In general, the effects of CBD can last in the body for a period of two to eight hours. However, there are many different factors that can influence how quickly cannabidiol is absorbed by the body and how long it lasts. Generally speaking, the effects of CBD can last for two to six hours. A randomized clinical trial with placebo found that, out of 24 volunteers, the median time it took for subjects to reach maximum plasma concentration was four hours.
This means that the effects of CBD can last up to eight hours. The time it takes for CBD to take effect and the duration of its effects will vary from person to person. It is important to note that all hemp-derived CBD products will contain less than 0.3% THC, meaning they cannot get you high. The CBD oil used in these products is derived from organically grown hemp plants that have been certified by Good Manufacturing Practices (GMP) for quality and consistency and are free of THC.
