Do not give other people your prescriptions!
There are both federal and state laws that make using or sharing your prescription drugs illegal. If you take a pill that was prescribed to someone else or give that pill to another person, not only is it against the law, it's extremely dangerous. Doctors write specific prescriptions to remedy your specific condition. A painkiller prescription for your knee surgery is not going to be the same prescription your daughter would get for a jammed finger or toothache.
