Talk to his attorney now. He wasn't "pro per," own his own, with two felony drug charges. That attoney need to get into court and have the court order him released. Writing a question on this forum is not the correct thing to do. If he had the PD, call their office. If he had a private attorney call them, now.
You absolutely need to call his attorney. The State could've also dismissed without prejudice to add charges or reinidict. If so, it will show as dismissed on the court website. But, knew charges could already be in place. Your husband's attorney is in the best position to look into this for.
