Weed breastfeeding question

My baby is 10 days old. I am a FTM and my breast milk is really taking it’s sweet time to produce anything substantial, my baby is taking formula and is now struggling to latch during the rare times I do want to breastfeed him. I’m also a single mom and it’s all been so tiring and disappointing and isolating for me. I want to relax and not beat myself up and I know hitting my old vape or having an edible would really help, but I don’t want to harm my baby. Can any mamas lmk if it’s okay to have a few puffs of my vape or an edible since I’m barely breastfeeding anyways? I do HOPE to breastfeed more exclusively but my milk isn’t there yet.
