You give a friend which you trust your money to buy some good weed for you.
He call you and tell you he got it and will wait for you to come to take it.
As you are on the way to him to take your weed your friend smoked all alone and wont open you the door.
Now you lost your money, your weed and the trust in your friend.
Better buy the weed KYC free P2P and take it home to you where you have full control over it and enjoy it by yourself.
