A person who smokes marijuana often feels the impact of its effects immediately. But some people take cannabis via other consumption methods where some time is required before anything is felt. However, regardless of the method of consumption used or the reason for consumption a certain fact is that once consumed, the marijuana metabolites will remain active in the body for a definite amount of time. What this means is that there will be chemical traces of cannabis present in the body. These chemicals are referred to as cannabinoids, and they can be detected through an individual’s urine, blood, saliva, hair, and even fingernails.Â
