Cannabis Use Is a Sin?

CANNABIS AND CHRISTIANITY

Kind of reminds me of the term self-righteousness but imagine how much more sinful that must make me! God must just puke at the mere sight of me!

How can any man know this much about God? How can it be this sinful to wish to experience what this man claims God has dulled our minds to in order to protect us?
