Can You Take Too Much CBD Oil? Learn The Limits

It’s often been said that there’s no such thing as too much of a good thing; in reality, of course, there is. When it comes to CBD oil, more is not always best, for a few different reasons.

Depending on who you ask, your CBD’s strength, or what company you got your CBD oil from, the dosing instructions for your CBD will vary. But how much is too much? What happens when you take too much CBD oil?

Well, fortunately the answer is, not a whole lot in most cases.

CBD is one of the many cannabinoids and different compounds that makes up the hemp plant. It is the main component of CBD oil and has vast medical implications, both physically and mentally, for the human body.

Cannabinoids like CBD attach to receptors in the Endocannabinoid System. Through research, scientists have discovered that they hold anti-inflammatory, anti-oxidant, and anti-bacterial properties.

Naturally, as more people started taking CBD, the question keeps popping up – can you take too much? According to a 2011 study, they put toxic levels of CBD at around 20,000mg. To put this in perspective, you would have to consume 20 bottles of 1000mg CBD oil to hit that target. Not exactly something likely to happen.

For the average person wondering if they’ve overdone it – don’t worry, you likely haven’t. The starting dose for many CBD oils is around 5-20mg per day, with instructions to increase as necessary. There are reports of people safely consuming 1500mg per day; substantially more than most people would think of using.

What happens when you take too much CBD oil?

There are some things you might want to be aware of if you’re thinking about taking a mega-dose of your CBD. For the vast majority, they are minor.

Your risk of negative side effects goes up

Just like any medication or other supplement you take, CBD does come with some side effects. Most people will never experience anything more than an upset tummy or a mild headache; these tend to resolve once your body gets used to it.

For others, the side effects can be a little more concerning.

When you take too much CBD, your risk of experiencing any negative side effects goes up. Here’s a list of some of the side effects of CBD:

  • Headache
  • Nausea
  • Vomiting
  • Diarrhea
  • Low blood pressure
  • Drowsiness
  • Appetite changes
  • Increased anxiety
  • Dry mouth

It’s always recommended to go slow when increasing your dose to lower the chance of any side effects. When you take a whole bunch of CBD all at the same time, these side effects will increase in severity.

Your CBD actually becomes less effective at higher doses

Yes, it’s true. CBD works on a bell-curve effect. Take too little, and you’re not going to see results from it. Take too much, and it’s the same thing.

Because CBD takes some time to build up in your system before noticing anything happening, some beginners like to jump the gun and take way more than they need. In doing this, you may actually be going backward. It’s all about finding the right dose that works for you.

You’re not going to feel very good

When you take in too much CBD oil, it isn’t just the CBD that’s entering your system. Other cannabinoids, terpenes, and the carrier oil used for the tincture are going in as well.

Take MCT oil, for example, one of the most popular carrier oils for CBD. If you take too much, you’re almost guaranteed to cause yourself some pretty gnarly stomach issues for a while.

You may get very tired

One of the big things to watch out for is increased drowsiness. Many CBD users report feeling more tired even with just normal doses; taking more than usual is going to amplify this and put you more at risk in situations such as driving or operating heavy machinery.

You’ll waste your CBD

Taking more CBD than needed is a huge waste of money and product, even with the prices coming down over the past year.

Studies and user reviews put the average CBD amount needed for relief from all sorts of issues between 30-75mg a day. Of course, this isn’t one size fits all; your experience and proper dose will vary widely from the next person.

Can you overdose on CBD oil?

To date, there have been zero recorded cases of anyone, globally, overdosing on CBD oil. For obvious reasons, the amount necessary to cause a CBD overdose has yet to be put to the test in a laboratory setting, though they have reached that with monkeys.

All of the research points to CBD being a very low-risk compound that is considered very safe to take at all ages. Keeping in mind that the upper limits estimate you would need to achieve an overdose with CBD, 20,000mg; this is highly unlikely to ever occur in a normal setting with proper use.

How much CBD oil should you take?

Dosage with CBD oil is highly subjective and is based on personal health concerns, body weight, and other factors.

It’s recommended to take a low and slow approach when starting with CBD and gradually increase over time. What works for one person may not be the best option for the next, and to figure out your optimal dose, some tinkering may be required.

The dosage may also change with different conditions as well. Someone using CBD for minor inflammation may not need as much as someone using it to treat their chronic back pain.

Don’t be afraid to experiment with it and play around with different doses. Keeping a journal on your CBD usage and monitoring its effects on your body can be extremely helpful in the process.

We recommend starting out with 5-10mg of CBD twice a day, and working up from there.

Can taking too much CBD oil get you high?

CBD is a non-psychoactive compound and won’t get you high, unlike THC. THC is the cannabinoid in marijuana responsible for the mind-altering effects you get when ingesting it and is found in minimal quantities in the hemp plant.

While it’s slightly different here in Canada than other areas of the world due to the legalization of marijuana, the vast majority of other countries where CBD is legal have legal limits of THC in place for CBD oil, 0.3%. Companies here stick to this level, and it is nowhere near the amount needed to produce a high.

That being said, if you do decide to down a few bottles, you’ll be increasing the amount of THC you’re taking in; this might be enough to produce a small buzz.

CBD Overuse: Risk of Addiction?

No, you can’t become addicted to CBD, even if you take a lot of it or use it for a long time. Being a non-psychoactive compound, there are no risks involved in addiction.

Many studies have been done on the topic, and CBD has been deemed one of the few substances not to carry any major side effects or addiction risks.

In fact, new research into this area shows that CBD has the potential to aid in addiction disorders, which could, in the future, lead to new avenues of rehabilitation methods and procedures.

Closing thoughts on taking too much CBD

CBD oil has fast become one of the most popular topics of the decade. With research showing it decreases anxiety, treating chronic pain, relieving arthritis and inflammation-induced disorders, and reducing seizures, it doesn’t look like it’s going away any time soon.

Sure, you can take too much CBD, but the amounts needed to produce serious, adverse effects are almost guaranteed to never come up for you.

Feel free to play around with it, and if you start feeling any increased side effects, bump it down a notch.
