A high dose of CBD could increase the intoxicating effect of THC, according to a new study

A recent study published in Clinical Pharmacology and Therapeutics reinforces the widely held belief regarding the effects of the CBD about THC.

For years, it has been said that CBD counteracts or reduced the euphoric effect caused by THC. However, this research suggests that CBD, at high doses, may actually intensify the effects of THC rather than dampen them.

Results of the Study on the Interaction Between THC and CBD

The study, conducted by a team of seven scientists from the Netherlands and the United States, was a randomized, double-blind, placebo-controlled trial involving 37 healthy volunteers. The study aimed to test the hypothesis that CBD could reduce the adverse psychoactive effects of THC, thereby making therapeutic THC more tolerable for people suffering from chronic pain. Surprisingly, the study’s results suggest the opposite.

Participants who consumed a high amount of dose of CBD (450 mg) along with a relatively low dose of THC (9 mg) reported a level increased psychoactive effects. In contrast, lower doses of CBD (10 mg and 30 mg) did not significantly alter the THC experience.

This finding is remarkable because it contradicts the popular belief that any dose of CBD relieves anxiety or mitigates the overly intense effects of THC. On the contrary, the results suggest that at higher doses, the Cannabidiol enhances the subjective, psychomotor, and cognitive effects of THC, which is ultimately consistent with the biphasic effect of CBD.

The Science Behind CBD's Effect on THC

The lead author of the study, Geert van Groeneveld, a professor at Leiden University Medical Center and director general of the Center for Human Drug Research, emphasized that the study’s findings contradict the notion that CBD helps reduce the negative effects THC.

According to van Groeneveld, «CBD does not in any way mitigate the psychoactive effects of THC or reduce anxiety. On the contrary, at higher doses, it enhances the effects of THC because CBD inhibits the breakdown of THC in the liver.».

This interaction between CBD and THC occurs because CBD inhibits the enzyme responsible for breaking down THC in the liver. As a result, a greater amount of THC remains active in the blood for a longer period of time, leading to a more intense psychoactive experience. This could explain why study participants reported stronger effects when using higher doses of CBD in addition to THC.

Implications for cannabis-based therapies

These findings may have far-reaching implications for cannabis-based therapies.

One of the main objectives of combining the CBD and THC in medical treatments has been to reduce psychoactive side effects, making the treatment more tolerable for patients. However, this study suggests that, at least at high doses, the CBD does not reduce the psychoactive effects of THC and could even intensify them.

Nor did the research reveal any profits additional in in terms of pain relief by adding CBD to THC. This raises questions about the effectiveness of the CBD-THC combinations in pain management, because the hoped-for synergy No difference between the two cannabinoids was observed in this study.

A broader understanding of the interactions between cannabinoids

This study is part of a growing body of research aimed at understanding the complex interactions between the various cannabinoids. While the THC and the CBD Although they have often been studied in isolation, it is becoming increasingly clear that the whole cannabis plant – which includes a variety of cannabinoids, of terpenes and other compounds—may offer greater therapeutic benefits.

For example, a separate scientific journal published in the’International Journal of Molecular Sciences Earlier this year, a study highlighted the potential of these interactions. The magazine noted that «the complex interaction between the phytocannabinoids »and biological systems offers hope for new therapeutic approaches," suggesting that the medicine made from whole cannabis plants could pave the way for new innovations in cannabis-based treatments.

Other studies have also shown that combinations of THC when combined with other cannabinoids or compounds, can lead to more intense psychoactive experiences than THC alone. This could be due to the’entourage effect, where the various compounds in cannabis work together to produce effects that are more potent than any single compound acting alone.

Terpenes and Their Role in Modulating the Effects of THC

It is interesting to note that if CBD does not reduce the side effects of the THC, another compound found in cannabis, the D-limonene, appears to have an impact on anxiety and paranoia associated with THC use. A study published earlier this year revealed that the D-limonene, a terpene present in both the Cannabis and citrus fruits, could reduce anxiety among participants who had consumed THC. However, the study found that D-limonene had little effect on other aspects of the’THC experience.

The researchers noted that inhaling the vaporized terpene did not produce any notable acute effects different from those of a placebo, suggesting that its impact may be more subtle than previously thought. Nevertheless, the fact that it can reduce anxiety without significantly altering other subjective or physiological effects is an intriguing finding, particularly for those who wish to mitigate some of the less desirable effects of THC.

Moving Forward with Cannabis Research

The results of these studies highlight the complexity of the Cannabis as a medicinal plant. Whereas the THC and the CBD While these have been the focus of most research conducted to date, it is becoming increasingly clear that the full therapeutic potential of cannabis may lie in the complex interaction between the many cannabinoids, terpenes, and other compounds of the plant.
