I recently went on a guy trip to Reno and the day before the trip, fedex'd a small box to the care of myself at the hotel, noting on the shipping advice that I was a hotel guest checking in the following day. It was waiting for me at check in, no questions asked. I paid cash for the shipment (no trace), and I could have always denied knowledge if something went wrong. That's my advice becuase I had the same concern and it worked like a charm.
This is the best method for sure! every time im going somewhere to visit people who are pot smokers I just mail them however much I need.
I put the weed in an appropriate sized ziplock bag and suck the air out... then I vacuum seal it, and hide it inside the package cleverly and send it off.
When Im going to see people who dont smoke, then I just take edibles/tincture
with the security ramped up from 9/11, plus extra security through the holidays I would definitely not take weed through a security check point. Pre 9/11 i think i heard of someone taking their medical marijuana through security and getting in a bit of trouble, but no tickets of fines. If you have a medical card and you get caught and act totally innocent, and are going to a medical marijuana state, you might get off with a warning, maybe a fine... but no medical card caught at a major airport I think would be bad news! you would without a doubt have half your day wasted, a fine, and maybe they would arrest you, maybe hold you for 24 hours... Doesnt sound worth taking weed through a check point to me!
