Can you take too much CBD? The answer might surprise you. 

CBD is found in everything from mints to skincare to pet products. We scroll past bloggers that rave about its benefits online and walk past CBD products on the aisles of our local CVS Walgreens. But, without the FDA monitoring the production of the famous cannabinoid, how safe is it?

Here, we’re going to cut through the jargon and give you the facts you need to know about cannabidiol or CBD, the “healing” compound found in cannabis. 

Can you overdose on CBD?

If you’re considering the health benefits of or have already started taking CBD, you may wonder, “Can you take too much CBD?” and “Can you overdose on CBD oil?” 

Most people are glad to learn that CBD is widely considered safe in low to moderate doses. Even CBD taken at very high doses is not likely to result in an overdose.

But all chemical substances have a fatal cutoff point somewhere. Even water can be fatal to humans if we consume too much in a short period. 

Although there are no specific studies on the toxic levels of CBD in humans, data from the Toxicology Data Network suggests that a 40 lb dog would need to consume over 4,600 mg of CBD in a single dose to reach a level of toxicity. 

However, a 2011 article published in Current Drug Safety suggests that problematic levels of consumption are even higher, exceeding 300 mg of CBD per 2 lbs of body weight in rhesus monkeys.  

That said, it would take an enormous amount of CBD to trigger an overdose in humans. Our tolerance is much higher because we weigh much more than a dog or a rhesus monkey. 

So, how much is “too” much CBD for humans? Keep reading to find out. 

How much is “too” much CBD for humans? 

If you’re wondering if you can take too much CBD, the short answer is: Yes, but it’s a lot

There aren’t any studies on the toxic levels of CBD in humans, for obvious ethical reasons. However, the 2011 article by Current Drug Safety mentioned above cites that a “toxic dose” of CBD for humans lands around 20,000 mg of CBD – taken all at once. 

To put it in perspective, it’s important to note that the recommended starting dose of CBD is around 5-20 mg per day and go up to as much as 1500 mg per day. Meanwhile, most CBD tinctures hold 100 to 1500 mg in an entire bottle. 

That means that someone would have to drink over 13 bottles of CBD in a short period before they need to be concerned. That’s a lot of CBD! 

Of course, no one should set out to “test” the toxic dose of CBD or the “side effects CBD.” However, new users should feel safe to find a treatment that is effective for their unique needs with little ‘CBD negative effects.’ 

What are the side effects of CBD?

CBD might not kill you, but take too much, and you may experience CBD oil side effects. 

According to the World Health Organization, “CBD is generally well-tolerated with a good safety profile.” Additionally, CBD is one of the only substances with a low risk of dependency and no significant side effects. To date, there is no evidence of CBD’s recreational use or any public health-related problems associated with the use of pure CBD.

But, like any other drug, CBD may cause uncomfortable side effects in substantial doses. 

CBD users have a lot of questions like; What are the side effects of CBD hemp oil? Does CBD make you lightheaded? Can CBD oil make you dizzy? 

Here’s what you need to know:

  • CBD oil side effects and hemp oil side effects range from diarrhea, disorientation, drowsiness, lethargy, nausea, upset stomach, but not death (whew!)
  • Other negative effects of CBD include CBD dry mouth and dizziness. High doses of CBD may cause a small drop in blood pressure, which is often associated with these ‘side effects CBD oil.’ 
  • CBD can also interact with other medications you’re taking, such as blood thinners.

Essentially, the average person doesn’t have to worry about CBD overdose or CBD oil overdose. But there could be some unfavorable CBD side effects if you overdo it. 

That said, you should always speak with a doctor before adding CBD into your self-care routine. CBD may affect certain medications. It is important to note that these products have not been approved by the FDA to diagnose, treat or cure any disease. Furthermore, the FDA does not recommend CBD for pregnant or breastfeeding women. 

Tylenol vs. CBD side effects

Lets compare with the Side effects of acetaminophen (Tylenol)

According to rxlists.com: (https://www.rxlist.com/tylenol-side-effects-drug-center.htm)

“Side effects of Tylenol include:

• nausea, stomach pain, loss of appetite, itching, rash, headache, dark urine, clay-colored stools, or jaundice (yellowing of skin or eyes).

Get medical help right away if you notice symptoms of a rare serious allergic reaction to Tylenol, including:

• rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.”

Another list of acetaminophen side effects from drugwatch.com: (https://www.drugwatch.com/tylenol/side-effects/

“Tylenol Side Effects

Tylenol (acetaminophen) is a popular pain reliever and fever reducer found in many prescription and over-the-counter (OTC) medications. It’s generally considered safe when taken as directed. But taking large doses of the medication or combining it with alcohol can cause stomach cramps and nausea before the rapid onset of acute liver toxicity and liver failure. In rare instances, the drug can cause serious, and sometimes fatal, skin reactions.”

Side effects for ibuprofen have similar side-effects lists, and prescription pain medications have even more extensive lists of side effects.

When we compare what we understand about the side effects of CBD with OTC pain relievers,  it seems a CBD is a natural alternative that is well tolerated. 

Final Thoughts: Can you take too much CBD?

The question remains, “Can you take too much CBD?” 

You can, but you’d have to ingest an abnormally large amount before it is a concern. 

To clarify, there is no precise lethal dose of CBD in human beings. Unlike other substances, CBD is not widely considered fatal for the average user. 

The cannabidiol compound is generally safe and non-addictive – as highlighted by WHO and other organizations. Plus, it can have profound therapeutic effects on a variety of conditions.
