How Long Does CBD Stay in Your System?

Many people are hesitant to ingest CBD thinking of a possible drug test. Stigmas remain regarding the use of cannabis-derived products in some places even though more and more it is recognized that people benefit from the therapeutic properties of the derivative CBD.

CBD is a non-intoxicating substance found in the cannabis plant, used to treat anything from chronic pain to anxiety and depression. Although most people are only tested for THC, CBD does stay in your system for a time.

Determining Factors of How Long Weed Stays in Your System

Several factors that determine how long CBD stays in your system:

How frequently you use it:

CBD is recommended to be used for a week or more so as to provide therapeutic effects. CBD is a substance that needs to build up in your body. Consequently, this means that it is also detectible for a longer period.


The more you take at once, the longer it stays in your system. There is a direct correlation between the dose and how long this cannabinoid is detectable.

How it was administered:

The effects and amount of CBD in your system are also determined by how it was administered. If inhaled, it is more immediate, whereas, if ingested, it takes an hour or two more before you feel any effect.

A study conducted in 2005 did determine that CBD was only detectable in the blood for 9 hours after ingestion.

What else you’ve ingested:

You metabolize CBD faster on an empty stomach. It is also eliminated faster on an empty stomach. On a full stomach, the digestion is slowed down. Both the effect and how long it stays in your system are delayed.

What form it is in:

The way you choose determines the onset of the effect and how long it stays in your system. Various forms include:

  • Lotions and Creams
  • Smoking or Vaping
  • Edibles (like food items or drinks)
  • Capsules or Pills
  • Tinctures and oils

When you smoke or vape CBD, the effect is faster. It also leaves the body faster. Tinctures placed under the tongue may enter the bloodstream faster, but the CBD also lingers longer.

Slower processes are either edibles, which need to be digested, taking longer for the effects to be felt, and absorbing CBD through the skin with the use of creams and lotions. These are lengthier processes, both in effect and expulsion.

Your physiology: Your particular body is unique from others. Your experience is determined by your body mass index, water content, and metabolism. These are all influential factors as to how long CBD stays in your particular system.


It is unlikely that CBD will show up on a drug test. Drug tests are typically devised to detect THC levels. Substance Abuse and Mental Health Services (or SAMHSA) guidelines include THC detection but not CBD. So, it is unlikely that you will fail a drug test by using hemp-extracted CBD oil.

The SAMHSA has established that if your THC level is 50 nanograms per milliliter (or on-billionth of a gram), you will pass your drug test. This means that to fail a drug test, you’d have to take an extremely high dose of full-spectrum CBD oil (from 1,000 to 2,000 milligrams per day).

Also, dispensaries and reputable manufacturers that utilize a third-party dispensing lab to assure that the CBD is a “broad-spectrum oil” or contain just the pure CBD isolate are the safest bet.
