hey I just searched petition-them.com (the number one petition site in the UK, its been on the news and newspapers quite alot), and i went to their news section and found this -

Legalisation of Cannabis has over 13,000 signatures - a great achievement. This is our top petition and is receiving a steady flow of supporters day by day. Also see some of the press the petition is generating in the US - Click Here.

maybe someone will pay attention eventually? ?
