Are there Side Effects to CBD?

Changes In Appetite

CBD has been shown to reduce and increase appetite.

Scientists conducting epilepsy studies found CBD primarily reduced a persons appetite, with the exception of those utilizing a high-CBD strain of medical cannabis.

Diarrhea

While not a common side effect, around 20% of people in the epilepsy study experienced diarrhea.

Drowsiness

One of the more commonly reported side effects is drowsiness caused by CBD. Nearly 20% of those studied reported a symptom similar to drowsiness, including tiredness and fatigue. While for most people drowsiness could be a negative slide effect, for some people who struggle sleeping, this is seen as a positive side effect. Early studies have shown CBD in higher doses will assist in the sleep process while smaller doses aid in increased alertness.

Dry Mouth

Due to the face that CBD increases anandamide levels in the mouth, dry mouth is a possible side effect.

Low Blood Pressure

While there is some debate on if CBD does affect blood pressure, a 2017 study led by the University of Nottingham found it may reduce blood pressure in healthy people.

A single dose of CBD was found to reduce resting blood pressure and the blood pressure response to stress.

This can be a beneficial side effect for those at risk of heart disease or who have high blood pressure.

Lightheadedness

A reported side effect of CBD is lightheadedness. It is believed that this is simply a result of low blood pressure decreasing blood flow to the brain.
