The problem with benzos is their quick tolerance buildup. Even if someone takes them as prescribed, their body quickly builds up a tolerance and they need more and more of the drug to feel the same effects. This leads to the prescription running out quicker and people looking on the streets for the drug. Even those who are not prescribed the drug begin looking on the street for the drug, in hopes to feel the calmness they provide or get a quick high.
In certain situations, this type of drug works miracles and really helps you out, but they are terrible for long-term use. Even if they are taken as prescribed, they are one of the most difficult drugs to come off of and you can actually die from the withdraw effects. Many times other drugs must be prescribed in order for the person to remain stable during the withdraw process. Doctors are beginning to crack down on prescribing them because of this abuse, but I just worry because it seems this new crackdown will limit the availability of the drugs to those who actually need them.
