Below, you’ll find some handy information, including facts, myths, and tips, that will help to make your THC detox a hassle-free and successful experience. What is a THC detox? In the most basic terms, detox refers to abstaining from consuming specific substances so that you can either avoid the build-up of trace amounts of those substances in your body, or so that you can remove the trace amounts that have already accumulated in your body from repetitive use. When it comes to cannabis, every time you smoke it or eat it, the THC builds up in your system. Over time, the buildup can become so much that your tolerance level can become extremely high, making it harder and harder to achieve a high. Additionally, if you need to take a drug test for any reason – to clear a background check for a new job, for example – when THC builds up in your system, it will most certainly show up in your urine or hair follicle test.
