Seed Guides asserts that hemp oil can cause minor digestive system side effects such as abdominal cramping and diarrhea. Hemp oil has the ability to soften the stools.
If diarrhea is excessive due to the consumption of hemp oil, this can lead to malabsorption, according to Seed Guides. People with a history of bowel movement disorders or digestive problems should not consume hemp oil.
Hemp oil is derived from a plant that contains tetrahydrocannabinol or THC, which is a neurological chemical. THC can cause anxiety and hallucinations when used on a regular basis. Seed Guides states that some individuals are especially sensitive to THC and should be examined by their physicians to verify this.
