We did that with alcohol. It didn&#x27;t work out.<p>I hate to be that guy, but the effects of second-hand smoke studies happened long enough after this all got sufficiently politicized to where I&#x27;ll (conveniently) take them at face value, but I&#x27;ll never completely trust them.

By the time the information gets to lunkheads like me, it&#x27;s hash.
