“Background: Cannabis use is increasing, including among smokers, an at-risk population for cancer. Research is equivocal on whether using cannabis inhibits quitting cigarettes. The current longitudinal study investigated associations between smoking cannabis and subsequently quitting cigarettes.
Results: Adjusted cigarette quitting rates at follow-up did not differ significantly by baseline cannabis smoking status [never 36.2%, 95% confidence interval (CI), 34.5%-37.8%; former 34.1%, CI, 31.4%-37.0%; recent 33.6%, CI, 30.1%-37.3%], nor by frequency of cannabis smoking (low 31.4%, CI, 25.6%-37.3%; moderate 36.7%, CI, 30.7%-42.3%; high 34.4%, CI, 28.3%-40.2%) among recent baseline cannabis smokers. In cross-sectional analyses conducted at follow-up the proportion of cigarette smokers intending to quit smoking cigarettes in the next 30 days did not differ by cannabis smoking status (p=0.83).
Conclusions: Results do not support the hypothesis that cannabis smoking inhibits quitting cigarette smoking among adults.”

“Background: 
“Extracellular Vesicles (EVs) were isolated from human umbilical cord mesenchymal stem cells (hUCMSCs) and were further encapsulated with cannabidiol (CBD) through sonication method (CBD EVs). CBD EVs displayed an average particle size of 114.1±1.02 nm, zeta potential of -30.26±0.12 mV, entrapment efficiency of 92.3±2.21% and stability for several months at 4 °C. CBD release from the EVs was observed as 50.74±2.44% and 53.99±1.4% at pH 6.8 and pH 7.4, respectively after 48 h. Ourin-vitrostudies demonstrated that CBD either alone or in EVs form significantly sensitized MDA-MB-231 cells to doxorubicin (DOX) (*P<0.05). Flow cytometry and migration studies revealed that CBD EVs either alone or in combination with DOX induced G1 phase cell cycle arrest and decreased migration of MDA-MB-231 cells, respectively. CBD EVs and DOX combination significantly reduced tumor burden (***P<0.001) in MDA-MB-231 xenograft tumor model. Western blotting and immunocytochemical analysis demonstrated that CBD EVs and DOX combination decreased the expression of proteins involved in inflammation, metastasis and increased the expression of proteins involved in apoptosis. CBD EVs and DOX combination will have profound clinical significance in not only decreasing the side effects but also increasing the therapeutic efficacy of DOX in TNBC.”

“In humans, various sites like cannabinoid receptors (CBR) having a binding affinity with cannabinoids are distributed on the surface of different cell types, where endocannabinoids (ECs) and derivatives of fatty acid can bind. The binding of these substance(s) triggers the activation of specific receptors required for various physiological functions, including pain sensation, memory, and appetite. 
“Melanoma is one of the most aggressive malignances in human. Recently developed therapies improved overall survival rate, however, the treatment of melanoma still remains a challenging issue.
