Smoking and pregnancy

I'm 28 weeks along and since my first trimester Ive been smoking to get over my nausea and allow me to actually getup take care of my home and eat. I still don't feel great and usually smoke at night with my SO. So a joint split between us. Some days if I'm feeling really bad I will take 3-4 hits from a roach in the late morning. Reading the studies and other moms experiences I'm not worried about the baby really. Baby moves a shit ton and is growing great. His heartbeat is always strong 140-150. I'm concerned more about whether I'm number one being tested at every midwife visit ? And two will I or baby be tested atmy hospital (women and infants in RI if anyone has experience). I honestly don't know if I'll be able to stop completely, would I have to at 35 weeks or so ?

Edit to add living in RI it is decriminalized and medical cards are given out like candy. I guess baby could come early but my others were 11&7 days late . I can't find straight info on if tests are done at the hospital and if it's always done or only when they feel it's needed. My hospital has never taken my baby's diapers before and there's just the one foot prick blood test. Nor do they take babies to a nursery they are with moms at all times
