There is a wide-range of drug crimes that can lead to legal sanctions in the United States. Different types of drugs, both legal and illegal, are classified into schedules by the federal government, and individual states have laws dealing with drug crimes written into their penal codes. Schedule 1 drugs are those that have a high potential for abuse and that have no recognized medical benefit, such as heroin and LSD. Schedule 2 drugs are those that have a high potential for abuse and that are addictive, but that do serve a medical purpose. Schedule 3 drugs are also drugs with a medical purpose, but that have a lower risk and a lower chance of addiction. Schedules 4 and 5 drugs are the least dangerous and addictive. The classification of different drug crimes and penalties is based on factors like the schedule of the drug, the type of drug, and the amount of drug a person has on them at the time of your arrest.
