Maybe this works on a long enough timeline, but by your analogy entire generations of our population are now hopelessly addicted to this particular psychoactive agent. We might be able to make a new generation that is immune to it, but in the mean time these people are strongly influencing policy, culture, and society in ways that are directly based on that addiction. This is a 'planting trees I know I will never feel the shade of' situation.
