The tobacco industry?

Where you going to find the €2 billion a year to deal with the legacy of smoking if you shift things to the black market?

That's what we need, more opportunities for organised crime to profit and grow their empires.

We should be removing markets that these evil parasites exploit to undermine and destroy people and communities not look for more ways to help them out.

When will it get through the thick skulls of western governments that prohibition does not work, it didn't work for alcohol other than to turn small time Italian crooks into international crime syndicates. That is chickenfeed in comparison to the war on drugs that has allowed illiterate South American thugs become trillionaires who have destroyed the lives of millions of people and turned whole countries into criminal enterprises.

In our own country most of the violent crime is being committed by sub human scum who are making huge amounts of money because of the open goal of having an array of "controlled substances" which they can corner the market on supplying. The trade in cheap fags is already bad enough, just imagine how much more they would be making if the stuff was illegal.

Not to mention the utter futility of trying to police and punish people for ingesting certain substances, nowhere in the history of humanity has it been possible to stop people getting high or addicted, we need to grow the fuk up and accept it as part of life and stop making laws based on some stupid fantasy that the use of these substances will stop because they have been labelled as illegal.
