CBD and THC mixed together create magic, proven by scientific studies. however, when CBD is mixed in, many users experience relaxation and It's important to note that the same strain may affect users in different ways. In fact, many patients report an alerting effect from CBD and thus care should be many patients would normally experience from the THC present. MEDICAL CANNABIS USE IN POST-TRAUMATIC STRESS DISORDER. The recreational use of cannabis can have persistent adverse effects that are experienced during recreational cannabis use. . When CBD and THC were administered together, the anxiogenic effect of THC was halved.

If you keep seeing this age prompt whenever you visit Leafly. CBD ratio will strongly affect your experience. Strain effects will also depend on the presence of other compounds, like terpenes. CBD ratio is a huge factor in how a strain will affect you. Can we anticipate any general effects from the THC: When people take pure CBD, even at very high doses, it is well tolerated and produces no obvious intoxicating effects. Cannabis connoisseurs will be well aware of the general differences between the effects of THC-dominant vs.
Novice cannabis consumers, by contrast, should start by understanding the basic differences between balanced vs. THC-dominant strains before worrying about further subtleties or experimenting with the more potent cannabis products. Balanced strains like Harlequin or Cannatonic will still get you high, but your experience will be noticeably different compared to THC-dominant strains.
Based on what we know from scientific studies, the effects of balanced strains may differ from THC-dominant strains in the ways listed below. The presence or absence of other compounds will likely influence the effects of specific strains and products.
The list below should be viewed as a basic introduction to plausible differences between balanced and THC-dominant strains. It should not be considered a definitive guide to how every single strain will affect you. Studies in both humans and animals indicate that CBD can have anti-anxiety effects. Studies in humans have observed that CBD can diminish the anxiety provoked by a stressful situation like public speaking or the paranoia and cognitive impairment provoked by THC administration.
Laboratory studies in animals also generally find that CBD reduces behavioral measures of anxiety. There seem to be two important reasons for this. For some people, this includes anxiety or paranoia especially with high doses of THC. Second, CBD can exert direct anti-anxiety effects through its influence on other receptor systems in the brain. The serotonin system is a common target of some prescription drugs commonly used to treat anxiety.
A hallmark of the THC-induced high, especially at higher doses, is short-term memory impairment. For example, a study examined the effects of smoked cannabis on memory. Intriguingly, this study assessed regular cannabis consumers and allowed them to ingest their own cannabis. On average, the THC content was similar in both groups, but the cannabis consumed by those smoking balanced strains also contained CBD. Consumption of only THC resulted in memory impairments, as expected. Some may be diminished while some are not.
The specific effects will depend on the precise THC: CBD ratio, method of consumption , and presence of other compounds, such as terpenes. It is well established that THC can have sedative effects, and small studies in humans have found that CBD can counteract them. Animal studies are generally consistent with these findings: Both human and animal studies indicate that pure CBD, given alone or in combination with pure THC, has anti-sedative effects at low-to-moderate doses.
Small human studies where people have been given very large doses of pure CBD have been mixed, with some finding sedative effects and others finding no effects on wakefulness. Skip to main content.

Endocannabinoids are lipid-soluble compounds, which prevent them from traveling long distances within the brain. As a consequence of this feature, endocannabinoids are ideally suited for small-scale, local physiological processes Tetrahydrocannabinol mimics the effect of endocannabinoids. In contrast to these substances, THC is not rapidly broken down at the site of operation, and it not only works at specific locations but simultaneously activates all CB receptors throughout the brain The mechanisms by which CBD exerts its effect are not precisely known, but it is clear that the pharmacological actions of CBD follow from many different mechanisms [for reviews, see Ref.
By inhibiting the degradation of the endogenous cannabinoid anandamide, CBD intensifies, and prolongs its effect Through its effect on intracellular calcium concentrations, CBD might protect neurons against the possible neurotoxic effects of THC CBD itself has almost no effect on normal physiological processes.
In many of these studies, the doses that have been used are not relevant to the situation typically encountered by recreational cannabis users. Clinical research has focused on the physical effects of cannabis use, such as pain relief, appetite promotion, and inflammation. In many experimental studies, the routes of administration used for both THC and CBD are not comparable to the routes of administration found in recreational cannabis use.
The high dosages of CBD that have been used in experimental studies increase the concentration of CBD in the blood to levels that can never be reached by smoking a joint.
The method that is most comparable to smoking is exposure through a vaporizer, but little research has been conducted involving the administration of cannabis, THC, or CBD via a vaporizer 24 , Therefore, it is unknown to what extent the effects of a single administration procedure can be extrapolated to recreational cannabis users given such differences in usage patterns.
Research on the pharmacological and toxicological properties of CBD has been performed on different types of animals. In general, the metabolism of CBD in different species seems similar to that observed in humans, but some differences exist It is possible that differences in metabolism and kinetics among different species have been responsible for some of the observed differences in pharmacological and toxicological effects. Little research has focused on the safety and side effects of CBD in humans.
However, several studies have described the effects of CBD for therapeutic applications in clinical trials. Only a few, generally mild side effects have been observed after administration of CBD in these human studies, though a wide range of effects over a wide dose range, including acute and chronic administration, have been examined. Few undesirable effects are reported, and tolerance for CBD does not seem to occur.
Based on an extensive literature review, Bergamaschi and colleagues concluded that CBD, to the extent that it has been studied, is a substance with low toxicity Notably, however, the absence of harmful effects of CBD in humans has been described in research that was not primarily aimed at investigating these same side effects or toxicities of CBD.
Because no specific research on these issues has been performed, it is currently impossible to draw conclusions about differences in toxicity between hashish and marijuana. Chronic cannabis use is associated with psychiatric toxicity and cannabis has been implicated in the etiology of long-term psychiatric conditions Several in vivo brain scanning techniques have been conducted to investigate whether chronic, heavy cannabis use leads to structural changes in the brain [for reviews, see Ref.
The results of these studies have been relatively inconsistent. In general, no differences in total brain volume between cannabis users and non-users have been found.
With respect to CB1 receptor concentrations in different parts of the brain, it can be expected that structural changes after chronic intensive cannabis use would most likely eventually be situated in the orbitofrontal cortex OCC , the anterior cingulate cortex ACC , the striatum, the amygdala, and the hippocampus 31 — In some structural magnetic resonance imaging sMRI studies, reductions in the volumes of the hippocampus, the amygdala, and the cerebellum have been found in adult heavy cannabis users when compared with healthy controls 21 , 34 , Using a PET scan technique, Wilson and colleagues found age-dependent morphological changes in early-onset cannabis users.
In subjects who started their cannabis use before the age of 17, it has been found that the ratio of cortical gray to white matter is smaller when compared with subjects who had started using cannabis after their 17th birthdays Structural abnormalities due to chronic cannabis use have been most consistently identified in the hippocampus 21 , 34 , Using a voxel-based morphometry VBM approach, Demirakca and colleagues studied gray matter GM concentrations and volumes of the hippocampus in 11 chronic recreational cannabis users and 13 healthy controls and correlated their findings with THC and CBD measurements made from hair analyses.
They found that cannabis users showed lower GM volume in the right anterior hippocampus. The conflicting results among volumetric brain studies seem to result from differences in time span e. The effects of cannabis on psychological functioning mainly concern psychotic symptoms, anxiety, depression, cognitive functioning, and the potential for abuse and dependency. These effects are dose-related i. They suggested that the high incidence of cannabis-related psychosis among their patients occurred because cannabis variants in South Africa are more potent in terms of THC content and because they lack CBD As early as , there were indications that the psychosis- and anxiety-inducing effects of THC can be suppressed by CBD 41 , Several other studies have found support for the antipsychotic effects of CBD.
The striatum plays an important role in planning activities, modulating motor activity movement , and performing cognitive tasks.
CBD has been found to increase the activity in this brain area Moreover, in other brain areas, the effects of CBD on neurological activity have been shown to be opposite those of THC. In one Dutch and three English studies, associations between the consumption of certain types of cannabis and the occurrence of psychotic symptoms were reported 41 — Longitudinal studies that have investigated the relationship between chronic cannabis use and the occurrence of psychosis have shown that cannabis use increases the risk of later psychotic symptoms and disorders by a factor of 2—3.
One case-control study has shown an association between the occurrence of a first psychotic episode and the use of high-potency cannabis skunk or sinsemilla Patients with psychotic symptoms had more frequently used skunk or sinsemilla cannabis instead of hashish than had non-patients.
Patients experiencing first-episode psychosis were also more likely to be daily users of high-potency cannabis than were controls. This finding suggests that both the daily use and consumption of cannabis with a high-THC and low-CBD content increase the risk of developing psychosis. Cannabis use can lower the age of a first psychotic episode 53 , Epidemiological and clinical studies suggest an adverse effect of cannabis use on the course of the disease in terms of relapse, exacerbation of symptoms and number of hospitalizations 38 , 55 — With the exception of a study by Di Forti et al.
The extent to which the presence or absence of CBD in cannabis will influence the early occurrence of a first-episode psychosis or to what extent it will affect the course of the disease is, therefore, unknown. Anxiety and panic attacks are the most commonly reported adverse reactions following the use of cannabis. Inexperience and use in a foreign environment play a major role Though anxiety and panic attacks are often reported, many users take cannabis for its fear-inhibiting effects [for a review, see Ref.
THC seems to be responsible for the anxiogenic effects of cannabis [e. By the early s, it had been shown that THC led to a significant increase of acute anxiety symptoms, while CBD had no effect The results from later studies, however, were inconsistent; the anxiety-reducing effect of CBD was not found in all subsequent studies.
Ilan and colleagues investigated the contribution of THC and CBD to the subjective and behavioral effects of smoked marijuana In their study, 23 healthy marijuana users were randomly assigned to a low- or a high-THC group and low or high levels of CBD.
In the four sessions under blinded conditions, subjects smoked marijuana cigarettes containing placebo no active cannabinoids or cigarettes containing THC with low or high levels of CBD. Compared with the placebo, cannabis caused a slight short-term increase in anxiety symptoms VAS.
These effects were greatest in the high-THC condition and appeared to diminish when the CBD content was high, but this latter effect was not statistically significant. Because this increase in anxiety was generally mild and because not all subjects responded with fear, a follow-up analysis with only the anxious subjects was performed.
There was a non-significant trend for less anxiety in the high- versus the low-CBD condition in subjects who reported higher levels of anxiety after smoking the joints. A reason for the absence of significant results in this study might be that neither the THC nor the CBD concentrations were high enough to have significant effects.
In the studies in which anxiety-reducing effects were reported, high oral doses of CBD typically were involved. Cannabis that is used for recreational purposes does not contain such high amounts of CBD. People with cannabis dependence are more likely to suffer from an anxiety disorder and, in particular, from social anxiety disorder [for a review, see Ref. So far, studies investigating the relationship between cannabis dependence and anxiety disorders have not clarified the nature of the relationship in question: In two experiments using patients suffering from social anxiety disorder along with healthy volunteers as controls, the subjects had to speak in front of a video camera, regardless of whether they were under the influence of CBD.
In this experimental situation, CBD was effective in preventing symptoms of anxiety, both in healthy volunteers and in patients with social anxiety disorder 41 , CBD suppressed the symptoms of anxiety, similar to the action of the sedatives diazepam and ipsapirone. Overview of studies investigating the effect of cannabidiol or cannabidiol in combination with THC on psychological functions in humans. Studies in which cannabis extracts have been used are not included.
Several studies have shown that cannabis and THC dose-dependently cause cognitive and psychomotor function impairments along with memory, selective attention, locomotion, perception, and response impairments 83 — Little experimental research exists on the effects of CBD alone or in conjunction with THC on cognitive and psychomotor functions. Morgan and colleagues identified a few such effects on memory functions, but the research on this aspect of CBD has inconsistent findings 45 , Although no human studies have specifically investigated the long-term effects of the combined effect of THC and CBD on cognitive functioning, there are indications that CBD may have some neuroprotective properties.
Much weaker attentional bias for cannabis-related stimuli was found for users of cannabis with a high CBD content than for users of cannabis with a low-CBD content. The researchers concluded that cannabis with a high CBD content confers less risk for developing an addiction than cannabis with a low-CBD content Whether smoking hashish in practice diminishes addiction risk in comparison with smoking highly potent marijuana should be further investigated.
Many recreational users of cannabis will never be faced with serious or permanent health deficits. However, for some users, the use of cannabis may cause undesirable psychological side effects, such as cognitive impairment, anxiety and paranoia, and an increased risk of developing chronic psychosis and addiction.
Despite all of the publicity surrounding cannabis, remarkably few studies have been performed that examined the relationship between a possibly harmful effect of THC and a possibly protective effect of CBD.
The few studies that exist on the effects of CBD show that this cannabinoid can counteract some of the negative effects of THC, although their results have not always been consistent. The evidence favoring a beneficial effect of CBD therefore merits further investigation in studies in which the amounts and ratios of CBD and THC correspond to the daily practices of recreational cannabis use.
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. National Center for Biotechnology Information , U.
