Upon arrival, subjects were rested for 10—15 minutes, and their baseline blood pressure and heart rate were recorded using a digital blood pressure BP monitor. Participants were given a standardized breakfast, and 15 minutes later, they were given either oral CBD mg or placebo in a double-blind fashion. This is a dose known to cause anxiolytic effects in humans and is comparable with what is used clinically 19 , 37 — Study medication consisted of capsules containing either mg of CBD or excipients, which were a gift from GW Pharmaceuticals.
There was no difference between the 2 formulations in color, taste, or smell. Two hours afterward, subjects were asked to perform the stress tests Timing of the tests was chosen to coincide with peak plasma levels for CBD All the experiments were performed in a sitting position under ambient temperature conditions. Maximum voluntary contraction for the isometric hand grip test was assessed for each subject prior to administering study medication.
After administration of CBD or placebo, subjects remained seated, either doing nothing, reading, or using a computer. During this time, subjects were connected to a calibrated Finometer Finapres Medical Systems , which uses a finger-clamp method to detect beat-to-beat changes in digital arterial diameter using an infrared photoplethysmograph The Finometer gives a continuous signal of beat-to-beat changes in blood pressure and blood flow, and it uses this signal to derive other parameters, including systolic, diastolic, and mean blood pressure; interbeat interval; heart rate and left ventricular ejection time; stroke volume; cardiac output; and systemic peripheral resistance.
Baseline cardiovascular data was recorded for 2 hours following administration of CBD or placebo. Forearm blood flow was measured using a calibrated laser Doppler flowmeter Perimed After 2 hours, subjects underwent the cardiovascular stress tests in the following order: The mental arithmetic test consisted of calculating a sum every 2 second for 2 minutes.
Subjects were seated in front of a computer screen, and a PowerPoint presentation delivered a slide with a simple mathematical sum of a 3-digit number minus a smaller number e. Cardiovascular parameters were measured continuously using the Finometer, while skin blood flow measurements were taken just before, during, and 5 minutes after each test.
Each stress test lasted for 2 minutes, and there was a recovery period of at least 10 minutes. Data were not unblinded until after statistical analysis. Ten healthy young male volunteers, mean age 24 years range 19—29 , with no underlying cardiovascular or metabolic disorders, were recruited for this study, which was approved by the University of Nottingham Faculty of Medicine Ethics Committee study reference E Written informed consent was obtained according to the Declaration of Helsinki.
Exclusion criteria included any significant cardiovascular or metabolic disorder or use of any medication. All the volunteers were nonsmokers and had taken no prescribed or over-the-counter medication within a week prior to randomization. No volunteers had ever used cannabis.

Ischemic, hemodynamic, and neurohormonal responses to mental and exercise stress. Is the cardiovascular system a therapeutic target for cannabidiol? Br J Clin Pharmacol. Rajesh M, et al. Cannabidiol attenuates high glucose-induced endothelial cell inflammatory response and barrier disruption. Cannabidiol attenuates cardiac dysfunction, oxidative stress, fibrosis, and inflammatory and cell death signaling pathways in diabetic cardiomyopathy.
J Am Coll Cardiol. Inflammation appears to play a role in the development of type 1 and type 2 diabetes and other chronic diseases. Some research suggests that the anti-inflammatory properties of CBD can treat the inflammation contributing to diabetes and associated complications.
Diabetic retinopathy is the leading cause of vision loss in those with diabetes. According to the National Eye Institute , it is also the most common cause of blindness in adults of working age. The results of research carried out on animals suggests that 1 to 4 weeks of CBD treatment provided 'significant protection' from diabetic retinopathy. Diabetic neuropathy is a common complication of diabetes. It is a form of nerve damage that occurs most often in the legs and feet, but also in other parts of the body.
Neuropathy can be extremely painful and fatal in some cases. A study on people with neuropathic foot pain suggests that inhaling cannabis can provide relief from diabetic neuropathic pain for several hours. Marijuana use for people with diabetes may have several benefits, but there are also disadvantages. If cannabinoids affect the metabolic system, insulin sensitivity, and appetite, this might also mean that frequent cannabis use could disrupt these functions.
The main disadvantage of using cannabis for diabetes is related to an increased appetite. This is a common side effect, which some people call "the munchies.
This can be an issue for those with diabetes, as carbohydrates cause blood sugar to rise rapidly. Very high blood sugar levels may result in a medical emergency. There are some concerns that marijuana users may not notice their blood sugar levels have dropped when they are intoxicated.
It is also a worry that they may attribute symptoms of low blood sugar to the drug use. Other potential undesirable side effects of marijuana use include:. How the person uses marijuana will affect their risk of adverse effects. Also, smoking marijuana will affect a person differently from using a medical preparation that a doctor has recommended.
Also, since the FDA has not approved the use of marijuana or its compounds for treating diabetes, a person cannot be sure of the ingredients or quality of the product they obtain. It is best to speak to a doctor before using any form of marijuana or other complementary therapy for diabetes. People can apply these directly to their hands and feet using a spray, to reduce the pain and tingling sensations associated with diabetic neuropathy.
A variety of CBD and hemp oils, lotions, and balms are available to purchase online.

Before obtaining or using marijuana for any purpose, people should check if it is legal in their state. It is also best for an individual to ask a doctor's advice to ensure that they can safely use marijuana or any other complementary therapy or supplement.
Medicinal marijuana is a complementary therapy. It is vital to follow the treatment regime for your condition alongside supplemental therapies and not to replace them.
There have been studies that showed how the whole plant was more effective than the single-molecule compounds of one CBD or another. There is some theory that the different parts of the plant work together to boost effectiveness, without increasing dose or side effects.
I think more research will come but, currently, the whole plant is still illegal in many places so using only one component of the plant might be your only legal choice. We picked linked items based on the quality of products, and list the pros and cons of each to help you determine which will work best for you.
