Funny as this sounds, some people have mistakenly gotten high in their search for a reliable and good CBD brand. Speaking from experience, I also have—at least on six different occasions. I found that not all broad or full-spectrum CBD brands abide by the federally allowed 0.3 percent limit for THC in a CBD-based product. Not to mention that I used more than the recommended dose.
