05/29/14 | A New Method of Cannabis Ingestion: The Dangers of Dabs?

Because of the popularity of dabbing marijuana, this study aimed to gather preliminary information on dabs users and test whether dabs use is associated with more problems than use of flower cannabis. They found that using dabs created no more problems or accidents than using flower cannabis.


05/15/14 | Changes in cigarette and alcohol use during cannabis abstinence

Because marijuana has a lower morbidity and mortality rate than both alcohol and tobacco, researchers wanted to find out if quitting cannabis is associated with substitution with these substances. Results showed that abstaining from cannabis was associated with increases in alcohol and tobacco use, which then decreased with the resumption of cannabis use. There were no increases, however, in individuals who remained abstinent from cannabis at one-month follow-up.


05/15/14 | Prevalence and correlates of alcohol and cannabis use disorders in the United States: Results from the national longitudinal study of adolescent health

A study of over 15,000 people found that lifetime alcohol abuse rates were substantially higher than cannabis abuse and dependence rates. According to the study, lifetime rates of alcohol abuse and dependence were 11.8 and 13.2%. Lifetime rates of cannabis abuse and dependence were 3.9 and 8.3%. The data also showed that alcohol use disorders demonstrated specific sociodemographic correlates while marijuana use disorders did not.


03/03/14 | Marijuana and Workplace Safety: An examination of Urine Drug Tests

With a growing number of states decriminalizing marijuana for medical and recreational use, employee drug testing has become an issue that is gaining more attention. Researchers compared the proportion of marijuana positive urine specimens for post-accident drug tests versus random samples of employees. They found no statistically significant difference between the numbers of laboratory positive marijuana urine drug tests for a group of random drug tests compared to a group of post-accident drug tests.


02/26/14 | Do medical marijuana centers behave like locally undesirable land uses? Implications for the geography of health and environmental justice

Marijuana dispensaries in Colorado are not considered to be locally undesired land uses and do not have any more impact on their neighborhoods than do coffee shops, according to new research. Researchers predicted that dispensaries would change the neighborhoods surrounding them for the worse, and even create more crime, but that just wasn’t the case for Paul Stretesky and his team at the CU Denver School of Public Affairs. “We argued a bit among ourselves and divided the data up every way we could think of to find evidence of inequality where we may have missed it ... It simply looks like these are not as undesirable as they are made out to be in the media and by law enforcement," Stretesky said.
