Moreover, clinical trials are strongly required to determine whether the findings in animal models occur in humans diagnosed for cocaine or crack cocaine use disorder. Read

Perception of cannabis health information labels among people who use cannabis in the U.S. and Canada

Results indicate that cannabis users in general perceived product characteristics, quality, and price to be important factors in their willingness to buy cannabis in dispensaries. There were heterogeneities in the perceptions by cannabis use purposes. Read

Pregnancy outcome among women with drug dependence: A population-based cohort study of 14 million births

5/11/20--A study examining the association between drug dependency in pregnancy (DDP) and maternal and newborn outcomes shows an increase in frequency associated with maternal and newborn deaths and adverse events. Further research and public health initiatives have been suggested to be undertaken to address prevention, screening, and treatment. Read

Intensity of cannabis use: Findings from three online surveys

5/1/20--Respondents who reported using cannabis daily (i.e., 30 days in the past month) consumed almost twice as much per day of use on average as did those reporting less than daily. The study finds only modest increases in intensity among those using less than daily, but then a substantial increase (p< 0.001) for those who use daily. Read

Cannabis use during adolescence and the occurrence of depression, suicidality and anxiety disorder across adulthood

Content analysis of online product descriptions from cannabis retailers in six US states

1/1/20--A current study published in the International Journal of Drug Policy examining how cannabis products are described on US cannabis retailer websites concludes that online cannabis retailers are making potentially unsubstantiated product claims.

Modes of cannabis use: A secondary analysis of an intensive longitudinal natural history study

6/24/19--There is a paucity of research on modes of marijuana use (e.g., joint vs. blunt), and further, little consensus on how to accurately assess both modes of use and route of administration. A secondary analysis used a longitudinal design with data collected daily to characterize mode of marijuana use. Although the major limitation of this study was use of a convenience sample and lack of detailed data on vaporizer use, results indicate that joint use is no longer the most common mode of use in either White or Black participants and exclusive use of a single modality is uncommon.

However, the strength of the relationship between vaping and delinquency is contingent on what is being vaped, with marijuana vaping being most heavily correlated with delinquency. Read

Unintentional pediatric marijuana exposures prior to and after legalization and commercial availability of recreational marijuana in Washington State

3/4/19--According to a study presented in The Journal of Emergency Medicine, reported unintentional pediatric marijuana exposure has increased in the state of Washington since recreational marijuana was legalized, which often presents as altered mental status with unknown cause.

Driving under the influence of cannabis among medical cannabis patients with chronic pain

1/9/19--Driving under the influence of cannabis (DUIC) is a public health concern among those using medical cannabis. Understanding behaviors contributing to DUIC can inform prevention efforts. A recent study evaluated three past 6-month DUIC behaviors among medical cannabis users with chronic pain. With more research needed on how to best measure DUIC, prevention messaging for DUIC may be enhanced by addressing alcohol co-consumption. Read
