Will I pass a drug test if I take CBD? A more common question than you would expect. CBD and THC are two completely different elements. CBD is used purely for medicinal benefits, whereas THC is the psychoactive element in the marijuana plant that causes you to get high. Because CBD has no psychoactive side affects, CBD is completely legal to use, and therefore it is not tested for in a drug test. When a person takes a drug test, the test is looking for the element THC. CBD is a legal substance that can be used in all 50 states, and it is a truly effective way to handle a lot of a persons mental and physical stresses. CBD is a natural supplement that should be apart of anyone daily supplement regimen. You should feel no legal pressure when you purchase and use CBD products. And since drug tests are not searching for CBD users, you should be confident in knowing that you will only see positive outcomes after using CBD products.
