I almost didn't want to even put this out there, but I don't see the act of smoking weed as a sin in it's self. I agree with Daniel up there though and still very much think it can be abused though. I think it is 100% natural plant, and God told us we could enjoy all the fruit of the earth. You don't have to "make" it, or add chemicals or anything like that, it just grows. In the way I've been lead to look at it now, I feel Romans 14:22-23 covers it as well. If you think it's a sin then it is, but I don't feel it is, so am I just wrong? I also understand that the inhalation of super heated smoke can be considered hurting the temple, but even if that is the case would eating it be better then?
Just to be super clear, this is what "I" feel the Lord has lead me to believe on this subject so far. I am not saying that my view will never change, or that any other Christian should go by what I say (of course), but I do take obedience to God very seriously and didn't just make up my own view without much thinking and prayer and going to scripture. That being said I also agree with everyone above as well. If you feel it's not good for you, then it's not good. It also really helps with the pain in my flail arm now, so I have a mental justification in my head on top of everything else that may be a bias on my part, and I've smoked every day since I was 15, so I am also not trying to pretend that the pain is the ONLY reason I smoke, Honestly I'm sure I'd be smoking anyway. I am curious what other believers will think about my position on this particular matter.
One last thing I'd like to add, the way it effects me now and at the time of my regeneration, is very much different then it did when I started smoking at a young age. My point is back then it did effect me in a much more negative way, I would get tired, lazy, uncaring. So my view is a lot more personal than what most on the outside looking in would see or think, so I'm not saying I feel it's right for everyone out there, just me personally.
