How Long Does CBD Last

How Long Does CBD Last

 

This figures importantly into how often we want to take CBD.

 

It also hinges on how we take it and with what!

 

That second part is really important in understanding how long it lasts and we'll get into that.

 

It can increase your absorption of CBD 4x's.

 

Of course, all of this hinges on one question…

 

How long does CBD stay in the system?

 

Let's look at this question but also provide detail on the optimum way to take CBD for the most effect.

 

Keep in mind that everyone's body is different.

 

Test and try to see what your effects are.

 

Adjust and repeat.

 

Let's get into it.

 

We'll touch on these areas below:

  • How long does CBD stay active in the body
  • Does how you take CBD affect how long it lasts in the body
  • Does food affect how long CBD stays in the body
  • Do medications affect how long CBD stays in the body
  • Long term effects of CBD in the body

 

Let's get started.

 

What about the initial response or reaction to CBD.

 

How long does CBD stay active in the body?

This partially depends on how you take it (we'll cover next) but here's the general rule:

 

CBD's immediate effects usually last from 2-6 hours

 

For people using CBD for anxiety, pain, sleep, or specific and acute issues, a good benchmark is about 4-6 hours.

 

Studies show that peak CBD blood concentrations occur 4 hours after consumption.

Peak CBD metabolites in urine occur 6 hours after consumption.

 

This means that CBD was "processed" by the liver and other organs within the body.

 

The general effects of CBD on balancing our endocannabinoid system can actually exist for a much longer time.

 

We'll touch on this below.

 

CBD has an immediate effect and a long term cumulative build up as well.

 

Obviously, the immediate effect is what most people are asking about in terms of how long it lasts.

 

Let's look at the processing of CBD in the body.

 

CBD first goes through the P450 pathway in the liver.

 

We can take advantage of this process to not only get more CBD into the system but also to make it last longer.

 

We'll discuss in the food section below how to do this.

 

Otherwise, CBD only has a bioavailability of 6% when taken orally since the liver is aggressively trying to break it down.

 

The "half life" of CBD was actually shown to last 1-2 days.

 

This means that CBD's effects were still present for 1-2 days following a single dose at about ½ the original level.

Does how we take CBD affect it's duration in the body?

 

Does how you take CBD affect how long it lasts in the body

Yes!

 

There are a few basic ways to take CBD:

  • Orally (oils, capsules, edibles, etc)
  • Topically (skin creams, balms, and patches)
  • Inhalation (vape oils, high CBD concentration flower)

 

The means of taking CBD will affect not only how long it lasts, but how quickly it can be felt.

 

Anything that is consumed orally is in for a real battle!

  • Stomach acid
  • Enzymes
  • Gut bacteria

 

And the mother of all battles...our liver!

 

The liver is a ruthless taskmaster bent on breaking down, metabolizing, and getting rid of everything we swallow.

 

CBD is no exception.

 

Orally taking CBD will mean a great deal of it never makes it into the body.

 

There are tricks to offset this which we'll discuss below and at our How to Take CBD article.

 

Here's the general rule of thumb on how long CBD lasts by type:

  • Oral - 4-6 hours
  • Topical - 6+ hours; slower to make it into the body but slower to leave
  • Inhalation - 2-4 hours; fast acting, faster to leave the body

 

For the oral administration (most popular oil tinctures), let's look at how we can get more out of the CBD we do take!

 

Does food affect how long CBD stays in the body?

Yes!

 

In a big way.

 

CBD is metabolized and also eliminated via the P450 pathway in the liver primarily.

 

This is a very busy thoroughfare in the body for breaking things down.

 

The liver is also tasked with metabolizing a great deal of our food...especially fat...through this same pathway.

 

If you take CBD after a meal, preferably your fattiest meal, it can increase the amount of CBD that makes it in to your body by 4x's.

 

It can also stretch how how long CBD lasts in the body by 50%

 

In studies, the blood serum level of CBD would jump from 4 to 6 hours (50%) when taken after food.

 

The studies looked at taking CBD within 2 hours after eating a meal.

 

This is why the MCT or other base oils is so helpful for it's absorption.

 

It needs fat to sneak past the liver's guards!

What about medications?

 

Do medications affect how long CBD stays in the body?

Same thing happens with medications and CBD.

 

Over 60% of common medications use the liver's P450 pathway to be metabolized.

 

For this reason, we want to take CBD at least 2 hours away from medication.

 

In this case, we're not trying to extend how long CBD stays in the body.

 

We don't want the CBD metabolism to interfere with how your medications work!

 

Make sure to check with your doctor of all supplements including CBD in regards to your medication.

We talked about half-lives and immediate effects of CBD….what about long term effects of CBD?

Long term effects of CBD in the body

As we discussed above, CBD's immediate effects appear to last 4-6 hours depending on:

  • How we take CBD
  • If we take CBD after food
  • Our own body's chemistry

 

That's not the end of CBD's story in our body.

 

Research is pointing to a longer effect.

 

In one study on addiction, the positive effects of CBD lasted for 7 days after three dosages!

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4604178/

 

Other studies are showing similar CBD retention in terms of "effects".

 

Of course, there are the much longer term effects.

 

For example, CBD is shown to increase neuroplasticity.

 

This is a fancy word for saying that is helps to build new neurons in the brain.

 

New pathways!

 

This is the holy grail for PTSD, depression, anxiety, and many other disorders.

 

New connections in the brain is obviously going to last longer than 4 hours!

 

We want to hear from you.

 

How long does CBD last for you? At what dosage? How do you take it?
