Yes. A biological parent's substance abuse is a factor that courts consider in Missouri, and it often supports the case for stepparent adoption.
How substance abuse factors into adoption:
Path 1: Abandonment (most common)
Drug-addicted parents frequently have no meaningful contact with their children for extended periods. If the parent has had no contact for 6+ months (RSMo § 453.040), abandonment can be established — and substance abuse is often the underlying reason.
Path 2: Consent
Some substance-addicted parents recognize they cannot parent effectively and voluntarily consent to the adoption. This happens more often than people expect.
Path 3: Court-ordered termination
In some cases, substance abuse combined with neglect, failure to complete treatment programs, or endangering the child can be grounds for involuntary termination of parental rights.
What you need to document:
- The parent's absence and lack of contact (dates, duration)
- Any history of failed attempts to maintain the relationship
- The stability you and your spouse provide
Important: You do NOT need to prove the parent is an addict. You need to prove they have abandoned the child. The substance abuse may explain the abandonment, but the court focuses on the child's experience — no contact, no relationship.
