Some say these tinctures will give you the best results as all the components of the plant can work synergisticly with one another, giving the "entourage effect". Though the THC content on these tinctures is not enough to give you any psychoactive effects, it is enough to potentially fail a drug test. The Remedy does not recommend using full spectrum tinctures if you are subject to any drug testing and would suggest a THC Free option, made with CBD Isolate.
