In vitro studies have reported that activation of the CB1 receptor by anandamide can negatively affect human sperm motility, capacitation and the acrosome reactionReference 1471Reference 1472Reference 1474Reference 1475. Hyper- as well as hypo-activation of the CB2 receptor in male germ cells has been shown to disrupt the temporal dynamics of the spermatogenic cycleReference 1476. A cross-sectional study of 86 men presenting at an infertility clinic reported that seminal plasma anandamide levels were significantly lower in men with asthenozoospermia or oligoasthenoteratozoospermia compared with normozoospermic menReference 1471.
However, tolerance to the effects of cannabis develops rapidly after only a day or two of repeated exposure. Chronic marijuana use is associated with a decrease in HR, disappearance of orthostatic hypotension, increase in blood volume, and decrease in the circulatory responses to exercise which are consistent with reduced sympathetic and increased parasympathetic activity .
Once you find one that sounds good you look at their lab reports and find the extraction was done with chemicals. A little off subject… but locally I have heard of two people getting off of their high blood pressure medication after getting a prescription for Medical Cannabis. Not just any strain is good for every condition and I don’t think doctors/dispensaries are educating people as much as they need to.
Furthermore, inter- and intra-species differences in animals with respect to anorexia nervosa-like behaviour have to some extent hampered pre-clinical research on the effects of Δ9-THC in this disorder. Despite the findings of the above-noted study, AIDS-related anorexia associated with weight loss was an approved indication in Canada for dronabinol (Marinol®) (no longer available in Canada). The Marinol® product monograph summarizes a six-week, randomized, double-blind, placebo controlled-trial in 139 patients, with the 72 patients in the treatment group initially receiving 2.5 mg dronabinol twice a day, then reducing the dose to 2.5 mg at bedtime due to side effects (feeling high, dizziness, confusion and somnolence)Reference 654. Over the treatment period, dronabinol significantly increased appetite, with a trend towards improved body-weight and mood and a decrease in nausea.
According to some studies, about 20% of epilepsy patients are actively using cannabisReference 722Reference 731Reference 751Reference 752. A telephone survey of 136 patients of a Canadian tertiary care epilepsy centre revealed that 48% had used cannabis in their lifetime, 21% were active users, 13% were frequent users (one day per week or more), and 8.1% were heavy users (every other day or more)Reference 752.
The medical community is very good at dispensing pharmaceuticals and surgical procedures for AF. Unfortunately for those afflicted with AF, neither drugs or where to buy hemp oil surgeries address the cause and leave the patient at risk for serious illness and even death. Atrial fibrillation (AF) is an abnormal heart rhythm that affects the lives of millions of Americans.
On the other hand, CBD induces other enzymes in this family, which speeds the breakdown of certain drugs so they may potentially be less effective unless the dose is increased. We put commonly asked questions to Nina M. Bemben, PharmD, BCPS, a specialist in drug interactions who is trying to educate other pharmacists about possible drug-drug interactions with CBD, as well as Rachna Patel, DO, a physician who does consultations about medical marijuana and CBD and sells her own line of CBD products. CBD (cannabidiol) is seemingly everywhere, with oils, tinctures, pills, chocolates, gummy bears, and creams available all over the internet, at national drugstore chains, and perhaps at your local farmer’s market — even if you don’t live in a state where medical or recreational marijuana is legal. Having high cholesterol is a risk factor for a heart attack, which can also impact the heart rate. High blood pressure can interfere with the electrical system that regulates a steady heartbeat.
Plasma Cmax of 11-hydroxy-THC was 5.6 and 12.8 ng/mL for the 2.9 and 6.7% doses, respectively. A number of studies have examined the neurophysiological, cognitive, subjective, or behavioural effects of varying the concentrations of Δ9-THC, CBD, or other cannabinoids such as CBC in smoked cannabisReference 128Reference 137. In another study, the subjective effects associated with the smoked or oral administration of cannabis plant material were directly compared to those associated with smoked or oral administration of Δ9-THC (using matched doses of Δ9-THC) to normal, healthy subjectsReference 137. This double-blind, placebo-controlled, within-subject, crossover clinical study reported few reliable differences between the THC-only and whole-plant cannabis conditionsReference 137. They also hypothesized that whole-plant cannabis and THC alone could differ on other outcome measures more relevant to clinical entities (e.g. spasticity or neuropathic pain).
