Jones went on to define the five schedules of drugs, which breaks them down according to their therapeutic value and rate of addiction. The schedules are
Schedule I: drugs with no currently accepted medical use and a high potential for abuse. Schedule I drugs are the most dangerous drugs of all the drug schedules with potentially severe psychological or physical dependence. Examples of Schedule I drugs are: heroin, lysergic acid diethylamide (LSD), marijuana (cannabis), 3,4-methylenedioxymethamphetamine (ecstasy), methaqualone and peyote
Schedule II: Drugs with a high potential for abuse, less abuse potential than Schedule I drugs, with use potentially leading to severe psychological or physical dependence. These drugs are also considered dangerous. Examples of Schedule II drugs are: cocaine, methamphetamine, methadone, hydromorphone (Dilaudid), meperidine (Demerol), oxycodone (OxyContin), fentanyl, Dexedrine, Adderall and Ritalin
Schedule III: Drugs with a moderate to low potential for physical and psychological dependence. Schedule III drugs abuse potential is less than Schedule I and Schedule II drugs but more than Schedule IV. Examples of Schedule III drugs are: Combination products with less than 15 milligrams of hydrocodone per dosage unit (Vicodin), Products containing less than 90 milligrams of codeine per dosage unit (Tylenol with codeine), ketamine, anabolic steroids and testosterone
Schedule IV: Drugs with a low potential for abuse and low risk of dependence. Examples of Schedule IV drugs are: Xanax, Soma, Darvon, Darvocet, Valium, Activan, Talwin and Ambien
Schedule V: Drugs with lower potential for abuse than Schedule IV and consist of preparations containing limited quantities of certain narcotics. Schedule V drugs are generally used for antidiarrheal, antitussive and analgesic purposes. Examples of Schedule V drugs are: cough preparations with less than 200 milligrams of codeine or per 100 milliliters (Robitussin AC), Lomotil, Motofen, Lyrica and Parepectolin.
Legend drugs could fall within any of the Schedule II through V categories and may carry a sentence of five years in prison, with or without hard labor and a fine of not more than $5,000.
