These tinctures offers a great taste, and an effective dosing method. The most important difference between these two types of tincture is the presence of THC.
Broad-Spectrum CBD Tinctures are 0.00% THC. They will not cause you to fail a drug test.
Full Spectrum CBD Tinctures means that the entire array of cannabinoids present in the hemp is used to formulate it and they are present in the finished product. This means there will be trace but legal amounts of THC in the product (under 0.3% THC). This will not get you high, but it may cause you to fail a drug test.
