You’re probably aware that there are different types of cannabis strains. Some of them will get you high (they’re rich in THC and they have low CBD levels), some just help you relax (High-CBD, low-THC). Most studies have examined high-THC strains so far, as CBD strains are more difficult to find in some areas of Canada.
So how do those high-CBD strains affect our sleep? According to a 2006 study conducted in both lights-on and lights-off environments, cannabidiol increases alertness with the lights on and has no distinguishable effects on lights-off sleep. In conclusion, the study have found that CBD holds therapeutic promise for people suffering from somnolence, or for those who struggle with excessive daytime drowsiness due to a poor night’s rest.
