Political parties do not necessarily insist that their candidates agree with every policy and the legal status of cannabis possession, cultivation and supply is one of those policies: hence Peter Lilley, Conservative, supports legalisation as does Paul Flynn, Labour, and others, despite the prohibition stance of their Parties. Likewise I have spoken to Lib Dems and Green Party candidates in the past who were against legalisation.
That said, many MP's and candidates will say they support "legalisation for medical use" without really explaining what they mean, being seemingly happy to see other victimless users and growers face fine, prison and criminal records.
Some, the dumbest of all, even continue to deny that cannabis itself has any medicinal value: that is how our governments have classified the plant in the Misuse of Drugs Act and theycontinue to deny medical benefits even despite Sativex THC and CBD products are now classified as having medicinal uses and all the evidence, anedotal or not, to the contrary!
THAT IS WHY it is essential for everyone to ask (write, telephone, attend Hustings, emai, whatever) for their personal view and how they would vote (Whip or not) on a bill to fully legalise cannabis possession, cultivation and supply.
OTHERWISE, personally, I could not possibly vote for any candidate either dumb enough or stubborn enough, who stands against legalisation and / or ignores the punishment of victimless consumers.
That is WHY I am ASKING YOU to ASK THE CANDIDATES.
