A study from Indiana University suggests that mice injected with equal amounts of THC and CBD did not experience memory impairment or increased anxiety.
As medical and recreational legalization has taken root across the globe, THC levels in high-grade cannabis have increased almost 300 percent over the last few decades. On the other hand, CBD (cannabidiol) levels have actually decreased. While the combination of both THC and CBD may not be for everyone, it’s at least worth considering. A recent study has shown evidence that cannabis which contains higher levels of CBD may actually help counteract some of the possible harmful long-term effects that stem from smoking cannabis.
The Set up
A study conducted at Indiana University injected mice with both THC and CBD. In this study, researchers examined the effects of THC and CBD on both adolescent and adult mice. The mice were divided into five different test groups, one that received THC only; one that received CBD only; one that received equal amounts of both; as well as two other groups that received a placebo or no treatment at all. The cannabinoids were injected into the mice everyday for a period of three weeks. The whole study was then repeated again six weeks later.
The mice showed signs of both increased anxiety as well as memory impairment when injected with pure THC. However, when they received a dose of equal parts THC and CBD, the subjects did not experience any of the previously documented side effects. According to the lead study author Dr. Ken Mackie, the findings “suggest that strains of cannabis with similar levels of CBD and THC would pose significantly less long-term risk due to CBD’s protective effect against THC.”
The study also found that adolescent mice that were only given THC showed negative symptoms six weeks after treatment. Conversely, the adult mice did not. These observations do resonate with other studies that claim teenagers are at greater risk of long-term negative effects from cannabis use. However, both the adolescent and adult mice injected with equal parts THC and CBD showed no negative symptoms at all.
This study doesn’t necessarily give a conclusive answer about how CBD counteracts some of the potential negative effects of THC. However, it does help shed some light on cannabis research. Studies like this are opening up the doors for further experimentation and research moving forward.
Recreational cannabis users generally enjoy the high from THC. But it might be time to show some love and appreciation to the positive impact CBD plays. Especially in assisting and protecting its big brother THC.
