okay, i'm gonna weigh in here, and give you why not to ship weed...first a personal experience, my best friend was a big dealer in my area, so he started shipping weed, he worked for ups so he knew what the packages go through, he taped the crap out of the box and sealed it put the weed inside something else and taped that shut and everything, shipped a lb. 3 or 4 times,until the package got stepped on and crushed and delayed and sat in a loaded trailer over a weekend, the smell proof bag got popped and the smell gave it away, what you don't know is that ups not only has alot of untrustworthy people working there...i'm one of them, we steal everything because it's all insured, candy, dvds, electronics, watches, jewelry...i seriously pay my rent with schwag...we randomly check boxes to see if there is anything good, believe me if we ever found your stuff, you'd never find it or the police would come looking for you...another problem, we are lazy, we through small light boxes like footballs, we use heavy boxes as foot stools, and we regularly walk and step on packages, i don't think twice when i step on a small box and it breaks. we are also VERY good at making packages like they did when we picked them up, if a package takes too many bumps and looks beat up, they can and they will repackage your package...they are completly allowed to do this and are completly allowed to notify the police if they find anything...
you can get away with shipping weed, just don't make a habit of it, there are too many factors you don't know about
