Yes you should call a locally experienced criminal defense attorney for the both of you....HS11550 alleges you were under the influence of a controlled substance and carries mandatory minimum custody in San Diego if convicted of that offense.
Your first court date is your arraignment where you will likely enter a not guilty plea and fight the charges, assuming the prosecutor's office files charges. HS11550 is a misdemeanor and your presence would not be required in court if you hire a private attorney.

"11550 HS" refers to Health and Safety Code section 11550, otherwise known as "Being Under the Influence of a Controlled Substance." You should consult with a local defense attorney right away to ensure the best possible outcome. Having practiced law in San Diego for a number of years I assure you that time is of the essence since the earlier an attorney gets involved the greater the attorney's opportunity to resolve the case on favorable terms. It's important that you provide your attorney whatever documentation you have regarding your medical treatments and prescriptions. Also, because of your employment you'll also want an attorney knowledgeable with the UCMJ to ensure the arrest itself does not have adverse professional repercussions. Good luck.
