Get past the fucking base observations and start delving into why marijuana being legal is beneficial, or why marijuana being illegal is not beneficial. Health effects, economic influences, something, ANYTHING
Some of us already did that, but some of you just don't seem to pay any attention to it. No matter how objectively right an argument can be, you will deny it. Why should we bother trying to convince some people that will obviously never change their minds.
If you want to be proven it's good/not bad, you have the whole internet to do your own research, this is a discussion forum in which people share opinions. Google your own shit and stop acting like all marijuana users are irresponsible kids.
Something being natural is a characteristic that does not argue any positive points or negative points. It's a general observation which means absolutely nothing.
Maybe it does argue some points, or maybe you haven't quite grasped the entirerity of nature itself.
