With all this talk of the legalization of marijuana/cannabis, I'm kind of wondering more about it. How can I best explore that topic?
Before we begin may I please ask if you support or prohibit it's use? 
Thank you for asking! I'm ambivalent. I don't really care all that much. I'm not a user, but I think it should be legalized. So, I guess I do support it.
I find that I agree with you. It's benefits both in the medical and recreational areas are both very positive. I find we are heading in a positive direction.
Is there anything specific you can tell me about it?
Sure. The only negative thing I can think of is that long time usage can cause psychosis. I experienced this first hand one time and that's why I had to quit. It was an nightmare!
Do you have any facts or statistics about it? Or a fun fact you like to tell people?
Absolutely! It causes short term memory lose and really bad anxiety! Oh, and the munchies!
