An intervention letter is a prepared statement read during an intervention. It should be specific, loving, and end with clear consequences.

Structure

Open with your relationship and love. Share 2-3 specific instances where their addiction affected you (facts, not accusations). Express how it made you feel (using I statements). State what you are willing to do if they accept help. State what will change if they do not.

Tone

Loving but honest. Specific but not exhaustive. Concerned but not angry. Firm but not threatening. Read it aloud before the intervention to ensure the tone is right.

What to avoid

Generalizations (you always, you never). Shaming language. Bringing up old grievances unrelated to addiction. Threats you will not follow through on. Comparing them to others. Making it about you rather than concern for them.

Example opening

I am writing this because I love you and I am scared. On [date], I found you [specific observation]. I felt [emotion]. I cannot watch you destroy yourself anymore, and I am asking you to accept help today.
