Let's see...smoking is legal. Maybe I can start "Planned Pulmonary" and get 180 people hooked on cigarettes for every one I help quit. Or "Planned Sobriety" and create some alcoholics with tax dollars!
You'll make billions! Just think of the interesting Mothers Day and Fathers Day cards you can sell, celebrating the addictions and disease and abuses and deaths these wondrous products of culture provide. You'd have to go a long way thought to top the PP-hood x-mas (read Christmas) cards.
