Almost every denomination and sect of Christianity believes it is wrong to use cannabis. For some reason they always quote Scripture that pertains to alcohol as reasons for why one should not use it. Why do Rastafarians believe it is okay to use cannabis?

Do Rastafarians believe that Jesus is the way to God in the same way that Christians believe? I find that their singing speaks a lot about God and spiritual matters.

I am a Baptist and I have no desire to call myself a Rasta but I believe in some things they believe in such as living clean, peace, unity, etc. Is it wrong to identify with those things? Many say that Rastafarianism isn't a religion but more a way of life. Would any of their practices (excluding calling Haile Selassie god) be considered sinful by a Baptist congregation?
