writes No. It is neither organic, nor legal. Are you using the word "organic" in the sense of Organic(TM)? It is assuredly (a) organic in the chemical sense, (b) organic in the sense that it is a natural plant extract, (c) organic in the sense that it is ecologically almost harmless and probably organic in other senses, too. Noted. -- Alan & Joan Gould - North Lincs. |

Nicotine is extremely poisonous, and it is very easy to take a fatal overdose if you extract it from tobacco. A large fraction of the usual garden plants (the majority?), not counting the vegetable garden, is poisonous. I don't go around eating and drinking extracts from them, and I see no reason why they should be banned. [Franz Heymann] |

Actually a minority, and there is little difference between the flower and vegetable gardens. The main reason for banning such things is that bureaucrats don't like uppity peasants.

Would you like to propose your hypothesis, so that we can all have a good laugh? Please remember that, in science, a hypothesis must fit the facts to be worth taking seriously.

In this group references to 'organic' are assumed to be about organic gardening practices unless otherwise indicated.

It is the by products of setting light to it, and all the other chemicals that have been added, that cause the problems. Nicotine is a remarkably deadly poison! You can just about extract LD50 for humans from a couple of cigarettes using the right solvents. What protects smokers is that burning is a very inefficient way to absorb it. And addict patches contain only tiny amounts of the active ingredient. As an insecticide it also had the annoying problem of frequently being contaminated with tobacco mosaic virus. And despite it's name the TMV is rather promiscuous about the plants it will infect. In the days when nicotine was still licenced for greenhouse use it caused serious operator casualties. Mistakes with nicotine extract could be severely punished because of its high mammalian toxicity and skin penetration. Regards, -- Martin Brown |

At last someone has said it straight out in this ng. Folk should realise that it is quite silly to use the term "organic" versus "inorganic" in the contexts in which they are commonly used in agri- and horticulture. The more sensible dichotomy is between *beneficient* and *deleterious* substances. Both "organic" and "inorganic" substances in use in horticulture have examples in both camps. If a chemical does a lot of good and a minimum of harm, I will gladly use it, whether it is correctly or incorrectly classified as "organic" or "inorganic". [Franz Heymann] |

The sentence to which you are objecting is quite strictly correct. Some usages of words we have to accept according to context. This is a gardening group. Gardeners should realise that they frequently get their knickers in a twist through the misuse of terms which have prior definitions differing from those they *think* are correct. It has, for instance, occurred in this very thread. "Organic" itself is a case in point. There is a great tendency to call "beneficient" chemicals "organic" and others "inorganic". I have just rechecked the definition of the term "organic" in the Penguin Dictionary of Chemistry.

According to them the Organic Food Industry have a large book full of approved alternative natural chemicals. Copper was the alternative thing to put on potatoes. -- Martin |

Gardeners should realise that they frequently get their knickers in a twist It seems that you're the one with twisted knickers. We all know what's meant without being pedantic. I have just rechecked the definition of the term "organic" in the Penguin Dictionary of Chemistry. ".........Organic chemistry is now the study of the compounds of carbon, whether they be isolated from natural sources or synthesised in the laboratory.........." As a one-time organic chemist I know that. You shouldn't make assumptions. Mary [Franz Heymann] |
