Possession of marijuana charge in Los Angeles but passed drug test

Question: Will passing a drug test by my employer help me get out of a possession of marijuana charge?
I was charged with possesion of marijuana a couple weeks ago and I told the cops that I do not smoke. I am unaware as to how the drugs got in my car but was given a drug test by my employer the following day and passed.
Answer: Technically you can be in possession of drugs even if you do not take them (ie. to sell them). It may help your attorney negotiate (and perhaps work out a deal for an informal diversion situation or dismissal), but it is not an automatic dismissal just because you tested negative on a drug test.
