CBD products are widely available and are often used for their therapeutic effects. However, it is important to note that CBD products may contain trace amounts of THC, the compound in cannabis that causes you to get high. While the amount of THC in CBD products is usually too small to cause a positive drug test result, there is no guarantee that it won't. To ensure that you pass a drug test, it is best to avoid using any type of CBD product. Hemp shampoo is unlikely to cause a false positive in a hair test for two reasons.
Firstly, research has shown that applying hemp oil to hair as a cosmetic treatment may result in the incorporation of THC, CBN, CBD and, in one case, the metabolite THC-OH. However, drug tests usually only detect THC or one of its metabolites. Secondly, light cannabis users have tested positive for THC (39%), CBN (29%) and CBD (11%), but only 3% and 11% tested positive for the metabolites THC-OH and THC-COOH respectively. When purchasing a CBD oil product, it is important to do your research and ensure its purity. This is especially true if you need to undergo a drug test.
Similarly, it is important to be aware that CBD shampoo contains trace amounts of THC and should be avoided if you need to take a drug test. In conclusion, while the information suggests that CBD won't cause anyone to fail a drug test, there is no way to guarantee this. The only way to ensure that you pass a drug test is to refrain from using any type of CBD product.
