I didn't say harmless. I said has not been shown to be harmful as compared to any assumed baseline, ie: cigarettes cause X, and this should as well.

There are many years of propaganda to fight against.

The question, does the benefits (depends on the goal) outweigh the risks (depends on the delivery system), and what is YOUR goal?

I could easily argue delivery system on any smoking issue, and legal rights VS medical company lockup as compared to an easily home grown MOSTLY harmless medicine when used as directed, just like 99% of the stuff in any herb garden.

How does it compare against home distilling?

What is YOUR goal?
