“These data indicate that cannabinoids have robust diuretic effects in rats that are mediated via CB1 receptor mechanisms. Overall, our data indicate that diuresis is a CB1-mediated effect that may serve as a reliable and objective physiologic measure of cannabinoid action in rats; the circumstances under which these results represent a potential therapeutic benefit or potential liability of cannabinoids remain to be determined. The implications of these findings currently are poorly understood, although a better understanding of mechanisms and sites of action by which cannabinoids increase urine loss may lead to the rational development of novel cannabinergic medications.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3533417/
“Diuretics are medicines that help reduce the amount of water in the body. Diuretics are used to treat the buildup of excess fluid in the body that occurs with some medical conditions such ascongestive heart failure, liver disease, and kidney disease. Some diuretics are also prescribed to treat high bloodpressure. These drugs act on the kidneys to increase urine output. This reduces the amount of fluid in the bloodstream,which in turn lowers blood pressure.” http://medical-dictionary.thefreedictionary.com/diuretics

“Increased food consumption following ∆(9)-tetrahydrocannabinol-induced cannabinoid type 1 receptor agonism is well documented.
However, possible non-∆(9)-tetrahydrocannabinol phytocannabinoid-induced feeding effects have yet to be fully investigated. Therefore, we have assessed the effects of the individual phytocannabinoids, 
“The physiological control of appetite and satiety, in which numerous neurotransmitters and neuropeptides play a role, is extremely complex. Here we describe the involvement of endocannabinoids in these processes.
These endogenous neuromodulators enhance appetite in animals.
The same effect is observed in animals and in humans with the psychotropic plant cannabinoid Delta(9)-tetrahydrocannabinol, which is an approved appetite-enhancing drug.
The CB(1) cannabinoid receptor antagonist SR141716A blocks the effects on feeding produced by the endocannabinoids. If administered to mice pups, this antagonist blocks suckling.
In obese humans, it causes weight reduction.
Very little is known about the physiological and biochemical mechanisms involved in the effects of Delta(9)-tetrahydrocannabinol and the cannabinoids in feeding and appetite.”
“Cannabinoid type 1 receptor-mediated appetite stimulation by Δ⁹tetrahydrocannabinol (Δ⁹THC) is well understood.
Recently, it has become apparent that non-Δ⁹THC phytocannabinoids could also alter feeding patterns.
Here, we show definitively that non-Δ⁹THC phytocannabinoids stimulate feeding.
Twelve male, Lister-Hooded rats were prefed to satiety prior to administration of a standardized cannabis extract or to either of two mixtures of pure phytocannabinoids (extract analogues) comprising the phytocannabinoids present in the same proportions as the standardized extract (one with and one without Δ⁹THC). Hourly intake and meal pattern data were recorded and analysed using two-way analysis of variance followed by one-way analysis of variance and Bonferroni post-hoc tests.
Administration of both extract analogues significantly increased feeding behaviours over the period of the test. All three agents increased hour-one intake and meal-one size and decreased the latency to feed, although the zero-Δ⁹THC extract analogue did so to a lesser degree than the high-Δ⁹THC analogue.
Furthermore, only the analogue containing Δ⁹THC significantly increased meal duration.
The data confirm that at least one non-Δ⁹THC phytocannabinoid induces feeding pattern changes in rats, although further trials using individual phytocannabinoids are required to fully understand the observed effects.”
