Characterising 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 et al., 2019

Characterising 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.

Beta-Caryophyllene, a CB2-Receptor-Selective Phytocannabinoid, Suppresses Mechanical Allodynia in a Mouse Model of Antiretroviral-Induced Neuropathic Pain, Esraa Aly et al.,

Beta-Caryophyllene, a CB2-Receptor-Selective Phytocannabinoid, Suppresses Mechanical Allodynia in a Mouse Model of Antiretroviral-Induced Neuropathic Pain Esraa Aly, Maitham A. Khajah and Willias Masocha Molecules, 2020, 25, 106; doi:10.3390/molecules25010106   Abstract : Neuropathic pain associated with nucleoside reverse transcriptase inhibitors (NRTIs), therapeutic agents for human immunodeficiency virus (HIV), responds poorly to available drugs. Smoked cannabis was reported to relieve HIV-associated neuropathic pain in clinical trials. Some constituents of cannabis (Cannabis sativa) activate cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2) receptors. However, activation of the CB1 receptor is associated with side eects such as psychosis and physical dependence. Therefore, we investigated the effect of B-caryophyllene (BCP), [...]

As CBD Oil Flirts with Mainstream, Questions Mount, Kathleen Doheny, Medscape, 2018

As CBD Oil Flirts with Mainstream, Questions Mount Kathleen Doheny Medscape, June 11, 2018 Anxiety is a given for Jessica Singer, 25, who juggles her job at a marijuana dispensary with her night-time gigs as a stand-up comedian in Los Angeles. So when it’s time for bed, "I can't turn off my brain,'' she says. Now she does, with the help of a new bedtime ritual -- a ''snack" of two gummy bears containing CBD. CBD, or cannabidiol, is a substance from marijuana that lacks the ''high'' of the THC (tetrahydro-cannabinol) also found in marijuana. The remedy is affordable for her -- about $35 [...]

‘Standard THC units’: a proposal to standardize dose across all cannabis products and methods of administration, T.P. Freeman & V.Lorenzetti, 2019

'Standard THC units': a proposal to standardize dose across all cannabis products and methods of administration T.P. Freeman, V.Lorenzetti Addictions, 2019, Oct 12. doi : 10.1111/add.14842 © 2019 Society for the Study of Addiction. Abstract BACKGROUND AND AIMS : Cannabis products are becoming increasingly diverse, and vary considerably in concentrations of ∆9 -tetrahydrocannabinol (THC) and cannabidiol (CBD). Higher doses of THC can increase the risk of harm from cannabis, while CBD may partially offset some of these effects. Lower Risk Cannabis Use Guidelines currently lack recommendations based on quantity of use, and could be improved by implementing standard units. However, there is currently no consensus on [...]

Regular Cannabis Use Linked to Cardiac Abnormalities, Fran Lowry, Medscape, 2019.

Regular Cannabis Use Linked to Cardiac Abnormalities Fran Lowry Medscape - Dec 30, 2019. https://www.medscape.com/viewarticle/923220?nlid=133282_2052&src=WNL_mdplsnews_200103_mscpedit_psyc&uac=292598PZ&spon=12&impID=2232271&faf=1 Regular recreational use of cannabis is associated with potentially adverse features of left ventricular size and subclinical impairment of left ventricular function, compared with rare or no cannabis use, an observational study concludes. Previous use of recreational cannabis was not associated with such features, suggesting that any deleterious effects may not be permanent. "These are early data which included a relatively small group of regular cannabis users, and the changes we detected were subtle," lead author Mohammed Y. Khanji, MBBCh, PhD, William Harvey Research Institute, NIHR Barts Biomedical Center, Queen Mary University of London, and [...]
