As things stand it is a criminal offence to plant a cannabis seed in
your garden. This situation has arisen as a result of long-term lobbying
by the drug companies. They now aim to channel the medicinal cannabis
market towards the commercial product Sativex, and to make a handsome
profit from it.

If this venture succeeds, it will only be a matter of time before the
pharmaceutical industry uses it's lobby to seek to prohibit the growing
of other medicinal herbs, and, if they can, the sale of seed.

It might be a good idea to lay some in now.
