With all the buzz about the reported benefits of cannabiniol, there has been a heavily neglected area of study and research regarding how much to take and how often. The question of how long does CBD last can’t simply be answered as simply as a chart or suggested dosage, mostly because it’s actual effects have not been completely studied.

To explain, though many companies are offering pre-made edibles, CBD oils, sublingual tinctures and flavored liquid with CBD isolate or full spectrum cannabidiol already mixed into it, getting the optimum dosage and absorption requires research and balance as to the effects and accuracy of how its used. While many users are quick to run out and buy a single use ecig or top quality vape pens for weed, getting the most effective dosage of CBD may be as simple as changing your ejuice and using it in a device you already own.

Essentially, every manufacturer of CBD oil and vape juice can provide users with suggested doses at regular intervals that are intended to produce the desired effects. However, without fully understanding the properties or true uses of CBD long term, it’s tough to narrow down the duration for how long it stays in your system from a single dosage. In order to help users better understand how the amount of milligrams they take in and retain, we first have to discuss how bioavailability works.

Cannabinoid Bioavailability — How Long Does CBD Last After Using It?

Typically, each form of cannabiniol users take in will be absorbed into the bloodstream at different intensities, mostly because of how many bodily processes it has to pass through before entering. To explain, the bioavailability of ingested CBD is much lower than sublingually or by inhalation because it has to pass through the gut. When you ingest CBD oil, edibles or other oral forms that aren’t immediately absorbed, the products the active cannabiniol is being carried in have to be processed in order for it to be taken into the bloodstream.

In detail, how long does CBD last when you eat or drink a product that contains it is far less than when you vape it simply because the actual dosage your body receives and retains is much lower requiring less time for the body to process it. While you would imagine that CBD which enters the bloodstream faster would be used up and broken down faster, there is a balance between the bioavailability of the dosage and the time period in which it is run through the human body. More or less, regardless of when it is absorbed into the bloodstream, though it may take longer to process after ingesting it, this is only because it hasn’t begun to be administered since the item it is contained in hasn’t been broken down by stomach acid yet.

Additionally, as mentioned, the act of being moved through further processing methods of the human body means that the intensity of the dosage is lower once it is being run through the circulatory system as well. This effectively means that the amount of CBD the body of the user has to break down is less overall and thus takes less time to run through. Essentially, the duration in which CBD is effective is roughly around 3 to 4 hours before you are able to process another full dose.

Bear in mind, depending on the overall dosage whether you take it orally, inhale top quality pure CBD vape juice or actual flower distillate and concentrate, certain cannabidiol products may take longer to be broken down and thus how long does CBD last can vary as far as exact timing. In terms of lasting remnants that stay in the human body, it can be detectable in the human body for more than 3 to 5 days after use.

Does CBD Last Longer Combined With THC?

There are some users who claim that “full spectrum CBD” products, or those that contain up to 0.3% THC in addition to a range of other plant-related cannabinoids which they believe may help to increase the yield of your absorption and effectivity. In fact, this school of thought was reinforced to some degree by an Israeli study by the Lautenberg Center for General Tumor Immunology using mice as the test subjects. During the course of the trial which studied both CBD isolate and full spectrum CBD, they found that the mice being administered full spectrum cannabidiol experienced higher levels of relief from an induced paw inflammation.

While this may not translate directly to human anatomy, the evidence gathered that applies the molecular introduction of both forms of CBD to the endocannabinoid system does present some results pointing at least to the combined effects of a broad range of cannabinoids working in conjunction. In relation to how long does CBD last it’s important to consider that pure CBD alone contains much of the benefits that the associated cannabinoids in full spectrum does, however, the argument is that the effects are heightened by the occurrence of additional compounds believed to be effective cooperatively. Essentially, the harmony of cannabinoids is purported to assist the efficacy of CBD alone by applying their own specific range of unique benefits.

Of course, there is a lot of complicated supposition and conjecture here that ostensibly puts the carriage before the horse, without effective academic studies using human subjects and real world application, there is no concrete evidence to argue in favor of either CBD isolate or the full spectrum dosage. However, with users from all over the globe arguing in favor of its effectivity from a personal perspective and a recent FDA ruling approving a consumer medical treatment that is rooted in cannabidiol as the active ingredient, the validity of its usage for specific purposes as well as possible future applications are endless and undeniable.

With that in mind, it’s important to realize that how long does CBD last with addition of THC and other cannabinoids can extend the duration of its effects. Additionally, because drug screenings are specifically looking for THC in blood, hair and urine, it may be detectable for over a month after a single application even at the lower dosage which full spectrum contains. Due to the fact that there are multiple forms of tetrahydrocannabinol in full spectrum CBD, there is also the potential for other forms of the compound to turn up in test results. If you’re unsure of how certain amounts of THC will affect your ability to live a full and functional life, it’s best to stick with CBD isolate to ensure you are not augmenting your behavior, motor function or state of mind.
