does cbd hemp oil work

Body fat influences the amount of CBD you need to feel an effect. The larger the body mass, the more CBD required to feel potential effects. Bodyweight and mass also affect how long CBD will remain in your system. Like THC, CBD is stored in fat cells and gradually eliminated from the body through urine and feces.

Bottom line: Ingesting CBD via a tincture or a CBD oil-infused edible will result in a longer onset (up to two hours) and possibly weaker effects.

Metabolism

The most common method for CBD consumption involves administering a couple of drops directly into the mouth. Swallowing the oil will prevent the CBD from immediately entering your bloodstream, sending it instead through the digestive tract and eventually on to the liver, where it is broken down before finally reaching the bloodstream.

You can consume CBD oil sublingually by placing a few drops of CBD under your tongue and rubbing it into the tissue there with your tongue or finger for at least 30 seconds to a minute before swallowing. This will allow the mucous membranes in your mouth to absorb the CBD, partially bypassing the digestive system and liver, for much quicker entry into the bloodstream. Effects may be felt within seconds. Just like when you ingest THC edibles though, you’ll get a second onset of effects a couple of hours later when the CBD that wasn’t absorbed sublingually makes it through your digestive system.

The metabolic rate of the individual also has some sway over how long CBD stays in the system. The body’s metabolism determines the time needed to break down and synthesize compounds, which affects how long it takes the body to process and metabolize the cannabinoid.

For those worried about THC showing up in their system, look for broad-spectrum oil or products that contain pure CBD isolate. Broad-spectrum oil, as opposed to full-spectrum oil, is refined to exclude the trace amounts of THC that may have been present in the hemp plant. Products with CBD isolate contain no THC or other plant-based cannabinoids. To find high-quality CBD, search for products that come with a certificate of analysis from a third-party testing lab to ensure that the information listed on the product label is accurate. Be careful not to confuse hemp seed oil or hemp oil, which seldom contain any CBD at all, with CBD oil. These products will provide a hearty dose of omega-3 fatty acids, but they won’t provide any potential pain-relieving or anti-anxiety effects.

Earlier research found fewer than a third of 84 products studied contained the amount of CBD on their labels. Some users of CBD have also failed drug tests when the product contained more THC than indicated.

However, a double-blind study found healthy volunteers administered CBD had little to no change in their emotional reaction to unpleasant images or words, compared to the placebo group. “If it’s a calming drug, it should change their responses to the stimuli,” said Harriet de Wit, co-author of the study and a professor in the University of Chicago’s department of psychiatry and behavioral neuroscience. “But it didn’t.”

Is CBD harmful?

Up in the wee hours of the night, stuck watching videos of puppies? CBD may be promising as a sleep aid; one of the side effects of the Epidiolex trials for epilepsy was drowsiness, according to Mr. MacKillop, a co-author of a review on cannabinoids and sleep. “If you are looking for new treatments for sleep, that may be a clue,” he said.

For students with generalized social anxiety, a four-minute talk, with minimal time to prepare, can be debilitating. Yet a small experiment in the journal Neuropsychopharmacology found that CBD seemed to reduce nervousness and cognitive impairment in patients with social anxiety in a simulated public speaking task.

“Our top therapies attempt to break the association between reminders of the trauma and the fear response,” said Mallory Loflin, an assistant adjunct professor at the University of California, San Diego and the study’s principal investigator. “We think that CBD, at least in animal models, can help that process happen a lot faster.” While large clinical trials are underway, psychologists say there isn’t compelling evidence yet as to whether this is a viable treatment.
