Hi, Thanks for your query. I understand your concern. Yes, smoking marijunia pot in pregnancy has tremendous side effects in fetus & mother both. It may seize morning sickness vomiting, but the side effects it causes are hazardous.( name physical / mental/ intellectual / cognitive side effects in new born.. making it s life miserable. To control morning sickness you can- Chew dry snacks slowly before getting out of bed( water or liquids stimulate vomiting., be in bed for half hour & then get up to start your routine. Never starve. Take small/ multiple servings( 5-6 in a day ) of nutritious food you relish. Avoid spicy, oily or left over food.Avoid aerated drinks, _ get prescription from your doctor for preventing morning sickness.( like Doxinate pills 2 at bed time ) - Consult your doctor regularly for pregnancy check up. - Low blood pressure increases sickness.. Some times IV fluids can control such excessive vomiting. - Think that it s pregnancy hormones that cause the symptoms.. so your baby is getting good hormones & is growing well. This will stop when your body gets adjusted to the hormones.( usually by 3 months of pregnancy ) It s helpful to be positive. Thanks.
