I doubt some to take away the sickness and pain is going to hurt, maybe you should start cooking it or vaporizing to be healthier If you smoke a lot now you may want to try and cut back so you dont start smoking a lot more in your pregnancy. And I doubt you'll be able to smoke nearly as much as you do know for the first few months at least when the babies born so if you would find it hard to quite altogether then cutting back now would be a good idea.
