CBD might interfere with the other medications you take. Dr. Matharu-Daley says it’s important to talk to your doctor about whether CBD could affect your existing prescriptions.

CBD benefits include the following:
CBD is one of the many chemical compounds that is found in the cannabis plant—referred to as cannabis sativa. There are two primary parts of the plant that humans use. One is THC, or Delta-9-Tetrahydrocannabinol, and the other is CBD. Though they’re from the same plant, THC and CBD are quite different from each other.
Because CBD supplements come in so many different forms—such as oils, gummies, tinctures, and vapors—the amount that’s actually absorbed can vary drastically. This, combined with each person, will ultimately affect which (if any) CBD side effects you might experience.
On the other hand, repeated CBD doses can increase the levels of some enzymes of this group and reduce the effects of the drugs they break down [71, 72, 73, 74].
And since tinctures and sprays are directly applied in the mouth, they will quickly reach the salivary glands and cause dry mouth. Mouth sprays may also cause a stinging sensation and even burns, especially if they contain alcohol [9, 78].
CBD is often used to curb anxiety, although research suggests it has “inverted U-shaped” effects: moderate doses, but not low or high amounts, may be effective for a range of anxiety disorders and stressful situations [38, 39].
Creams & Gels
If you are on prescription medication and plan to use CBD oil, ask your doctor about potential interactions and dose readjustment. Additionally, avoid combining CBD oil with grapefruit or other supplements that block the same liver enzymes (such as St John’s wort or watercress).
Avoid CBD oil if you have a weak immune system, as it might make you more prone to infection.
An advantage of CBD oil is that it’s considered generally safer and causes fewer adverse effects than the drugs typically used for these conditions. Chronic doses of up to 1500 mg/day were tolerated well in multiple studies [3+, 4].
Drinking coffee or tea will help you both stay awake and raise your blood pressure, but it also causes many side effects. Try to get more sunlight first thing in the morning, as it will energize you and help you get better sleep at night. We talk about other natural ways to increase wakefulness in this post.
Ironically, perhaps, for a cannabis product, CBD oil has been linked to loss of appetite in some people. Along with dry mouth, it can simply leave you feeling unpleasant after ingesting. As with most other side effects, this will pass in time.
According to a report by the World Health Organization, "CBD appears to have little effect on conditioned place preference or intracranial self-stimulation… [It] exhibits no effects indicative of any abuse or dependence potential."
CBD oil in all forms is regulated as a medical supplement, because this is typically how it is advertised. As a result, only five states currently have no significant restrictions on its sale and consumption. Every other state has either restricted it through marijuana laws or limits the sale of CBD oil in some form, whether through food and drink regulation, medical regulation or other forms of restriction.
Mild Side Effects of CBD Oil
CBD oil can act as a blood thinner and in doing so it can lower your blood pressure. For someone who has issues with blood pressure this can pose very real risks.
Some CBD oil salesmen promise that their product can cure everything from anxiety to cancer. They cram it into every product that can soak up a liquid, including gummies, shampoo, toothpastes and even pills for your cat. In the low-water mark for any "medical" supplement, you can now buy it at many juice bars and coffee shops as an additive that can somehow take your banana-strawberry smoothie to 11.
Advocates market CBD oil typically as a health supplement, and they do so comprehensively. It has started showing up everywhere from web banners to smoothie shops. While it has few recreational properties, CBD oil's boom in recent years is through the quasi-medical field. Like turmeric, ginseng and tinctures, CBD oil promises to ease a wide variety of ailments without the invasiveness of pharmaceutical drugs.
While doctors and researchers take CBD oil's role in medicine seriously, much of its profile has been raised by salesmen who make extravagant promises that no medicine (no less supplement) could hope to fulfill.
