There are several factors that contribute to how long CBD might stay in one’s system. The factors that might contribute are as follows: your history with CBD and cannabis products (tolerance to cannabinoids), your body & metabolism speed, how much CBD you use, if you have a full stomach or not, and how you use the CBD product. Based on these factors, limited research shows that CBD will stay in your bloodstream for 2-5 days before being processed. That doesn’t mean that it is how long you’ll feel the impact of CBD; rather, how long (based on what we know) CBD actually stays in your body.
