First of all, all of the research I've read indicates that THC can be stored in the cells for up to THREE months. For example:

But the fact that there's THC in the cells doesn't mean that the associated SERUM levels of THC cause intoxication. In fact, almost all studies indicate that serum THC levels are very, very low within a few hours of taking the last puff, and become undetectable even in very heavy smokers within a day or two.
Sigh. Just because a doc has a .edu address doesn't mean it's accurate. THC rapidly degrades in the body to THC-COOH, which is not psychoactive. It accumulates in fat tissue & is only slowly released in urine. It's the basis of urine testing for cannabis. In no way does its presence indicate that the subject was intoxicated at the time of the test, despite widespread belief to the contrary.
Google THC-COOH for more than you wanted to know.
