Dipping while pregnant?

So I'm 9 weeks pregnant and me and my hubby used to chew every now and then. Now that I'm pregnant, I haven't dipped once. My hubby does it still, but not in front of me because he knows I will crave it. But I wanna know if it is safer than smoking? If I dip just once, will it effect my baby? And how would it get into my blood if it's just in my mouth? Help please!!
