CBD and Asthma

We are currently getting lots of questions about CBD oil and its effects and benefits with Asthma, so here is a short piece about it.


Currently there are 5.4 million people in the UK who are receiving some form of treatment for asthma. 1.1 million children (1 in 11) and 4.3 million adults (1 in 12) suffer from the condition.

Scary numbers!

Asthma can affect people of all ages, however it mainly starts in childhood, with a small spike in numbers in older adults.

What is Asthma?

Asthma is a long-term condition which affects your airways- these are the tubes which carry air in and out of the lungs.

Someone who is asthmatic has more sensitive airways that reacts once they come into contact with allergens.

Not everyone with asthma will experience it in the same way. We have different triggers and symptoms. It’s important to see what triggers your asthma and what you can do to prevent an attack.

There are different  ‘types’ of asthma too. Occupational asthma, for example triggers at work or school may cause it. Thankfully, only 5% of people with asthma have severe asthma. This type of asthma requires specialist treatment as the usual medicines prescribed for asthma don’t keep the symptoms under control.

Symptoms of Asthma

Asthma may presents differently in everyone. Here’s the main symptoms:

  • – Wheezing (a whistling sound when breathing)
  • – Breathlessness
  • – A tight chest, this may feel like a band it tightening around it
  • – Coughing

These symptoms may sometimes get worse. When this happens an asthma attack occurs.

Asthma attacks tend to happen when the symptoms are worse for a short time. It may happen suddenly or gradually over a few days.

Some of the signs of an asthma attack are:

  • – Wheezing, coughing and chest tightness becoming severe and constant
  • – Too breathless to eat, speak or sleep
  • – Faster rapid breathing
  • – Fast heart beat
  • – Drowsiness, confusion, exhaustion or dizziness
  • – Blue lips or fingers
  • – Fainting

What are the treatments for Asthma?

Presently there is no cure for asthma, but various treatments can help control symptoms so people can live active and normal lives.

Inhalers are typically used to treat asthma. They are devices that let you breathe in the medicine. If people have severe asthma, then they may need tablets or other treatments to help control their symptoms.

There are different types of inhalers people with asthma can get: reliever inhalers, preventer inhalers and combination inhalers. With a severe asthma attack, steroid tablets are often used.

Causes of Asthma

Asthma occurs by inflammation of the breathing tubes’ lining that carries air in and out of the lungs. This makes the tubes very sensitive and they narrow temporarily.

Asthma may also occur randomly or after an exposure to a trigger. Some common asthma triggers are:

  • – Allergies- house dust mites, cat or dog fur or pollen
  • – Smoke, pollution and cold air
  • – Exercise
  • – Infections like cold or flu

By identifying and avoiding asthma triggers can help keep symptoms under control

How does CBD work for Asthma?

Research on CBD has revealed there are many benefits that can help relieve the symptoms of many conditions and diseases. Asthma can be one of them. CBD works in asthma by activating endocannabinoid system receptors.

By activating the CB1 receptors, CBD starts its therapeutic effects. When we take  CBD for asthma, the potential benefits can be a decrease in inflammation, inhibit mucus production, reduce airway obstruction and prevent asthma symptoms.

Cannabis has shown to be helpful to people with asthma in many ways. However, the most prominent research we found shows that cannabis is a bronchodilator, meaning it opens the airways. This shows CBD has a promising positive effect on asthma.
