Never take any drugs while pregnant. Best to be prudent. also avoid, raw meat/eggs, mayonnaise, Cesar dressing, soft cheeses(feta, Brie, blue), shark, swordfish, mackerel, most all fresh watter fish(salmon, trout). also make sure to reheat all deli meat, and cook all veggies. you first priority during pregnancy should be your babies health, as I'm sure you already know.
I was advised by my doctor to keep toking during my pregnancy to help with my insomnia, migraines, asthma, back pain and morning sickness. A friend of mine was so sick during her entire pregnancy that she had to be fed intraveniously(sp?) Her doctor prescribed some THC capsules to help her nausea. The pills didn't work as well as smoking cannabis, so her doctor prescribed her medicinal marajuana. It is a healing herb; used in moderation it can help you stay healthy during your pregnancy. Congrats! I wish you and your baby all the best.
