How long does weed stay in the blood?

Cannabis can typically be detected in the blood for up to 1 to 2 days after use for occasional users, while in regular users, it can be present for several days, sometimes up to a week or more. The duration depends on various factors, including the frequency of use, individual metabolism, and the potency of the cannabis consumed. However, THC, the active compound in cannabis, is rapidly metabolized and often clears from the bloodstream quicker than it does from other bodily fluids, like urine.
