Depends on the drug test. The "tip-cup" or "dipstrip" tests that most places use are not very accurate. Most drugs will not show up on those tests unless done very recently. However, lab tests are different. They are much more accurate. Even with the accuracy of a lab test it is unlikely that you will fail. Marijuana only lasts about four weeks even when it is used heavilly. Just a weekends worth of use is unlikely to show up that long after using.

A "bit" of marijuana will do no harm to the fetus, however habitual/daily smoking of marijuana (Or tobacco) will have adverse effects on the unborn baby.
