7. Future Directions
The current investigation sets the stage for additional future investigations regarding CBD effects on sleep and immunological function. The improvements seen in perceived sleep quality following CBD administration are promising, and future work using PSG following CBD administration would be innovative in uncovering the effects of CBD on sleep architecture. Furthermore, increased CBD dosing, chronic CBD use, and additional CBD administration modes such as oral mucosal spray and topical gels in varying healthy and diseased populations will help strengthen the current body of clinical literature on CBD, and further explain its potential effects in the human population. Finally, with the differences in bioavailability between biological sexes, investigating the effects of CBD on males and females will help bolster the current body of literature and improve the accuracy of CBD dosing between sexes.
