Whether you’re smoking a high-CBD strain, puffing on a hemp flower pre-roll, or taking a draw from a CBD vape pen, inhalation is often seen as an effective method of delivery for CBD because of how quickly it’s absorbed in the body. When you smoke CBD flower or vape CBD oil, cannabinoids go directly to your lungs where they rapidly enter your bloodstream and circulate throughout your body. CBD reaches peak concentrations within three minutes after consumption, meaning the effects can be felt shortly after use.
Some people may be apprehensive to try CBD over concerns that it could cause them to fail a drug test. It’s highly unlikely that CBD would show up on most drug screenings, as most tests specifically look for the presence of THC and THC metabolites. But even hemp-derived CBD can contain trace amounts of THC, so there’s technically a chance — albeit extremely slim — of receiving a false-positive test result from taking an unusually large dose of CBD oil (estimates range from 1,000 to 2,000 milligrams per day).
The way CBD interacts with and leaves your body depends on several factors that vary from person to person.
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.
CBD also interacts with other receptor proteins not directly related to the ECS, such as the serotonin receptor 5-HT1A and vanilloid receptor TRPV1. Any potential anti-inflammatory and pain-relieving properties of CBD could stem from the activation of these additional biological pathways.
Vaping CBD oil is generally the quickest way to feel the benefits of CBD. When you vape CBD, your lungs quickly absorb the CBD you inhale. From here it quickly enters the bloodstream, where it then travels to various parts throughout the body.
Many people who take CBD in the form of capsules, edibles or drinks prefer to do so on an empty stomach, which can reduce the time it takes for CBD to make its way through the digestive tract and be broken down by the liver. However, consuming capsules or edibles with fatty-acid-rich foods may help increase bioavailability.
Now that you know how long the effects of CBD last, you might be wondering just how much CBD you should take to feel these desired effects. Remember, CBD affects everyone differently and ideal servings will vary tremendously. Like we mentioned before, the best thing you can do is give it some time.
How You Use CBD Determines How Long it Takes to Feel the Effects and How Long the Effects Last
Research indicates the presence of an endocannabinoid system in the skin, which has been associated with several biological processes. Because CBD topicals bypass the digestive tract and liver, the effects can be felt much quicker than when using other methods.
How long it takes CBD to work, as well as how long the effects last, will differ. As a general rule, CBD effects will last between 2-8 hours.
People have a lot of questions about CBD. One of the most common questions we hear:
When you first start taking CBD, it’s best to give your body time to adjust to something new. Start by slowly by taking a low serving size (5–10mg) and then work your way up over the course of a couple weeks until you hit that sweet spot and feel the benefits you desire.
CBD oil and tincture are different, although the words are often used interchangeably. Tinctures are alcohol-based and oils are oil-based.
You can use sublingual administration with CBD oil too, although it takes longer to work and may not be quite as effective. “When you use CBD oil sublingually, your mucus membranes will absorb some of the medication; however, the majority of it will mix with your saliva and be swallowed,” Risola said.
CBD Oil and Tinctures
Exercise is renowned for speeding up the body’s metabolism, so those who exercise on a regular basis will probably experience better results from CBD. Those who don’t exercise, however, are likely to have a sluggish digestive system, and cannabidiol may not provide the relief they’re expecting.
Full-spectrum products contain all of the natural components of the hemp plant, including the miniscule amount of THC native to hemp. Broad-spectrum cannabidiol has had the THC removed, and everything except cannabidiol has been removed from CBD isolate. Neither is going to be as effective as full-spectrum CBD oil, but since they contain no THC they won’t show false positives for pot use, either.
Be aware that you will only experience pain reduction in the area where the topical or transdermal is applied. All of the other forms of CBD, by comparison, provide relief for a wide array of medical conditions throughout the body. You may be vaping CBD for chronic pain, for example, and discover that it also helps with stress management.
