When a person takes drugs or drinks some alcohol, it messes with his or her whole body. You may not notice it at first but it may show on your kids. You see when you consume drugs or alcohol it can screw up your reproductive system. As a result you could get a child with some kind of disability which would make you wonder why God wanted your kids to be like that, but in reality it could be your fault. That's why it is important to be really healthy before you get pregnant and after.
