How long does it take for CBD to work? This question might have popped on your mind while selecting a CBD product. The answer to this question is far from absolute because there are several factors to consider. However, we can still come up with a sound theory from what we currently know.  

 CBD’s mechanism of action in the human body 

CBD (cannabidiol), a cannabinoid extracted from the cannabis plant has several interactions upon entering the body. However, it’s key interaction is in the endocannabinoid system, a system in the human body that affects several key biological processes such as inflammation, infection response, and so on [1].  

 There are diverse types of cannabinoids in the cannabis plant, and each of them has a certain strength of affinity to the endocannabinoid system’s receptors, but unlike THC (tetrahydrocannabinol), which elicits a psychoactive effect to the user, CBD potentially has several therapeutic effects too, but without the high [2].  

CBD also interacts with several receptor proteins such as serotonin-receptor 5-HT1A and vanilloid receptor TRPV1 [3, 4]. The encompassing effects of CBD in soothing pain and inflammation is attributed to its ability to interact with the several biological pathways of the body, such as the endocannabinoid system and receptor proteins.

How long until you experience CBD’s effects?

CBD’s response rate differs for each user because there are different factors that dictate how fast the effect will come and go. These factors include dose, body weight, CBD concentration, method of consumption and individual biological factors [5]. The one thing that seems to be uniformed on average is the method of consumption.  

 The time-frames presented below for each type of consumption is not definite. The proposed response rates are merely representations of anecdotal evidence and biological standards collected for this particular topic.  

  1. Inhalation: Inhalation is the fastest route to feel something almost immediately. Because inhalation is a direct administration of a vapour to the lungs down to the bloodstream, the effect typically comes in minutes [6].  
  1. Topical: The topical application applies CBD on a localised area of the skin. The response rate would depend on the type of condition the patient is trying to treat. If it’s the inflammation of the joints, it would just take a couple of minutes or an hour. If it’s stress-related, the body would need more hours to get acquainted with CBD. Some even sleep it out [7]. 
  1. Sublingual application: In the sublingual application, the user drops a tincture of CBD oil under the tongue. Some report the effect to be “almost right away,” but realistically, the method typically renders effect anywhere from 15-60 minutes [8].
  1. Oral: This method refers to the swallowing of a pill or edible and would usually take effect after 90 minutes or so. The oral method takes longer than usual because the capsule has to go through the several processes involved in the digestive system before the bloodstream absorbs it.   

The upside to oral administration is the effects last longer. Ideally, this type of consumption extends the CBD effects up to 6 hours or so [7].
