Driving with weed in illegal states is risky. That is why I never drive with more weed than I can eat. I can tell you because I conducted stops first hand. There is a ridiculous number of traffic/drug cops roaming the U.S. highways.
Can you mail your weed?
It's much safer to mail your pot. It is easier and safer than you think. Better yet make a score upon arrival. The chances to be busted by a highway interdiction officer are high. Especially compared with being busted for mailing pot. Or even purchasing small amounts of marijuana for personal use.
Is it better to bring it or buy it?
Like I said above purchasing marijuana after you arrive is safer. The police don't really care about purchasing small amounts. Citizens often get busted selling large quantities of marijuana.
Often during "reversal" stings where police pose as drug dealers to lure in large sums of cash. This does not hold true to purchasers of small amounts of marijuana. Buying small amounts of pot requires very little money. Law enforcement is not interested in reverse stinging for small sums of cash. It is just not worth their time.
Do they sting small people?
Yes, the cops do occasionally sting people buying small amounts. Posing as a dealer, police sell a small amount of contraband to unsuspecting citizens. They later make a traffic stop on the purchaser and seize the small amount and make an arrest. These strings are called, “road-kills.” To avoid a road-kill, never purchase more than you and the occupants can eat.
If visiting a friend, it's safer to mail small amounts of marijuana to your destination before leaving. Or take a look at our article on how to fly with weed. If you are driving use the United States Postal service and not UPS or FedX. The latter two are private companies and are allowed to open any packages without a warrant. U.S.P.S. packages can only be opened with a federal search warrant or by the postmaster general. Small amounts of pot are not alarming to U.S. postal investigators. The grueling process of obtaining a federal search warrant is not worth their effort. Please take a look at this on how to send weed in the mail.
