Smoking & breastfeeding

No judgement please! This is not a usual thing for me! I had a cigarette like a moron (haven't smoked for a year!) And I pumped like maybe 30 minutes after smoking. I was thinking I won't get much and I'll just dump or use it for a milk bath. Of course I get more milk then usual so now I really feel like an idiot! What should I do??? Can I mix it with normal milk later to dilute it? I feel so guilty and irresponsible 😭🙈
