Smoking is relaxing

Is it okay to smoke here and there while breast feeding? It helps me calm down and helps me relax and take stress away. Not everyday it’s been about a week sink I last took 2 hits from a bowl.. and if I would smoke again it would be a few hits not a whole bowl.. anyone ever done that and If so how did your baby act? And can you drug test your baby to see if it’s in their System?
