Can I get an annulment because my husband has a drug problem I didn't know about?

In Illinois there is no such thing as an annulment, It is called a declaration of invalidity. Just like there is no such thing as divorce , it is a dissolution of marriage. Disregarding that, the ground for a declaration of invalidity are extremely limited. They are: (1) a party lacked capacity to consent to the marriage at the time the marriage was solemnized, either because of mental incapacity or infirmity or because of the influence of alcohol, drugs or other incapacitating substances, or a party was induced to enter into a marriage by force or duress or by fraud involving the essentials of marriage; (2) a party lacks the physical capacity to consummate the marriage by sexual intercourse and at the time the marriage was solemnized the other party did not know of the incapacity; (3) a party was aged 16 or 17 years and did not have the consent of his parents or guardian or judicial approval; or (4) the marriage is prohibited. It does not appear that you fall within any of those grounds.

Unfortunately, you do not meet the requirements for annulment in IL. Illinois statute states that in order to have a marriage annulled, you must meet one of the following. (1) a party lacked capacity to consent to the marriage at the time the marriage was solemnized, either because of mental incapacity or infirmity or because of the influence of alcohol, drugs or other incapacitating substances, or a party was induced to enter into a marriage by force or duress or by fraud involving the essentials of marriage; (2) a party lacks the physical capacity to consummate the marriage by sexual intercourse and at the time the marriage was solemnized the other party did not know of the incapacity; (3) a party was aged 16 or 17 years and did not have the consent of his parents or guardian or judicial approval; or (4) the marriage is prohibited.
