Here is more data about why smoking is good for your health.
Presented in parts.
1. Early humans started to smoke because they discovered that if you inhale a drug it will worker faster and do a better job then if you eat or drink the drug. (medical drugs). They used plants and herbs. It can get into the blood system faster via the lungs then going through the digestive system and have a more effective impact. Re: medical pot as apposed to pills containing the same chemicals.
2. Cancer is a name used which is really the deterioration of the nuclear envelopes within cells. Linked to MIDS or Magnetic Deficiency Syndrome.
3. Which is linked to a definciency of a vitamin - re: niacin, that would otherwise prevent the effects of pellagra.
3. Smoke contains the vitamin that can be inhaled that can supply the cells with what they need to off-set nuclear envelope deteriration within the the cells.
So then why do smokers also get cancer?
Well it goes like this. If a farmer ads something to make his crop grow better or faster, it also makes the unwanted weeds grow stronger and faster. therefore the damaged cells get the same "food fuel" as all the healthy cells.
So smoking is helping all the cells get stronger and healthy, without discrimination.
