When it comes to testing for marijuana use, blood tests are not often used. This is because blood tests have a narrow window of time to detect marijuana use. These tests typically only work within three to four hours when a person uses marijuana, which is when THC is still in the bloodstream.

Although some former users report having these types of dreams years after they stop smoking pot. After smoking pot heavily for a few months or longer—whether as a regular pattern, in binges, or due to addiction—you may experience withdrawal symptoms when abruptly stopping its use.

Testing urine for marijuana (THC-COOH metabolite to be exact) is the standard procedure that employers use in order to determine if you’ve been using cannabis.
