As the original OLD FRACK, let me add a totally hippie perspective to this. If your MOM is totally ADDICTED to NICOTINE and is not willing to shake it, please consider trying to MTIGATE the damage by getting her to buy a VOLCANO VAPORIZER.
If you have been following some of the posts by EricS & myself, you will know that the Volcano Vaporizer which was originally intended for Medical Marijuana users, also works quite efficiently on Tobacco. It's hard core German Engineering that vaporizes the active ingredients in either Tobacco or Marijuana into a non combusted vapor. The University of San Francisco and others have documented that this vapor (not smoke) system avoids the Cancer causing carcinogens of smoking. NO DOUBT THAT QUITTING SMOKING is the very best and optimal solution here. Still, as human beings, we are often weak in the face of addictions. If your Mom is hell bent on getting that Nicotine HIGH, buy her a Vaporizer. I fervently hope she will listen to reason and just quit, but it is a wicked world we live in. Realize this is an AWFUL alternative, but better than sucking down those cigarette carcinogens.
