Abstract
Omschrijving
The goal of this study is to perform a double-blind, placebo-controlled study to investigate the efficacy of cannabis, compared to placebo, in medically ill participants seeking relief symptoms such as pain, nausea, and vomiting. Participants who meet criteria for severe conditions will be referred from their clinicians . Cannabis that has a high concentration of cannabidiol, which is a cannabinoid that does not change perception or produce intoxication, and low in Δ-9-THC will be used. In this way, the hope is to maximize the benefit of cannabis, while lowering the possible side effects of cannabis in medically ill participants.
The overall goal of this study is to compare active high cannabidiol (CBD)/ low (−)-trans-Δ9- tetrahydrocannabinol (THC) cannabis vs placebo cannabis in patients with serious medical disorders. Participants will be referred from clinicians and will come to the laboratory daily (3-5 times weekly) for cannabis (15.76% CBD; 3.11% Δ-9-THC) vs placebo (0.0% CBD/ 0.01% Δ-9-THC). The cannabis will be vaporized or smoked as a cannabis cigarette. The participants can choose which option they prefer. The cross-over design will be used where participants receive 2 weeks of active cannabis vs two weeks of placebo in counterbalanced order, with participants blinded to the condition. The outcome measures primarily include measures of pain, with secondary measures of mood, nausea/appetite, quality of life, and the both the potentially positive and negative subjective effects of cannabis (e.g., high, mellow, anxious, paranoid).
