Start smoking cigarettes (and pot) with your son. Kids are naturally rebellious, so he'll like that aspect, plus, he won't feel left out when you light up around him. You should tell him that, no, cigarettes aren't good for you, they are very unhealthy, but that there's so much other toxic shit in our environment that something's gonna get you sooner or later, even if you didn't smoke, so you might as well. Tell him that cigarettes are legal but pot isn't because the government doesn't like people to think for themselves, they want you to do as you're told. Make sure he realizes that police are NOT his friends, tell him he has much more to fear from government and police than he does from minority groups that live in other parts of town. Make sure he knows that cops carry weapons NOT to protect him or Mommy & Daddy, but in case the cop feels like killing Mommy , Daddy, or little boys just like him. Explain to him him that the amount and kinds of toxic chemicals put into the air by the cars driven to his school by the DARE counselors and cops are far more dangerous than your cigarette smoking is, and that DARE singles out smokers because they are a minority group, making them an easy target. Teach him how drugs and drug users have been scapegoated for many problems in our country, and that the real casue of many social ills is drug prohibition. Above all, teach him that authority is to be questioned, not trusted, and that anything that comes out of a policeman's mouth is a lie.
Buy him a BB gun and some targets that look like uniformed policemen as a rewrd for him once you are sure he understands that he is not to trust the government, police, teachers, or religious institutions, only himself.
