CBD oil has captured the attention of the press because of its many benefits to our health and wellbeing. The rise in popularity of this substance came at a time when the U.S. Drug Enforcement Administration changed the classification of cannabidiol from Schedule 1 (highest potential for abuse) to Schedule 5 (least potential for abuse). Since scientists found that this cannabinoid does not have psychoactive effects, this has been marked safe even by the WHO.

But even as CBD does not have adverse effects in the mood and thinking of a person, it can still lead to many health risks, especially if used without doctor’s supervision. Some physicians have started prescribing this cannabinoid for various health conditions.

A review, published in the Current Drug Safety journal, found that a healthy dosage of CBD has no adverse effects on the bodily functions, including heart rate, body temperature, blood pressure, gastrointestinal transit, food intake, and other psychological and psychomotor functions. This study confirmed WHO’s release that CBD hemp oil is safe even in large doses.

CBD Oil’s Potential Side Effects

However, in a review published in the Cannabis and Cannabinoid Research journal in 2017 provided a balanced view of both the safety and side effects of CBD. The paper found that the most typical side effects of using this cannabinoid are tiredness, diarrhea, and change in appetite.

Aside from the ones mentioned above, some studies indicated that the conditions from using cannabidiol:

  • Anxiety
  • Changes in appetite
  • Changes in mood
  • Drowsiness
  • Nausea and dizziness
  • Vomiting

Effects on Pregnant Women and Nursing Mothers

Exposure of pregnant women and breastfeeding mothers to any substance from marijuana can result in an adverse impact on the development of their baby, warned an American Academy of Pediatrics report found within the Pediatrics journal. Even brief exposure to CBD may make the placental barrier more permeable, which can put the fetus at risk of getting contact with certain substances.

Side Effects in Movement Disorders

CBD can also lead to some side effects when administered to patients with dystonic movement disorders. A study published in the International Journal of Neuroscience in 2009 found that a daily 100–600mg oral dosage of the cannabidiol led to side effects such as low blood pressure, reduction in psychomotor activities, lightheadedness, sedation, and dry mouth.

Researchers observed increased hypokinesia and resting tremor for more than 300mg of daily dosage. This study concluded that cannabidiol can aggravate Parkinsonism in humans.

Interaction with Prescription Medicines

Another study found that cannabidiol can have a damaging effect on drug metabolism inside the liver. This finding is particularly crucial for those taking medications. Based on some studies, cannabidiol can interact with drug-metabolizing enzymes especially those belonging to the cytochrome P450 family. Approximately 60% of all drugs that you can buy in pharmacies are metabolized by this enzyme type, which is also responsible for breaking down CBD.

So, if you’re taking prescription medicines you should consult with your doctor before using this cannabinoid. But, these interactions may only be a minor issue. In fact, cannabidiol can provide beneficial actions on your liver enzymes. It can boost the levels of CYP1A1 enzyme, which can break down harmful substances like benzopyrene. Other research revealed cannabidiol oil’s interaction with some medications for epilepsy.

May Contain THC

Some CBD oil brands contain some THC, another substance from cannabis that may reduce your ability to drive with caution or operate equipment. Some people with high sensitivity to THC can also impair their attention, memory, mood, and mental health.

While CBD oil is packed with benefits for your health, it can also harm your health. To ensure your safety in taking any CBD products, you should consult your doctor regularly.
