Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Consuming alcohol and recreational drugs are known to be particularly dangerous for a developing baby. Any amount of these substances is considered unsafe during pregnancy. In general, using such drugs during pregnancy can result in the following: miscarriage, stillbirth, small for gestational age, low birth weight, premature birth, birth defects, sudden infant death syndrome and drug dependency in the baby. Drugs may not have much effects on abortion process, but can result in increased amount and number of days of bleeding. Abstain from consumption of such drugs in future pregnancies. Hope I have answered your query. Let me know if I can assist you further.
