As long as it isn't mandatory (Score 3, Insightful)

If people want to "vaccinate" themselves from drugs that they deem harmful, that's fine by me. However, even though I choose to abstain from drug use, I'd definitely not want to vaccinate myself. By vaccinating yourself, you're basically saything that your will is too weak to be able to avoid these 'vices'. And that might be fine for some people. As long as parents don't start vaccinating their children before they kids can think for themselves, and schools public schools don't require them alongside the other vaccines.
