Can You Overdose CBD Vape Oil?

CBD vaping is relatively safe. It is one of the good ways to quit smoking and alcohol. Even CBD is Healthier Than Alcohol. It has many other health effects, like reduced stress, anxiety, pain, and enhanced sleep. People rarely experience any side effects of CBD. However, one should use CBD vapes responsibly. So, can you overdose on CBD vape oil?

Well, in short, “Yes”, that is possible. However, in practice, chances are slim. The chances of overdosing on CBD vape oil are extremely low.

For example, one may readily overdose CBD oil for sub-lingual use by ingesting larger amounts or even ingesting it accidentally.

However, overdosing on CBD vape accidentally is almost not possible. It is only possible if done intentionally by taking too many puffs. Even in that case, one would need lots of time. On the other hand, CBD vape oil has higher bioavailability and, thus, the risk of overdosing.

What Happens When You Vape Too Much?

Vaping too much CBD vape oil can have various effects on the body, some of which can be undesirable. While CBD vaping is generally considered a safer alternative to traditional smoking, excessive CBD vaping can lead to specific consequences:

  • CBD Overload: If your CBD vape oil has a high concentration of cannabidiol, overvaping can lead to CBD overload. This can result in symptoms like drowsiness, lethargy, and an overall feeling of excessive relaxation.
  • Dry Mouth and Throat Irritation: Frequent CBD vaping can dry out the mouth and throat, leading to discomfort, soreness, and a persistent cough.
  • Impact on Respiratory Health: Excessive CBD vaping may have adverse effects on lung health, potentially leading to symptoms like shortness of breath and chest discomfort.
  • Reduced Effectiveness: Over time, the body may develop a tolerance to CBD, requiring more frequent or stronger hits to achieve the desired effects.
  • Financial Costs: Regular CBD vaping can be costly, with expenses adding up over time, affecting your budget.

To avoid these effects of CBD vaping, it’s essential to vape CBD in moderation, be mindful of the concentration of CBD in vape products, and pay attention to your body’s signals.

If you experience adverse effects from vaping CBD, it’s advisable to reduce your vaping frequency or consult with a healthcare professional for guidance. Responsible and moderate CBD vaping can help mitigate these potential consequences while maximising the benefits of CBD.

How Much of CBD is Too Much?

Nothing in excess is good, and CBD is no exception. CBD is not dangerous for health, but excessive intake can be bad for health. CBD is the most extensively tested of all the cannabinoids. It means that its short and long-term safety is more or less established. In fact, some CBD-based drugs are already approved for use in medical conditions.

All this means that much research has been going on in the last few decades regarding CBD’s health effects and dosage. Therefore, researchers now know CBD dosage that is safe for use by most people and does not cause any ill effects.

Hence, the Food and Standards Agency (FSA) of the UK states that people must avoid ingesting more than 10 mg of CBD a day. These are the latest and updated recommendations as of October 2023[1]

Remember that these are recommendations for those who plan to ingest or vape CBD daily and not for casual vapers or consumers.

So, how much is 10 mg in terms of CBD vaping? Well, if we look at different disposable CBD vape pens, we see that smaller vape pens contain 500 mg in 600 puffs, and larger ones contain 2000 mg in 3000 puffs. It means that 10-15 puffs a day would provide a dose of about 10 mg.

However, considering that even CBD vapes do not have 100% bioavailability, it would be safe to say that 40-60 puffs a day are within the FSA’s recommended limits of CBD dosage.

However, one should understand that what FSA recommends is something that is safe for most people and is not likely to cause even mild side effects. It means that to overdose on CBD vape oil, a person would need to intake CBD at much higher dosages (a few hundred puffs), perhaps multiple times higher than what FSA recommends as optimal dosage.

Keeping in mind all the above information, it would be safe to say that one would need to vape a lot to overdose on CBD vape oil. In practice, chances are slim that someone can do that accidentally, though one can do it intentionally.

The Bottom Line

CBD is among the safest and most extensively tested cannabinoids. It is among the major cannabinoids in the cannabis or hemp plant. It is now well-proven to have numerous health effects and is safe for prolonged use by humans. Nonetheless, due to individual differences, little is known about its optimal dosage. However, FSA recommends not to exceed CBD’s daily dose of 10 mg if taking regularly. 

Our experience shows that exceeding FSA’s recommended dosage is only possible by inhaling more than 40 puffs daily. Even then, it would not essentially result in overdosing, as the FSA’s recommendation is about optimal dosage. So, in practice, chances are slim that someone can overdose on CBD vape oil.
