The results of the evaluation of pharmacokinetics, to see if interaction between the drugs occurred, were as follows. Peak CBD plasma concentrations of the 400 and 800 mg group were measured after 4 h in the first session (CBD administration 2 h after light breakfast). Peak urinary CBD and its metabolite concentrations occurred after 6 h in the low CBD group and after 4 h in the high CBD group. No effect was evident for urinary CBD and metabolite excretion except at the higher fentanyl dose, in which CBD clearance was reduced. Importantly, fentanyl coadministration did not produce respiratory depression or cardiovascular complications during the test sessions and CBD did not potentiate fentanyl’s effects. No correlation was found between CBD dose and plasma cortisol levels.

Conclusion: This review also illustrates that some important toxicological parameters are yet to be studied, for example, if CBD has an effect on hormones. Additionally, more clinical trials with a greater number of participants and longer chronic CBD administration are still lacking.

To the best of our knowledge, no acute studies were performed that solely concentrated on CBD glycemic effects. Moreover, the only acute study that also measured CBD effect on appetite was the study we described above, comparing different cannabis strains. In this study, the strain high in CBD elicited less appetite increase compared to the THC-only strain. 52.

A randomized, double-blind, crossover, placebo-controlled trial was conducted in 16 healthy nonanxious subjects using a within-subject design. Oral Δ9-THC=10 mg, CBD=600 mg, or placebo was administered in three consecutive sessions at 1-month intervals. The doses were selected to only evoke neurocognitive effects without causing severe toxic, physical, or psychiatric reactions. The 600 mg CBD corresponded to mean (standard deviation) whole blood levels of 0.36 (0.64), 1.62 (2.98), and 3.4 (6.42) ng/mL, 1, 2, and 3 h after administration, respectively.

The following study, which showed a positive effect of CBD on obsessive compulsive behavior in mice and reported no side effects, exemplifies the existing pharmacokinetic differences. 5 When mice and humans are given the same CBD dose, more of the compound becomes available in the mouse organism. This higher bioavailability, in turn, can cause larger CBD effects.

Psychosis.

In a study with a total of 21 Parkinson’s patients (without comorbid psychiatric conditions or dementia) who were treated with either placebo, 75 mg/day CBD or 300 mg/day CBD in an exploratory double-blind trial for 6 weeks, the higher CBD dose showed significant improvement of quality of life, as measured with PDQ-39. This rating instrument comprised the following factors: mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort. For the factor, “activities of daily living,” a possible dose-dependent relationship could exist between the low and high CBD group—the two CBD groups scored significantly different here. Side effects were evaluated with the UKU (Udvalg for Kliniske Undersøgelser). This assessment instrument analyzes adverse medication effects, including psychic, neurologic, autonomic, and other manifestations. Using the UKU and verbal reports, no significant side effects were recognized in any of the CBD groups. 73.

Clinical chronic (lasting longer than a couple of weeks) studies in humans are crucial here but were mostly still lacking at the time of writing this review. They hopefully will shed light on the inconsistencies observerd in animal studies. Chronic studies in humans may, for instance, help to test whether, for example, an anxiolytic effect always prevails after chronic CBD treatment or whether this was an artifact of using different animal models of anxiety or depression. 2,18.

Bergamaschi et al. describe a chronic study, where a teenager with severe side effects of traditional antipsychotics was treated with up to 1500 mg/day of CBD for 4 weeks. No adverse effects were observed and her symptoms improved. The same positive outcome was registered in another study described by Bergamaschi et al., where three patients were treated with a starting dose of CBD of 40 mg, which was ramped up to 1280 mg/day for 4 weeks. 1 A double-blind, randomized clinical trial of CBD versus amisulpride, a potent antipsychotic in acute schizophrenia, was performed on a total of 42 subjects, who were treated for 28 days starting with 200 mg CBD per day each. 67 The dose was increased stepwise by 200 mg per day to 4×200 mg CBD daily (total 800 mg per day) within the first week. The respective treatment was maintained for three additional weeks. A reduction of each treatment to 600 mg per day was allowed for clinical reasons, such as unwanted side effects after week 2. This was the case for three patients in the CBD group and five patients in the amisulpride group. While both treatments were effective (no significant difference in PANSS total score), CBD showed the better side effect profile. Amisulpride, working as a dopamine D2/D3-receptor antagonist, is one of the most effective treatment options for schizophrenia. CBD treatment was accompanied by a substantial increase in serum anandamide levels, which was significantly associated with clinical improvement, suggesting inhibition of anandamide deactivation via reduced FAAH activity.

Truly chronic studies with CBD are still scarce. One can often argue that what the studies call “chronic” CBD administration only differs to acute treatment, because of repeated administration of CBD. Nonetheless, we also included these studies with repeated CBD treatment, because we think that compared to a one-time dose of CBD, repeated CBD regimens add value and knowledge to the field and therefore should be mentioned here.

In nonobese diabetes-prone female mice (NOD), CBD was administered i.p. for 4 weeks (5 days a week) at a dose of 5 mg/kg per day. After CBD treatment was stopped, observation continued until the mice were 24 weeks old. CBD treatment lead to considerable reduction of diabetes development (32% developed glucosuria in the CBD group compared to 100% in untreated controls) and to more intact islet of Langerhans cells. CBD increased IL-10 levels, which is thought to act as an anti-inflammatory cytokine in this context. The IL-12 production of splenocytes was reduced in the CBD group and no side effects were recorded. 32.

A press release by GW Pharmaceuticals of September 15th, 2015, described 88 patients with treatment-resistant schizophrenic psychosis, treated either with CBD (in addition to their regular medication) or placebo. Important clinical parameters improved in the CBD group and the number of mild side effects was comparable to the placebo group. 2 Table 2 shows an overview of studies with CBD for the treatment of psychotic symptoms and its positive effect on symptomatology and the absence of side effects. 69.

A study, where a regimen of 6×100 mg CBD daily was coadministered with hexobarbital in 10 subjects, found that CBD increased the bioavailability and elimination half-time of the latter. Unfortunately, it was not mentioned whether this effect was mediated via the cytochrome P450 complex. 16.

The largest CBD study conducted thus far was an open-label study with Epidiolex in 261 patients (mainly children, the average age of the participants was 11) suffering from severe epilepsy, who could not be treated sufficiently with standard medication. After 3 months of treatment, where patients received CBD together with their regular medication, a median reduction of seizure frequency of 45% was observed. Ten percent of the patients reported side effects (tiredness, diarrhea, and exhaustion). 2.

In a 4-week open trial, CBD was tested on Parkinson’s patients with psychotic symptoms. Oral doses of 150–400 mg/day CBD (in the last week) were administered. This led to a reduction of their psychotic symptoms. Moreover, no serious side effects or cognitive and motor symptoms were reported. 66.

Relevant Preclinical Studies.

These proteins are also expressed at the blood–brain barrier, where they can pump out drugs such as risperidone. This is hypothesized to be a cause of treatment resistance. 16 In addition, polymorphisms in these genes, making transport more efficient, have been implied in interindividual differences in pharmacoresistance. 10 Moreover, the CBD metabolite 7-COOH CBD might be a potent anticonvulsant itself. 14 It will be interesting to see whether it is a P-gp substrate and alters pharmacokinetics of coadministered P-gp-substrate drugs.

Various studies have been performed to study CBD anticancer effects. CBD anti-invasive actions seem to be mediated by its TRPV1 stimulation and its action on the CB receptors. Intraperitoneal application of 5 mg/kg b.w. CBD every 3 days for a total of 28 weeks, almost completely reduced the development of metastatic nodules caused by injection of human lung carcinoma cells (A549) in nude mice. 36 This effect was mediated by upregulation of ICAM1 and TIMP1. This, in turn, was caused by upstream regulation of p38 and p42/44 MAPK pathways. The typical side effects of traditional anticancer medication, emesis, and collateral toxicity were not described in these studies. Consequently, CBD could be an alternative to other MMP1 inhibitors such as marimastat and prinomastat, which have shown disappointing clinical results due to these drugs’ adverse muscoskeletal effects. 37,38.

CBD was shown to be able to influence migratory behavior in cancer, which is also an important aspect of embryogenesis. 1 For instance, it was recently shown that CBD inhibits Id-1. Helix-loop-helix Id proteins play a role in embryogenesis and normal development via regulation of cell differentiation. High Id1-levels were also found in breast, prostate, brain, and head and neck tumor cells, which were highly aggressive. In contrast, Id1 expression was low in noninvasive tumor cells. Id1 seems to influence the tumor cell phenotype by regulation of invasion, epithelial to mesenchymal transition, angiogenesis, and cell proliferation. 34.

High CBD concentrations (1 mM) inhibited progesterone 17-hydroxylase, which creates precursors for sex steroid and glucocorticoid synthesis, whereas 100 μM CBD did not in an in vitro experiment with primary testis microsomes. 45 Rats treated with 10 mg/kg i.p. b.w. CBD showed inhibition of testosterone oxidation in the liver. 46.

Forty-eight participants received subanxiolytic levels (32 mg) of CBD, either before or after the extinction phase in a double-blind, placebo-controlled design of a Pavlovian fear-conditioning experiment (recall with conditioned stimulus and context after 48 h and exposure to unconditioned stimulus after reinstatement). Skin conductance (=autonomic response to conditioning) and shock expectancy measures (=explicit aspects) of conditioned responding were recorded throughout. Among other scales, the Mood Rating Scale (MRS) and the Bond and Bodily Symptoms Scale were used to assess anxiety, current mood, and physical symptoms. “CBD given postextinction (active after consolidation phase) enhanced consolidation of extinction learning as assessed by shock expectancy.” Apart from the extinction-enhancing effects of CBD in human aversive conditioned memory, CBD showed a trend toward some protection against reinstatement of contextual memory. No side/adverse effects were reported. 53.

A similar effect was previously described in anxiety experiments, where CBD proved to be only anxiolytic in subjects where stress had been induced before CBD administration. Elevated glutamate levels have been proposed to be responsible for ketamine’s fast antidepressant function and its dysregulation has been described in OBX mice and depressed patients. Chronic CBD treatment did not elicit behavioral changes in the nonoperated mice. In contrast, CBD was able to alleviate the affected functionality of 5HT1A receptors in limbic brain areas of OBX mice. 18 and references therein.

Neurological and neuropsychiatric effects.

Fifteen neuroleptic-free patients with Huntington’s disease were treated with either placebo or oral CBD (10 mg/kg b.w. per day) for 6 weeks in a double-blind, randomized, crossover study design. Using various safety outcome variables, clinical tests, and the cannabis side effect inventory, it was shown that there were no differences between the placebo group and the CBD group in the observed side effects. 6.

An in vitro study using three types of trophoblast cell lines and ex vivo placenta, perfused with 15 μM CBD, found BCRP inhibition leading to accumulation of xenobiotics in the fetal compartment. 17 BCRP is expressed at the apical side of the syncytiotrophoblast and removes a wide variety of compounds forming a part of the placental barrier. Seventy-two hours of chronic incubation with 25 μM CBD also led to morphological changes in the cell lines, but not to a direct cytotoxic effect. In contrast, 1 μM CBD did not affect cell and placenta viability. 17 The authors consider this effect cytostatic. Nicardipine was used as the BCRP substrate in the in vitro studies, where the Jar cell line showed the largest increase in BCRP expression correlating with the highest level of transport. 17,and references therein.

Various vital signs were also measured (blood pressure, respiratory/heart rate, oxygen saturation, EKG, respiratory function): CBD did not worsen the adverse effects (e.g., cardiovascular compromise, respiratory depression) of iv fentanyl. Coadministration was safe and well tolerated, paving the way to use CBD as a potential treatment for opioid addiction. The validated subjective measures scales Anxiety (visual analog scale [VAS]), PANAS (positive and negative subscores), and OVAS (specific opiate VAS) were administered across eight time points for each session without any significant main effects for CBD for any of the subjective effects on mood. 10.

Another model for BD and schizophrenia is PPI of the startle reflex both in humans and animals, which is disrupted in these diseases. Peres et al., list five animal studies, where mostly 30 mg/kg CBD was administered and had a positive effect on PPI. 20 Nonetheless, some inconsistencies in explaining CBD effects on PPI as model for BD exist. For example, CBD sometimes did not alter MK-801-induced PPI disruption, but disrupted PPI on its own. 20 If this effect can be observed in future experiments, it could be considered to be a possible side effect.

A second caveat of preclinical studies is that supraphysiological concentrations of compounds are often used. This means that the observed effects, for instance, are not caused by a specific binding of CBD to one of its receptors but are due to unspecific binding following the high compound concentration, which can inactivate the receptor or transporter.

Epileptic patients were treated for 135 days with 200–300 mg oral CBD daily and evaluated every week for changes in urine and blood. Moreover, neurological and physiological examinations were performed, which neither showed signs of CBD toxicity nor severe side effects. The study also illustrated that CBD was well tolerated. 65.

Some studies indicate that under certain circumstances, CBD acute anxiolytic effects in rats were reversed after repeated 14-day administration of CBD. 2 However, this finding might depend on the used animal model of anxiety or depression. This is supported by a study, where CBD was administered in an acute and “chronic” (2 weeks) regimen, which measured anxiolytic/antidepressant effects, using behavioral and operative models (OBX=olfactory bulbectomy as model for depression). 18 The only observed side effects were reduced sucrose preference, reduced food consumption and body weight in the nonoperated animals treated with CBD (50 mg/kg). Nonetheless, the behavioral tests (for OBX-induced hyperactivity and anhedonia related to depression and open field test for anxiety) in the CBD-treated OBX animals showed an improved emotional response. Using microdialysis, the researchers could also show elevated 5-HT and glutamate levels in the prefrontal cortex of OBX animals only. This area was previously described to be involved in maladaptive behavioral regulation in depressed patients and is a feature of the OBX animal model of depression. The fact that serotonin levels were only elevated in the OBX mice is similar to CBD differential action under physiological and pathological conditions.
