Red Ribbon Week in Kindergarten

Next week is red ribbon week, the beginning of DARE for my kindergarten son. I really don't think I want him to participate, but I'm too scared to go to the school to tell them I wish to opt-out of the mind-control for my son. I feel like they'll probably hotline me to social services if I do. I don't know if I should talk to my son about this, or pretend like I think it's a positive thing. I fear that he'll go back and tell his DARE officer that his mommy doesn't think DARE is an effective use of tax dollars or drug prevention.
