I also thought that CBD oil doesn’t really work, and it is a placebo effect, and it will work only if you really believe in that. But a couple of years ago, I have a horrible headache almost every evening. I barely survived, and medications didn’t help me. I was skeptical about CBD oil but decided to give it a try. Surprisingly, it worked for me, and I started to believe all those people who say that it works. I even ordered a few compatible pods to vape on knockoutcbd.com. I use it in the evening when I feel tired from work and want to relax.
