The takeaway about CBD is that the initial research is promising but there is still much to learn. It may help with some conditions like long-term pain and sleep.
Early research on CBD for the treatment of insomnia suggests that it may be effective. Additional studies are needed.
Marijuana contains more THC than CBD. Hemp has a very small amount of THC, less than 0.3 percent, and not enough to cause a high. As of 2018, CBD from hemp became legal in the U.S.
Does Oral CBD Help with Sleep?
CAUTION: Since CBD may cause tiredness or drowsiness, people should be very careful when driving, using tools or other equipment, or performing other risky activities.
Already tried CBD? There are many other ways to reduce back pain or insomnia that do not involve taking it. Learn about some other methods that Goodpath's integrative medicine approach uses to reduce your symptoms here:
Topical cannabidiol oil was studied in 29 people with lower limb peripheral neuropathy. After using the oil for 4 weeks, the people had less intense and sharp pain and fewer other uncomfortable sensations.
The dose of CBD also depends on the form and strength and whether or not it has other active ingredients.
CBD is well-known to offer benefits to specific health conditions. There’s a lot of research on how this compound offers benefits towards diseases such as epilepsy, multiple sclerosis, cancer, arthritis, and more — however, some people may experience a worsening of symptoms after using CBD for their health disorder.
In this article, we’ll cover the potential side effects of CBD in detail — including both the long-term and short-term side effects.
How To Minimize Your Risk
This is true for both the positive and negative effects of CBD. Several of the research papers cited above used large doses of CBD (up to 20 mg/kg), which is significantly higher than the standard dose of CBD. However, despite remaining safe at these doses, the larger the dosage of CBD, the more chances there will be side effects.
Contaminated CBD products aren’t uncommon, so it’s important you look for a reputable supplier before placing your order. CBD oils that are significantly cheaper than the competition are most likely too good to be true. Many of these oils are made from cheap hemp cultivated in places like China or India where soil contamination is common — leading to the accumulation of heavy metals or other harmful compounds in the final product.
There are a few CBD-based pharmaceutical preparations on the market, such as Epidolex and Sativex — each of which has had a ton of research done to assess the potential for side effects. This research has given us a lot more insight into the potential adverse effects of CBD and other related cannabinoids.
Although CBD might be a new molecule to you, scientists have been studying it since the 1970’s, alongside its infamous sister molecule, THC. For the past few decades, lawyers, doctors, patients and politicians have all been pitting the medical potential of cannabis against its risk for recreational abuse. But all the while, evidence has been mounting that CBD offers similar — if not better — medical benefits without the downside of a “high” from THC.

Clinical evidence for CBD oil
Even a critical review by the World Health Organization (WHO) recently reported that CBD is a promising treatment for a number of medical conditions, is well tolerated, has a good safety profile, and doesn’t appear to be a risk for abuse, dependence, or other public-health related problems. In other words, even the WHO thinks CBD is A-OK.
You’re immune compromised. (Most evidence disproves this concern) CBD is known as an immunomodulator because it can calm down a hyperactive immune system , but some worry this could harm people whose immune systems are already impaired, like HIV sufferers. Although we don’t have evidence specifically testing CBD against this fear, many studies have been done using the whole cannabis plant. Research shows that cannabis helps relieve pain and other HIV-related symptoms without causing severe side effects . And when marijuana is tested against specific HIV symptoms like liver fibrosis, cannabinoids do not appear to worsen it . Although current evidence suggests that CBD could be more helpful than harmful for immune-compromised individuals, the jury is still out.
