I think it would be better if you didn't smoke in some ones house without them knowing. if you're in a period of life where you have to hide the fact that you smoke from the person(s) you are living with then it's best that you learn how to roll, and ditch the devices. It's a lot easier to keep some papers handy with your sack anyway, that way you can remove yourself from their living space before you toke up, its a lot more pleasant to smoke outdoors if you ask me.:thumbsup:
