Getting Xanax next week (Many little Questions)

How much should I get? Ways to consume? How much to consume? How long does it last? How long for it to kick in? Can u crush it up and swallow with water? A brief explanation of it? Chances of it being laced? If your going to awnser any question you don’t need to awnser each just many questions I have before I take Xans. If anyone with experience want to share a common experience they have with Xans that would be helpfull to just so I know what will most likely happen.
