states and the District of Columbia had implemented medical marijuana laws.
Most people would get a little 'rush' out of the idea that they're about to win some money. In fact, if you could look into their brain at that very moment, you'd see activity in the part of the brain that responds to rewards. But for marijuana users, that rush just isn't as big -- and gets smaller over time, a new study finds. And that may open them up to more risk of addiction.
People who mix tobacco with cannabis are less motivated to seek help to quit.
Scientists have found preliminary evidence that tetrahydrocannabinol (THC) and other compounds found in marijuana can promote the cellular removal of amyloid beta, a toxic protein associated with Alzheimer's disease.
Girls who were overweight as children are likely to begin using cigarettes, marijuana or alcohol at an earlier age than their healthy-weight peers, according to a new study.
Marijuana often is used to self treat chronic pain and, with 24 states legalizing medical use of the herb, experts have published guidance for physicians caring for patients who use cannabis. The paper also identified opportunities for future research required to better understand the health effects of cannabinoids.
Nonmedical use of prescription opioids more than doubled among adults in the United States from 2001-2002 to 2012-2013, based on a new American study.
Adults who have drug or alcohol dependency have experienced very high rates of early adversities, according to a new study. One in five drug dependent Canadian adults and one in six alcohol dependent adults were survivors of childhood sexual abuse. This compares to one in 19 in the general Canadian population. More than one half of substance abusers had been physically abused in childhood compared to one-quarter of those who were not addicted.
Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study. Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.
A professor has developed a tool that leverages social media data to help analyze use patterns of illegal drugs by young adults across the country.
People who are addicted to cocaine are particularly prone to developing habits that render their behavior resistant to change, regardless of the potentially devastating consequences, suggests new researche. The findings may have important implications for the treatment of cocaine addiction as they help explain why such individuals take drugs even when they are aware of the negative consequences, and why they find their behavior so difficult to change.
Adolescents who use both marijuana and alcohol during middle school and high school are more likely to have poor academic performance and mental health during high school, according to a new study that followed a group of students over a seven-year period. However, the study found marijuana use was predictive of poorer functioning across more areas, including lower academic functioning, being less prepared for school, more delinquent behavior and poorer mental health.
A new study compared self-reported ecstasy/MDMA use with and without 'Molly' in the definition. Researchers found that reported lifetime use (8.0 percent vs. 5.5 percent) was significantly higher with Molly in the definition.
Addiction may be viewed as a disorder of reward learning. To date, addiction research has focused on the molecular adaptations through which memories of exposure to abused substances are encoded and maintained by nerve cells. However, glia, the non-neuronal supporting cells of the brain, have now been implicated in the consolidation of cocaine-related memories.
Latest research from a national sample of almost 10,000 US adolescents found psychological trauma, especially abuse and domestic violence before age 11, can increase the likelihood of experimentation with drugs in adolescence, independent of a history of mental illness. This is the first study to document these associations in an American national sample of adolescents.
Researchers have demonstrated that long-term marijuana users had more activity in the brain's reward processes when presented with cannabis cues than with natural reward cues.
Rice anyone? How about a bowl of ramen noodles? Researchers have found that some Asian-Americans are more likely to hunger for carbohydrates and unhealthy foods than other Asian-Americans — and the reason appears to be genetic.
Research has already shown that taking anabolic steroids is associated with high blood pressure and an increased risk of developing heart conditions such as left ventricular hypertrophy. Now research has shown that for some people misusing steroids can be particularly dangerous.
