A preliminary investigation of the simultaneous effects of cannabidiol and caffeine.

Caffeine and cannabidiol (CBD) are commonly consumed by the general population, particularly among young adults; however, there is little research on the simultaneous effects of caffeine and CBD. The present study aimed to examine the simultaneous self-reported effects of caffeine and CBD in young healthy adults. Participants ( = 54) who reported daily caffeine use (> 200 mg) attended one experimental session via Zoom and were assigned randomly to receive caffeine (200 mg) combined with either a placebo or CBD (25, 50, 80, 160, or 240 mg).

A double-blind, randomized, placebo-controlled study of the safety and effects of CBN with and without CBD on sleep quality.

The present study sought to determine the effects of cannabinol (CBN) alone and in combination with cannabidiol (CBD) on sleep quality. This was a double-blind, randomized, placebo-controlled study conducted between May and November 2022. Participants were randomized to receive either (a) placebo, (b) 20 mg CBN, (c) 20 mg CBN + 10 mg CBD, (d) 20 mg CBN + 20 mg CBD, or (e) 20 mg CBN + 100 mg CBD for seven consecutive nights.

A Two-Phase, Dose-Ranging, Placebo-Controlled Study of the Safety and Preliminary Test of Acute Effects of Oral Δ-Tetrahydrocannabivarin in Healthy Participants.

Tetrahydrocannabivarin (THCV) is an understudied cannabinoid that appears to have effects that vary as a function of dose. No human study has evaluated the safety and nature of effects in a wide range of THCV doses. This was a two-phase, dose-ranging, placebo-controlled trial of the Δ isomer of oral THCV in healthy adults.

Cannabidiol Reduces Nicotine Withdrawal Severity and State Anxiety During an Acute E-cigarette Abstinence Period: A Novel, Open-Label Study.

Despite efforts to curb nicotine use, 8.1 million adults in the United States use e-cigarettes. Notably, the majority of nicotine-containing e-cigarette users report wanting to quit in the near future, yet there is a dearth of research surrounding intervention efforts.

Longitudinal Relationship between the Introduction of Medicinal Cannabis and Polypharmacy: An Australian Real-World Evidence Study.

Background: Recent studies recommend medicinal cannabis (MC) as a potential treatment for chronic pain (CP) when conventional therapies are not successful; however, data from Australia is limited. This real-world evidence study explored how the introduction of MC related to concomitant medication use over time. Long-term safety also was examined.
