LL He's asking not about medication in general but illegal use of marijuana.

And since many work related drug testing is done with urine, and marijuana shows up in it, yes it is excreted in the urine.

The $64,000 question is whether or not that will be enough to make your urine also test positive. I have no clue and no idea where to look. Personally I wouldn't risk it. I'd find a partner who was d & d free, myself.

I know you like to believe that you are the most capable reader here, but no, he didn't specifically ask about marijuana, but merely mentioned an article about marijuana being passed through breast milk

I'm really surprised you didn't make an attempt to answer that "$64,000.00 question, since the answer is really not that difficult. It all depends on the frequency and amount of drugs that one takes and has in their system. If it is a drug that is excreted through the kidneys, and there is, for EXAMPLE, marijuana smoked a few times a day, every day, it is likely to transfer.

The real "$64,000.00" question is not finding a partner who is "D&D" free, but to know why they are using any particular type of drug to begin with. Like it or not, many states recognize medical marijuana, and if a person is using it as such (or any other prescribed drug), they have a prescription to cover them for their drug test. The "receiver" of the urine does not.

Drug tests detect not only drugs but metabolites as well. Metabolites are the byproducts of a substance after it has run through your system. To determine whether you will pass or not, it is important to know how much of the illicit metabolites are in your urine, as well as the test “cut off,” or Level of Detection (LOD). Usually marijuana tests will have a cutoff of 50ng/mL, but it can be as low as 25ng/mL. Home testing can tell you whether your level at the time of the test is above or below the 50ng/mL level, but it will not tell you the exact level of THC metabolites in your system.

Marijuana Detection Time and Half-Life of TetraHydraCannabinol

The half life of THC concentration is about 10 days. There is way too much variation to even approximate how long THC will be detected in the urine of an individual. Infrequent users with a fast metabolism will have the shortest detection time. Frequent or chronic users with a slow metabolism will have the longest detection times. The only way to estimate a detection time is to consider the lower and upper bounds (3-50 days), and estimate based on the factors outlined here.

To the best of My knowledge, any drug that can be detected from a urine sample will be passed on.

The point about metabolism is key.

Some drugs are extensively metabolized before being excreted, and some tests are specifically looking for the metabolic end-products.

If there is no renal excretion of the unchanged drug, then the end-product will generally be filtered out rapidly and effectively, if it is even absorbed in the first place. However, the person taking the drug will keep producing end-products for the duration of the drug in the system. And, as pointed out, if the drug is excreted in its original form, then these end-products will be produced in the recipient's body, which causes them to be detectable in the urine for far longer than if absorbed in their pre-metabolized state.

With all the usual disclaimers, I would point out that dronabinol is not excreted in the kidneys. Instead, its metabolites are excreted. Since it is highly lipid soluble and has a highly variable half-life with a long terminal half-life, a user of dronabinol will pass these metabolites in the urine at measurable levels for a long time. However, the receiver will be absorbing a limited fraction of the metabolites, and these will be rapidly excreted from the body. They do not persist for a significant time, and after the first visit to the bathroom, what little remains will be heavily diluted if adequate hydration is maintained (which is critical with urine consumption anyway).

So, long story short, it could be detected after a short time, but a bladderful on friday or saturday shouldn't turn up on monday. It is still better to have the paperwork on hand, though, and to use a home test kit (or, better yet, get a proper analysis of both your samples). This applies to dronabinol only, though. And, as noted, with all the caveats.

If anyone is curious about the right way to test, it's bringing an ordinary urine sample to a lab with an NMR and paying them to check for the drug one is concerned about. Universities are usually cheaper, if you can find someone with the time to spare for it, but the quality is going to depend significantly on the experience of the operator.
