Cannabis and the developing brain : Insights from behavior Viviana Trezza, Vincenzo Cuomo, Louk J.M.J. Vanderschuren European Journal of Pharmacology, 2008, 585, 441-452. Doi : 10.1016/j.ejphar.2008.01.058 A B S T R A C T The isolation and identification, in 1964, of delta-9-tetrahydrocannabinol (THC), the primary psycho-active compound in cannabis, opened the door to a whole new field of medical research. The exploration of the therapeutic potential of THC and other natural and synthetic cannabinoid compounds was paralleled by the discovery of the endocannabinoid system, comprising cannabinoid receptors and their endogenous ligands, which offered exciting new insights into brain function. Besides its well-known involvement in specific [...]
Lire la suiteDevelopmental consequences of perinatal cannabis exposure : behavioral and neuroendocrine effects in adult rodents Patrizia Campolongo, Viviana Trezza, Patrizia Ratano, Maura Palmery & Vincenzo Cuomo Psychopharmacology, 2011, 214, 5–15 Doi : 10.1007/s00213-010-1892-x Abstract Rationale : Cannabis is the most commonly used illicit drug among pregnant women. Since the endocannabinoid system plays a crucial role in brain development, maternal exposure to cannabis derivatives might result in longlasting neurobehavioral abnormalities in the exposed offspring. It is difficult to detect these effects, and their underlying neurobiological mechanisms, in clinical cohorts, because of their intrinsic methodological and interpretative issues. Objectives : The present paper reviews relevant rodent studies examining the [...]

OBJECTIVES : To examine the associations between RML enactment and changes in marijuana use, frequent use, and CUD in the United States from 2008 to 2016. DESIGN, SETTING, AND [...]
Lire la suiteCharacterising heterogeneity in the use of different cannabis products : latent class analysis with 55 000 people who use cannabis and associations with severity of cannabis dependence Sam Craft, Adam Winstock, Jason Ferris, Clare Mackie, Michael T. Lynskey and Tom P. Freeman Psychological Medicine, 2019, 1–10. doi : 10.1017/S0033291719002460 Abstract Background. As new cannabis products and administration methods proliferate, patterns of use are becoming increasingly heterogeneous. However, few studies have explored different profiles of cannabis use and their association with problematic use. Methods. Latent class analysis (LCA) was used to identify subgroups of past-year cannabis users endorsing distinct patterns of use from a large international sample [...]

Doi : 10.1159/000503456 Abstract Background : Several studies suggested the association between tobacco and cannabis smoking and the risk of primary spontaneous pneumothorax (PSP), but none demonstrated cannabinoids in human lung tissues. Objectives : The aim of this study was to identify cannabinoids in lung specimens of young cannabis smokers, operated [...]

Lire la suiteProlonged Cannabidiol Treatment Effects on Hippocampal Subfield Volumes in Current Cannabis Users Camilla Beale, Samantha J. Broyd, Yann Chye, Chao Suo, Mark Schira, Peter Galettis, Jennifer H. Martin, Murat Yücel and Nadia Solowij Cannabis and Cannabinoid Research, 2018, 3, 1, 94-107. Doi : 10.1089/can.2017.0047 Abstract Introduction : Chronic cannabis use is associated with neuroanatomical alterations in the hippocampus. While adverse impacts of cannabis use are generally attributed to D9 tetrahydro-cannabinol, emerging naturalistic evidence suggests cannabidiol (CBD) is neuroprotective and may ameliorate brain harms associated with cannabis use, including protection from hippocampal volume loss. This study examined whether prolonged administration of CBD to regular cannabis users [...]
