Why would anyone say its a sin? Because the government says so? Who the fuck are they?

It's something that grows naturally, and its not any chemical, unless its been fucked with, and shit was added.

I know some of the best God loving people who smoke it, but only at the proper time, such as not when driving, etc.

But of course, if it offends you, by all means follow your heart! It certainly doesn't offend me!
