If the drug test is not for a couple months then quit smoking, you will easily pass. If you are only 16 years old and have already fun afoul with the law - I think that should be a wake call for you and it would be wise to stay CLEAN until you straighten up your life.

You are still young and will have plenty of time to enjoy smoking marijuana; sacrifice your toking and clean up your system and your troubles.

Good luck and quit stealing.
