Popularity of cannabis is on the rise. Naturally, problems related to it are also increasing. Now scientists from UCL used functional magnetic resonance imaging to see how different strains of cannabis impact brain function. They found that the more cannabidiol (CBD) there is in a strain of cannabis, the lower the impairment to brain function is.
Cannabis has two main compounds that everyone’s been talking about – psychoactive tetrahydrocannabinol (THC) and CBD, which is not psychoactive, but has a lot of health benefits. People are looking for THC, because it is what provides that high, which is encouraging people to smoke cannabis. However, although these cases are still rare, THC can cause addiction and even psychosis. Meanwhile CBD has a lot of health benefits that are worth exploring. However, because cannabis is mostly popular as a recreational drug, in the last couple of decades new strains have been made to contain more THC and less CBD. Now scientists say that it’s not good.
Scientists monitored brain activity at rest in 17 people after taking different strains of cannabis. They found that low-CBD strains impaired functional connectivity in the brain’s default mode, while high-CBD strain caused only a minimal disruption. Scientists say that this could mean that CBD counteracts some of
