But plain truth logics get lost in the maze of government rules, policies, statistics and jargon, and succumb to the lobbying power of industry. Government dishes out bulky figures on the jobs and revenues generated by these trades, political fallouts of bans, etc. As for public health or environment, the government fulfills its duty by putting the onus of the perils on the public itself through advices and warnings. Who is bothered of them anyway as long as taxes from such industries are pouring in? Government runs with the hare and hunts with the hounds.
People had better take care of themselves before it is too late, by voluntarily abstaining from these evils. And nothing can help one quit them unless he wants to quit.
