Cannabis: "Soft" but hard to stop?

Most people consider it to be a "soft drug" causing short term relaxation and euphoria. However, despite the fact that most cannabis users and most people who smoke will have no long term physical or psychological effects, one in ten will become dependent and three quarters will experience withdrawal symptoms when they stop using.
Cannabis can cause serious harm. Cutting down or stoping can be hard, but this is a great place to start.
