Summary: This review summarizes the current research topics in cannabis agronomy, focusing on the influence of crop management and environmental conditions on yield and phytocannabinoid production. Understanding these factors is crucial for promoting higher yields and stable production of phytocannabinoids.

Summary: This study uses administrative data from Canada's medical cannabis program and licensed cannabis vendor catalog data to analyze the participation of patients, physicians, and cannabis vendors in the program, as well as trends in medical cannabis consumption, prices, and potency. The study finds that there has been a significant increase in medical cannabis use after policy changes, but a decline in the number of physicians supporting patient cannabis use. The prices of medical cannabis have remained relatively stable and even decreased over time. Future research should focus on the implications of these changes and the legalization of recreational use on patient health outcomes.

Summary: This paper discusses the history, benefits, and risks of cannabis, as well as the background of the federal re-legalization of cannabis for medical use in the USA. Research data show that medical marijuana may help decrease the use of opioids and benzodiazepines, as well as reduce related overdose deaths.

Summary: This study focused on the changes in cannabis use outcomes by race and ethnicity following the enactment of recreational cannabis laws in the US. Findings showed an increase in past-year and past-month cannabis use among Hispanic, other, and non-Hispanic White populations aged 21 years and older after RCL enactment, but no increase in these outcomes for non-Hispanic Black individuals or individuals aged 12 to 20 years. Additionally, there was an increase in the odds of cannabis use disorder among individuals categorized as other overall post-RCL, but no increases were found by age group.

Summary: The majority of Australians support the legalization of medical cannabis, but remain cautious about legalizing recreational cannabis use. Supporters of medical cannabis are more likely to have chronic pain, while supporters of recreational cannabis are more likely to suffer from psychological distress. Recent cannabis users are significantly more likely to support the legalization of both medical and recreational cannabis.

Summary: This observational cohort study examined the effects of cannabis use on symptoms of pain, insomnia, anxiety, depression, and cannabis use disorder (CUD). The study found that cannabis use was not associated with improved pain, anxiety, or depression symptoms, but it did lead to new-onset CUD in a minority of participants.

Summary: This study evaluated the temporal trends and correlates of medical cannabis use in the United States. The analysis of data from 2013 to 2020 showed a significant increase in the prevalence of using cannabis for medical purposes, with an average annual growth rate of 12.9%. Living in a state that legalized medical cannabis remained significantly associated with medical cannabis use.

Summary: The study found that CBD-type cannabis primarily expresses cannabidiolic acid synthase (CBDAS), while cannabis strains with a balanced THC:CBD ratio express both CBDAS and THCAS. Cannabinoid synthase genes are arranged in tandem structure and embedded within long terminal repeat retrotransposons on chromosome 7.

Summary: Five essential oil hemp cultivars were treated with various synthetic fertilizer rates and irrigation electrical conductivity to quantify their effects on plant growth, biomass accumulation, and cannabinoid profiles. Results showed significant variations in plant growth and cannabinoid concentrations among cultivars, with optimal fertilizer rates observed at 50 ppm N. Increased fertilizer rates (>300 ppm N) resulted in compliant THC levels but decreased plant growth and cannabinoid yields. CBD concentration demonstrated higher sensitivity to increased fertilizer rates compared to THC and CBG.

Summary: This study measured the associations between feeling high and treatment outcomes during cannabis consumption. The results showed that feeling high was associated with symptom relief but increased negative side effects. Factors such as plant phenotype, consumption mode, THC and CBD potencies, and dose influenced the intensity of feeling high for individual patients.

Summary: A cross-sectional study found that warning signs policies mandating point-of-sale warnings about the risks of cannabis use during pregnancy did not reduce cannabis use during pregnancy. However, these policies were associated with increased support for punishment and stigma among those who did not use cannabis.

Summary: Recent years have seen a surge in the attention given to high-THC and low-THC cannabis types in various markets. Tissue culture clones offer advantages for cultivation, but there are still variations in responses and the development of methods for elite strains is in its early stages. Research focusing on tissue culture in cannabis is advancing, with potential future strategies for breeding and propagation.

Summary: Marijuana-related businesses face banking problems due to federal illegality, leading to limited access to banking services even when marijuana is legalized. Regulatory uncertainty and risks associated with the cannabis industry further hinder banks from providing financial services to these businesses, despite the potential solutions proposed by changes to federal law.

Summary: The study conducted among Israeli medical, nursing, social work, and other health related students at Ben Gurion University of the Negev revealed a significant lack of preparedness among the students to answer patients' questions about medical cannabis, despite the majority believing in its health benefits and expressing concerns about the risks. The findings underscore the need for more knowledge and formal education on medical cannabis for students pursuing health professions in light of current regulatory and scientific advancements.
