If I can use an argument that if you accept the flow of logic to prove that Heroin is a safe and effective way to prevent disease, then you will probably have to understand there is something wrong with the argument
- Premise 1: Vaccines are Safe and Effective
- Premise 2: We add Heroin to the definition of Vaccine
- Conclusion: Heroin is safe, because it's a vaccine.
What if I told you how polio used to be such a big problem, therefore you should take heroin? The no-coiners will go to step 3, without even recognizing they are taking some dubious steps in their reasoning.
