December 20, 2021

CBD for anxiety relief has surged in popularity due to its natural effects. But how fast does CBD oil start relieving anxiety symptoms?

This article explains how CBD helps calm anxiety, the optimal dosage, and why an official diagnosis is recommended for anxiety disorders.

By the end, you'll understand what to expect when using CBD oil to ease anxiety quickly. The key is finding your optimal CBD dosage and routine for managing anxious thoughts and feelings effectively.


Is it Just Anxiety or Something More?

You might think of anxiety when people have panic attacks and worry too much over a topic; these are some symptoms, but they are not all that anxiety is.

An anxiety disorder must first be diagnosed by a medical professional before receiving treatment. Symptoms such as: feeling fatigued, having difficulty concentrating, being easily irritated, muscle tension, sleep problems like sleeping too much, and feeling not well-rested or not sleeping (insomnia), along with excessive worry and fear, can indicate you are suffering from anxiety.

PTSD (Post Traumatic Stress Disorder), Panic attacks, OCD (Obsessive-Compulsive Disorder), Generalized Anxiety Disorder, Social Phobia  (Social Anxiety Disorder) are some of the anxiety disorder types. A proper diagnosis has to be performed to identify what anxiety disorder you might be suffering from. It is good to consult your doctor for a complete diagnosis and take the opportunity to speak about CBD oil for anxiety as an alternative treatment.


Anxiety Diagnosis

If you wonder what you can expect during an anxiety diagnosis, here we have listed some of the crucial points that can give you an idea of what can happen during your consultation.

  • A specialist performs a physical exam to diagnose an anxiety problem. Can suggest a blood test to assist the doctor in establishing whether another condition is causing the anxiety.
  • The doctor may inquire about any medical prescription you are currently taking to see whether any medications may be causing the anxiety. The doctor may also ask about other medical disorders.
  • A psychological evaluation and a questionnaire are to be completed. This questionnaire will include questions such as how your symptoms influence your life? When they began?, how long they have lasted?, how severe they are?, if they have occurred previously?, etc.
  • Anxiety symptoms can also be triggered by post-traumatic stress disorder and eating problems. Your doctor will refer you to a specialist in the field to assess you properly.

After the expert has evaluated your symptoms and family history, they will conduct a feedback session in which you and the doctor will discuss the diagnosis; at this point, you can speak with your doctor about the best CBD for anxiety under your specific needs. A good assessment can help you have a more natural approach to your treatment.


CBD and Anxiety, how do they work?

After being diagnosed with an anxiety disorder, cognitive-behavioral therapy is one of the treatments usually involved to treat anxiety. In addition and also a crucial aspect for treating anxiety is that you understand how your brain works and how anxiety acts. Knowing this can help you ease many worries and reduce anxiety levels caused by the thought of going crazy.

One of the areas in the brain that get triggered during a fight or flight response and can be seen in brain scans is the amygdala, located in the temporal lobe of the brain, responsible for emotion, memory, and the fight-or-flight response. The amygdala has extensive connections that can influence other systems.  Its primary purpose is to initiate a well-coordinated response to danger, and each person can have a more or less sensitivity to danger amygdala.

Another critical area of the brain is the frontal lobe. This part is responsible for emotions, problem-solving, critical thinking, planning, and recognizing parts of speech. When the amygdala is activated due to a fight or flight response, it can overrun the frontal cortex. When an anxiety episode is involved, the frontal cortex cannot produce a reaction to help cope with the situation or thought that triggered the anxiety, and the amygdala with fears, memories, and emotions has responses that are not logical, making it difficult for your frontal cortex to use logic, to overcome episodes of anxiety.

Anxiety seems to be triggered due to a chemical unbalance. There are different neurotransmitters involved in anxiety and according to research “ A variety of neurotransmitters modulates the neuroanatomic circuits that support fear and anxiety behavior. Neurotransmitters like GABA, Adenosine, Melatonin, and neuroactive steroids are anxiolytics. Glutamate, Serotonin, Acetylcholine, Cholecystokinnin, and Corticotrophin releasing hormone are anxiogenic."

CBD is a cannabinoid found naturally in cannabis plants. It can interact with the endocannabinoid system through receptors CB1 and CB2. The receptor CB1, in particular, is abundant in the brain, neocortex, hippocampus, basal ganglia, amygdala, striatum, cerebellum, and hypothalamus. Through further research, CBD can help balance neurotransmitters like GABA or increase production like Serotonin. A supplement of CBD for anxiety and depression is recommended if you are looking for a natural approach. The way CBD interacts in your brain and the benefits it offers is still under research; every year more studies are conducted to understand exactly how CBD can provide a broad of benefits.


CBD for Anxiety: How Fast are its Effects?

According to some research, CBD  activates the parasympathetic nervous system, which aids in slowing the body's stress reaction. As a result, there is some preliminary evidence that it may assist in managing symptoms of severe anxiety.

When taking CBD for anxiety, you can find different methods. How long it will take CBD to relieve anxiety will be influenced by methods and factors such as weight, metabolism, health goals, eating habits, and tolerance to CBD.

  •  Sublingual method with CBD tinctures or sprays. Most people prefer to let it absorb under the tongue. This is because CBD is more effective when apply sublingually, where tissues connect to the bloodstream, and CBD can reach the ECS in less time. The estimated time it takes to have an effect is around 20 to 30 minutes.
  • Oral method with CBD capsules. Individuals find it easier, with no flavor and consistent dosage with a CBD capsule. The estimated time it takes to have an effect is around 40 min to 2 hrs.
  • Oral methods with CBD edibles. A sweet treat is enjoyable for everyone, and specially with CBD infused in sweets like gummies and chocolates, also power bars are available as a more healthier option and less sweet. The estimated time it takes to have an effect is around 40 min to 2 hrs.
  • Topical method with CBD rollers, body balms, bath salts, etc. Some people find it very enjoyable to relieve symptoms from the body with CBD oil and essentials oils infused in bath salts. The skin can absorb CBD and offer a more localized relief from anxiety symptoms, like stiff muscles. The estimated time it takes to have an effect is around an hour to two hours.

Remember that the long-term benefits of CBD oil may take some time to manifest. Start with a smaller dose for a few days before gradually increasing to a greater amount. Until you're familiar with how the products impact you, it's a good idea to keep note of how much CBD you're taking and whether or not your symptoms have improved. This allows you to get a specific CBD dosage for your anxiety. Here you can find our dosage calculator, for a more accurate number.


Nano CBD as an Option for Faster Anxiety Relief

Nano-CBD is created using an ultrasonic processing method in which CBD is encapsulated in a nano structure. The process emulsifies the cannabis, allowing it to be spread evenly throughout a liquid.

Nano Technology is up to 50 x more accessible than CBD-rich hemp oil due to its water-like soluble and nano particle size (range from 50 to 300 nano size), which can easily pass through the cell membrane. The more CBD reaches the ECS, the less CBD oil you need to have the same therapeutic benefits as regular CBD oil.

Nano CBD benefits:

  • Higher bioavailability
  • Higher bio-activity
  • Fast-acting, less than 7 minutes
  • Water like soluble property
  • Even dispersion in products

Nano CBD is an excellent option for fast-acting anxiety relief and other health issues like chronic pain, skin conditions, and more. While also having a faster absorption rate, nano CBD has higher bio-activity, meaning more CBD reaches the Endocannabinoid system while providing wider benefits with less dosage.
