Another important component, CBD (cannabidiol, which works by increasing natural cannabinoid levels in the brain) is associated with the calming, anti-anxiety effects of the drug. In addition, CBD is thought to protect against many of the potential negative effects of marijuana, including dependence, psychotic symptoms and cognitive impairments.
The THC concentration in cannabis has increased by as much as 12% over the past 30 years, making the drug much stronger than it used to be. At the same time, there has been a significant depletion of CBD, sometimes to levels as low as 0.1%. “Skunk”, as this new strain of high-THC/low-CBD marijuana is called, is flooding the illegal marijuana market, and it is this variety that is thought to be behind the rise in cannabis dependence diagnoses, links to schizophrenia, and cognitive deficits seen over the past decade.
Reports of memory loss with long-term cannabis use are nothing new, and an influential paper published last year provided evidence that smoking marijuana has a deleterious effect on intelligence. In the investigation, the cognitive abilities of participants were tested several times over the course of 25 years. The researchers found that heavy cannabis users had significant decreases in intelligence and memory ability as they aged, not only compared with non-smokers, but also compared with their younger selves. Additionally, the earlier they started smoking pot, the bigger the cognitive decline.
The recent legalisation of recreational and medicinal marijuana in parts of the US has the potential to reduce significantly the harms caused through incarceration or criminal records for minor drug-related offences. However, it also provides an opportunity to reduce the cognitive and psychiatric harms linked to cannabis use. With this shift in drug policy, it is now possible for states to monitor the commercial production of cannabis, regulating the levels of THC and CBD present in the drug. To facilitate this, they could force growers to use strains with higher levels of CBD, and revert to more old-fashioned farming methods that don’t use round-the-clock lighting.
Obviously these findings are worrying, especially given the recent spate of cannabis legalisations in states across the US and in countries such as Uruguay. However, before we all start worrying about the good people of Colorado and Washington, it might be helpful to look closer at what’s actually in the cannabis we’re smoking nowadays, and what ingredients are contributing to these cognitive deficits.
It should be noted that the majority of research into cognitive deficits and cannabis use has focused on heavy or dependent users, and there’s little evidence that occasional smokers show any of the problems mentioned above. But with the recent changes in drug policy, the chances are that more people will be smoking cannabis than ever before, and the more potent and more popular high-THC/low-CBD marijuana that is available today will increase their risk of dependence.
THC (tetrahydrocannabinol) is the primary psychoactive compound in cannabis and is what causes the subjective “high”. This includes changes in perceptual sensations, a feeling of contentedness and increased appetite. However, THC is also linked to many of the potential negative consequences of cannabis use, such as dependence, psychotic symptoms, and impaired memory and cognition.
Different studies recommend starting with 1–50 mg of CBD daily. While 1 mg is rather considered a microdose, most people start with 5–10 mg twice a day. For some people, CBD may provide fast relief, whereas others will need to give it some time to work in the endocannabinoid system. Still, if you don’t feel any difference after a week of testing your dose, increase it by another 5 mg, and monitor the results for next week.
Memory loss triggered by degenerative conditions, such as dementia and Alzheimer’s disease, is a significant area that CBD oil has been shown to alleviate inflammation of the brain, reduce oxidative stress, and improve the regeneration of neurons, all of which can help improve cognitive performance.

How Much CBD Should I Take?
Today, we’re going to cover CBD’s potential in fighting Cognitive Decline (CD), the scientific term used to diagnose memory loss. The condition is more likely to occur with aging; that’s why learning more about CBD, including its effects on catabolic processes in the brain, is essential to understand how it can help with memory issues.
In recent years, CBD has been found to alleviate certain symptoms of memory loss conditions, including different types of dementia. People are turning to CBD oil to treat Alzheimer’s disease as well as to improve focus and enhance the daily performance of their brains.
Once you’ve found the amount of CBD that boosts your focus and memory, you can stick to it, as people don’t build a tolerance to CBD. The cannabinoid is even known to induce “reverse tolerance,” where users take less CBD over time due to feeling better.
In a review published in the Journal of Pediatric Pharmacology and Therapeutics, the authors reported that CBD oil had been shown to support people with a range of medical conditions, including the behavioral symptoms of ADHD, such as a short attention span (5). Another study mentions anxiolytic (anti-anxiety) and sleep-regulating properties of CBD, both of which contribute to better memory retention (6).
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.

The bottom line on cannabidiol
Cannabidiol (CBD) has been recently covered in the media, and you may have even seen it as an add-in booster to your post-workout smoothie or morning coffee. What exactly is CBD? Why is it suddenly so popular?
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a "high." According to a report from the World Health Organization, "In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD."
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So, you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
