Drug smuggeling

There is a constant struggle between the guard and inmates to keep drugs out of prison.  Unfortionatly however drugs still make their way into prisons right in front of cameras and even before the eyes of guards without them even knowing about it.  Sadly enough there are also prison guards and administration that sneak drugs into prison walls for inmates for certain exchanges.  Prisoners offer money, drugs, as well as protection for prison guards who offer to smuggle drugs into prisons.  This has lead to many problems with prisons and the states don't know how to keep the corruption out of prisons when their own men are in on much of the crime and drug trafficking that is happening.  Drugs also get into prisons through visitors who smuggle them in through letters, post cards, hide them under their clothes, and also sneak them in by putting the drugs in their rectums.  There are so many stratigic moves that prisoners as well as officers and visitors have of getting drugs into prisons.  With the process being so easy and the rewards being so high prisoners have no reason to stop.
