Delta 8 THC Side Effects List

Research regarding this topic is unfortunately lacking at the moment due to the simple fact that delta-8 is new to the scene, and so we don’t have any concrete research as of now.  But these are the Delta 8 THC side effects that are possible according to what those who use delta 8 have shared. This includes Delta 8 THC vape cartridges side effects, delta 8 gummies, delta 8 capsules, and other Delta 8 THC products. Let’s get into it!

#1: Anxiety (When Taking Too Much)

We said that delta 8 seems to have anti-anxiety properties but taking too much could create a paradoxical effect.  This is related to the psychoactive properties of the compound, which some may be more sensitive to than others.  Anything that creates mind-altering effects could make some people feel uncomfortable, especially in larger doses.  This is why it’s always ideal to go slow, starting with a very small dose until you feel comfortable with how this cannabinoid works in the body.

#2: Dry Mouth

Delta8 could cause temporary dry mouth, for as long as the compound is active in the body.  This is why you may wish to increase your water intake.  Note that the dry mouth is not a sign of bodily dehydration but is the result of effects on the salivary glands.

#3: Dry Eyes

Dry eyes are another potential side effect of delta 8, again being temporary and lasting only as long as the cannabinoid is active in the body.  This can leave the eyes looking red, and in rarer cases cause discomfort due to the lack of moisture.  Moisturizing eye drops can remedy this side effect in most cases.

#4: Grogginess

Some people find that higher doses of delta 8 THC make them feel temporarily groggy, and some people feel a strong urge to take a nap.  The grogginess can be accompanied by brain fog, fatigue, mild lightheadedness, and poor concentration.  This is a side effect that typically goes away once the delta 8 has worn off and is less likely to occur if you take a smaller dose.

#5: Getting Too Much of a Body High

THC causes two types of highs simultaneously: a mind high and a body high.  Delta 8 THC is known for being the cannabinoid that causes intense body highs. High doses of delta 8 can cause the body high to become stronger than some people would like. 

This could mean difficulty moving, known as “couch lock,” an over-awareness of sensations in the body that can lead to anxiety, and temporary feelings of numbness, twitching and cold/warm sensations.  Sometimes, a person can feel as though their heart is pounding despite no known negative effects on the cardiovascular system. Luckily, because of the way Delta 8 works, it is not known for giving anxiety or intense heart pounding like Delta 9 THC. For Delta 9 THC vs Delta 8 THC click here

#6: Getting Too Much of a Mind High

Because delta 8 is psychoactive, some people might consider getting too high a side effect.  First, one can get too much of a mind high, which means that the cerebral properties of the compound can make a person feel too much “in their head” or simply out of it. 

While many people purposely use THC because of its cerebral effects, sometimes taking too much can alter one’s state of consciousness so much that it interferes with their ability to have cohesive thoughts, stay on track and be aware of their surroundings.

#7: Being Unable to Drive

When you take too much delta 8, it can impair your ability to drive.  This is why you should never drive when you are intoxicated by THC.  It’s possible that driving under the influence of delta 8 can be dangerous. Therefore, take Delta 8 THC in safe conditions where you are not driving, or have other responsibilities that may be impaired or safety is at risk of. Like alcohol and regular Delta 9 THC, the responsibilities when taking Delta 8 is not any different.

#8: Work Interference

Using delta 8 before or during work hours can interfere with your ability to do your job.  This is due to its temporary effects on both cognition, physical coordination, and physical abilities. Therefore, it is best to use this compound when you are off working hours or low risk situations. 

#9: A Failed Drug Test

Delta-8 THC can cause you to fail a drug test due to the fact that it triggers the same metabolite that breaks down delta-9 THC in marijuana, which is what urine tests are looking for. Even though Delta 8 THC is different than Delta 9, because it is still a THC it will trigger a drug test. Drug tests look for all versions of THC. 

#10: Unpredictability

Delta 8 THC creates a type of high that can “sneak up on you,” which can catch people off guard.  This is why you should always make sure that you don’t have any important responsibilities prior to using it. Additionally, this almost means you should take the appropriate wait times depending on your method of usage

#11: Feeling Too Happy

We had to do it. Delta 8 THC is known as an amazing compounds that provides minor psychoactive effects and many benefits including being happy, with usually less side effects than regular Delta 9 THC. Now, there’s no such thing as “feeling too happy”, but we have to say that the most known effect of taking delta 8 is feeling euphoric and giggly.  Also, that’s not such a bad side effect, is it?

How to Avoid the Potential Side Effects of Delta 8 THC

If you’re worried about the potential side effects of delta 8, the best way to avoid them is to simply not take too much at one time.  Side effects mentioned earlier are more likely to occur if you take more than the recommended dosage amount.

One issue we have noticed is many customers underestimate the power of Delta 8 THC, because it is 50-70% of the high you would receive from Delta 9 THC. Therefore, they think it will not be potent or affect them much. In consequence, they end up taking much more than the recommended Delta 8 THC dosage. We always suggest taking 1-3 hits of a vape cartridge and see how you feel within 30 minutes. Or for edibles, wait over an hour to see how it effects you. 

We also recommend choosing a less potent delivery method. Vaping, smoking, and even dabbing delta-8 can produce the strongest effects, so if you’re trying to avoid a product that’s too strong, opt for something more subtle such as a capsule or an edible.

Delta 8 THC May Come with the Possibility of Some Side-Effects

As you can see, none of delta8’s side-effects are major, and they all last for only as long as the compound is producing a high in the body. The worst cases we see, usually end up resolving by the next day. Many find that the experience of a delta8 high is very enjoyable, with generally less overall side effects than regular Delta 9 THC. Additionally, even these potential side effects usually do not cause any kind of intense long-term distress. 

Of course, everyone is different when it comes to how THC affects them, so be mindful of how you feel and note any side effects that may occur. Remember that ultimately, delta 8 THC is a nontoxic compound that the human system can manage even in high doses, so none of the side effects that delta-8 could potentially cause are linked to severe or life-threatening symptoms.
