So what causes marijuana allergy?

Marijuana allergy can happen due to several causes. First, each individual has a different body and a system that functions.

For instance, some people report allergic reactions due to the consumption of marijuana. That means they may be allergic to marijuana THC.

Some people may also have cannabis allergies due to CBD oil in some cases, which is used as a medical marijuana product.

On the other hand, some people might be allergic to touching a cannabis plant and can have contact dermatitis.

So, summing up, people often get cannabis allergy in the following ways:

  • By inhaling cannabis pollen (In any way)
  • By secondhand cannabis smoke
  • Touching marijuana (Contact dermatitis)
  • Smoking marijuana or eating (edibles)

If you dig deep, the leading cause of an allergic reaction is your body’s immune system.

Whenever an alien virus or component enters your system, the immune system rings the alarm in the body and tries to wipe it out by giving allergic symptoms.

It is why whether you are allergic to marijuana or any other thing, you will observe similar allergic reactions like runny nose, nasal congestion, and sneezing.

However, it is good that your immune system does not want any alien virus or component to stay in your body.

At the same time, your body gets those allergy symptoms, which you have to deal with that.

Further, if you are too sensitive to smoke cigarettes, it can trigger a severe allergic reaction like lung problems.
