Daily associations with cannabis use and sleep quality in anxious cannabis users

/by

Cannabis is increasingly used to self-treat anxiety and related sleep problems, without clear evidence of either supporting or refuting its anxiolytic or sleep aid effects. In addition, different forms of cannabis and primary cannabinoids ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have differing pharmacological effects.Cannabis is increasingly used to self-treat anxiety and related sleep problems, without clear evidence of either supporting or refuting its anxiolytic or sleep aid effects. In addition, different forms of cannabis and primary cannabinoids ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have differing pharmacological effects.Thirty days of daily data on sleep quality and cannabis use were collected in individuals who use cannabis for mild-to-moderate anxiety (n = 347; 36% male, 64% female; mean age = 33 years). Participants self-reported both the form (flower or edible) and the ratio of THC to CBD in the cannabis used during the observation period.

CBD as a Physiological Modulator for Cancer

/by

The current standard-of-care treatment regimens for cancer frequently have serious and irreversible adverse effects. Ideally, therapeutic modalities should help control symptoms and improve the patient’s quality of life while causing minimal or no toxic effects. In this regard, it is worth examining cannabidiol (CBD) for its potential anticancer properties. CBD may possess antitumor activity through several mechanisms, including regulating reactive oxygen species, endoplasmic reticulum stress, inflammation, and immune modulation. In addition, pre-clinical studies indicate that CBD is a potential modulator of growth factors and induces apoptosis in tumor cells. This review summarizes the evidence regarding the effects of CBD as a non-toxic adjuvant in cancer care.

Driving Under the Influence of Cannabis: Impact of Combining Toxicology Testing with Field Sobriety Tests

/by

Limited data are available regarding marijuana smoking’s impact on development or progression of chronic obstructive pulmonary disease (COPD) in middle-aged or older adults with a variable history of tobacco cigarette smoking. We divided ever-tobacco smoking participants in the Subpopulations and Intermediate Outcomes in COPD Study (SPIROMICS) into three groups based on self-reported marijuana use: current, former or never marijuana smokers (CMS, FMS or NMS, respectively). Longitudinal data were analyzed in participants with ≥2 visits over a period of ≥52 weeks.
