Why has the Government spent public money on making an anti-cannabis advert when there can be no better exposure of the dangers of this vile drug than the 1930s American film Reefer Madness?

As this film is now in the public domain, it would have cost nothing to have it shown on television.

I would suggest that all concerned parents see this film – and make sure their children see it too.

If it saved just one child it would be worth it.
