Cannabis

So I have birth 3 months ago & I was also breast feeding but then when the baby turn 3 months I stop breast to smoke, I think that was a phase.. idk but I was really depressed and going through mixed emotions. Anyways I’ve been smoke a lot like every day 3 times throughout the day. I don’t want to smoke anymore I wanna go back to breast feeding. How long afterwards smoking can I go start breast feeding ? ( please no rude comments)
