It is not a simple question that can be answered on this type of forum. There are many factors that would need to be considered and evaluated. Your husband may have some major problems including illegal re-entry and a drug charge that may make him inadmissible from returning to the U.S. I strongly suggest that you contact an experienced immigration attorney for a face-to-face consultation and give him/her all of the facts surrounding your husband's situation. He/she would then be in a better position to analyze his case and advise you of his options.
