Abstract Adolescence is an immature but adventurous time period of exploration. Due to rapid developments of the brain with unbalanced release of neurotransmitters, adolescents are prone to impulsivity that may carry out potentially dangerous behaviors. According to the Centers for Disease Control and Prevention, more than one-third of high school students have reported the use of cannabis or marijuana in 2019, and the trend has not declined since. Previous studies have shown that cannabis not only affects cognitive and social behaviors, but also produces psychological responses to stress. In this review, we have summarized recent studies on cannabis-produced effects during the unique period of...

ABSTRACT The therapeutic potential of medical cannabis has garnered significant attention in recent years, prompting an urgent need for a comprehensive understanding of its effectiveness across various health outcomes. This article presents an Evidence Map that systematically summarizes clinical evidence on the use of medical cannabis, including the health conditions it addresses, the interventions employed, and the resulting clinical outcomes. The objective is to map the effectiveness of medical cannabis in relation to a wide range of health outcomes. The systematic review process involved two independent, blinded literature researchers who screened the search output using Rayyan software. For studies deemed relevant, full texts were...

Abstract The cannabis gray market poses significant public health concerns and remains a major threat to consumer and/or potential consumer uptake of regulated cannabis markets in jurisdictions with legal state-sponsored cannabis programs. In this perspective, we provide an overview of the cannabis gray market, and describe an integrated epidemiological and regulatory science framework to study the gray market. Using tobacco regulatory science as a guide, we introduce example cannabis regulatory science research activities as a means to improve the field’s understanding of the cannabis gray market. Cannabis regulatory science is a developing field that can improve...

Abstract Up to 10% of women may use cannabis during pregnancy; this is of concern because constituents of cannabis cross the placental barrier and potentially influence neurodevelopment by acting on cannabinoid receptors in the developing fetal brain. In this context, a recent meta analysis of 13 observational studies found that gestational exposure to cannabis was associated with a small increase in the risk of autism spectrum disorder (ASD; relative risk [RR], 1.30) and with an even smaller increase in the risk of attention deficit/hyperactivity disorder (ADHD; RR, 1.13); the latter finding was probably supported by publication...

ABSTRACT With the partial legalization of high-THC Cannabis sativa across 23 states for recreational use and 38 states for medical purposes in the United States, the Cannabis industry is poised for significant growth. Projected to reach a sales volume of $50.7 billion by 2028, this growth is driven by the trend of lifting Cannabis prohibition. High-THC C. sativa cultivars, containing more than 0.3% delta-9 tetrahydrocannabinol (Δ9-THC) as defined by the 2018 US Farm Bill, are used for both medicinal and recreational purposes. Cannabis sativa is a short day, dioecious, annual plant, where female plants are favored for THC production, which requires seed feminization techniques to ensure an accurate female plant population. This involves using...

Abstract: Cannabis is the most used drug worldwide with an estimated 219 million users. This narrative review aims to explore the adverse effects and therapeutic applications of cannabis and cannabinoids on the eye, given its growing clinical and non-clinical uses. The current literature reports several adverse ocular effects of cannabis and cannabinoids, including eyelid tremor, ptosis, reduced corneal endothelial cell density, dry eyes, red eyes, and neuro-retinal dysfunction. Cannabinoids may transiently impair night vision, depth perception, binocular and monocular contrast sensitivity, and dynamic visual acuity. Cannabinoids are not currently considered a first-line treatment option for any ocular conditions. Δ-9-tetrahydrocannabinol been shown to result in...

Abstract Objectives As a growing body of research has linked cannabis consumption and problematic Internet use (PIU), more insight is needed to interpret this association. This scoping review aims to summarize the available literature on PIU and cannabis consumption and to underlie future avenues of research. Methods We conducted an electronic search including all papers published from database inception until May 2023, using keywords related to PIU and cannabis use in the following databases: Academic Search Complete, APA PsychInfo, PubMed, SocINDEX, MEDLINE, CINAHL, and Psychology and Behavioral Sciences Collection. Studies eligible for this review had to meet the following criteria: (1) the primary theme...

Abstract Background With aging emerging as a global challenge linked to chronic diseases, identifying interventions that support a healthy lifespan and health span has become imperative. Cannabinoids derived from cannabis, particularly cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC), have gained attention for their potential to promote healthy aging through interactions with the endocannabinoid system. While CBD has often been highlighted for its benefits, emerging evidence indicates that THC, under certain conditions and doses, may also play a therapeutic role in aging. Despite this interest, significant knowledge gaps persist in understanding cannabis’s role in promoting healthy aging and longevity. Aim We reviewed recent literature to investigate the...

In particular, there is a growing need to understand the impact of cannabis and delta-9-tetrahydrocannabinol (THC) on brain and behavioral health across the lifespan. Materials and Methods: We conducted a narrative review summarizing the effects of cannabis and THC across three stages of life: in utero, adolescence, and late adulthood. We also provide an up-to-date report on past 30-day cannabis use and risk perceptions from the National Survey on Drug Use and Health (NSDUH; 2002–2023) during pregnancy, adolescence, and late adulthood. We note...

Abstract Cannabis sativa L. is gaining attention as a multifunctional species for environmental remediation due to its high biomass productivity, pollutant tolerance, and versatility. This review synthesizes its application across three environmental media: soil, water, and air. In soil systems, hemp has been investigated for the remediation of heavy metals, organic pollutants (f.ex., PAHs), and radionuclides, via mechanisms such as phytoextraction, rhizodegradation, and phytostabilization. Aquatic applications include biosorption (using raw and chemically modified hemp-derived materials to remove nutrients, heavy metals, dyes, and pharmaceuticals), hydroponic phytoremediation of landfill leachate, and field cultivation with treated wastewater irrigation. The review analysis reveals that hemp-based soil remediation, particularly for heavy metals, is the most developed...
