No, absolutely not. Snuff is smokeless tobacco and nicotine goes directly into your bloodstream to the baby, which is very dangerous. Throw it away right now and speak to your doctor if you need help quitting.
Hey, honestly, please avoid snuff completely because it has nicotine which is not safe for the baby at all. If you are having cravings, try chewing some fennel seeds (saunf) instead and don't stress too much, you can easily quit this phase!
Please, please do not use snuff! I used to worry about even smelling paint fumes, and tobacco is so much worse for the baby's development. If you've already had some, don't panic, just stop using it immediately and let your gynac know.
I lost a baby before, so I always tell moms to be extra careful. Tobacco in any form, including snuff, increases the risk of complications significantly. Please protect your little one and stay completely away from it, it's just not worth the risk.
