Defining a Number 2 Controlled Substance
A number 2 controlled substance, also known as a Schedule II substance, is classified by the federal Controlled Substances Act (CSA) due to its high potential for abuse and the significant risk of developing severe psychological or physical dependence. Unlike Schedule I substances, which have no accepted medical use, Schedule II drugs are prescribed for legitimate medical purposes, but their powerful effects and addictive nature necessitate stringent controls on their distribution and use.
This classification is determined by the DEA based on factors such as the drug's acceptable medical use and its abuse or dependency potential. The strict regulations governing Schedule II medications are designed to minimize the risk of misuse, diversion, and addiction, protecting both individual patients and public welfare.
Examples of Schedule II Substances
Schedule II drugs include a variety of potent medications used to treat specific, often severe, medical conditions. They are grouped into narcotics (opioids), stimulants, and depressants.
Schedule II Narcotics
- Fentanyl: A powerful synthetic opioid used to treat severe pain, especially post-surgery or for chronic pain that is unresponsive to other treatments.
- Oxycodone (OxyContin®, Percocet®): A prescription opioid pain reliever used for moderate to severe pain.
- Hydromorphone (Dilaudid®): An opioid analgesic used to manage severe pain.
- Methadone: An opioid used for both pain management and to treat opioid addiction.
- Morphine: A powerful opioid used to treat severe pain.
- Hydrocodone: A narcotic, often found in combination products (e.g., Vicodin®), for pain relief.
Schedule II Stimulants
- Amphetamine (Adderall®, Dexedrine®): Prescribed to treat Attention-Deficit Hyperactivity Disorder (ADHD) and narcolepsy.
- Methamphetamine (Desoxyn®): Used for ADHD and exogenous obesity (weight loss) under strict medical supervision.
- Methylphenidate (Ritalin®): A central nervous system stimulant for treating ADHD and narcolepsy.
Other Schedule II Substances
- Cocaine: Though also known as a street drug, cocaine has limited medical use as a local anesthetic.
- Pentobarbital: A barbiturate used to treat seizures and induce sleep.
Regulations for Prescribing and Dispensing
The prescribing and dispensing of Schedule II drugs are heavily regulated to prevent abuse and diversion. Key regulations include:
- No refills: Federal law prohibits refills on Schedule II prescriptions. Each new prescription requires a separate visit and evaluation by a healthcare provider. However, a practitioner may issue multiple prescriptions for up to a 90-day supply under certain conditions.
- Prescription requirements: A Schedule II prescription must be written and manually signed by a registered practitioner, or transmitted electronically via Electronic Prescriptions for Controlled Substances (EPCS). In emergency situations, an oral prescription may be allowed, but it must be followed up with a written one within seven days.
- Security measures: Prescriptions may require special security paper depending on state law. In addition, many states require prescribers and pharmacists to check a patient's prescription monitoring program (PMP) history before dispensing these substances.
The Risks of Schedule II Controlled Substances
While effective for their intended medical uses, Schedule II drugs carry substantial risks that require careful management by both healthcare providers and patients. The high potential for abuse can lead to addiction, tolerance, and physical and psychological dependence. Misuse can result in serious health complications, overdose, and even death. Diversion—the transfer of these drugs to individuals for whom they were not prescribed—is also a significant public health issue.
Signs of abuse or misuse include seeking medication from multiple doctors (doctor shopping), unexplained weight changes, changes in behavior or personality, and withdrawal symptoms when not taking the drug. Proper education and adherence to prescribing guidelines are essential for mitigating these risks.
Schedule II vs. Schedule III Drugs
The federal scheduling system categorizes controlled substances based on their potential for abuse and dependence, and accepted medical use. A comparison of Schedule II and Schedule III highlights the greater risks associated with the former.
| Feature | Schedule II (e.g., Fentanyl, Adderall) | Schedule III (e.g., Tylenol with codeine, Ketamine) |
|---|---|---|
| Abuse Potential | High potential for abuse. | Moderate to low potential for abuse compared to Schedule II. |
| Dependence Risk | Abuse can lead to severe psychological or physical dependence. | Abuse may lead to moderate or low physical dependence or high psychological dependence. |
| Accepted Medical Use | Yes, with severe restrictions. | Yes. |
| Refills | Prohibited; each prescription requires a new one. | Up to five refills allowed within a six-month period. |
| Prescription Method | Written, signed, or electronically transmitted (EPCS). Oral only in emergencies. | Written, verbal, or electronic prescriptions are permitted. |

Conclusion
In conclusion, what is a number 2 controlled substance is a classification for medications with a high abuse potential that can cause severe dependence, despite having accepted medical uses. Examples range from potent opioids like fentanyl and oxycodone to stimulants like Adderall. The strict federal and state regulations governing these drugs—including prohibitions on refills and specific prescription requirements—are in place to manage the substantial risks of misuse and diversion. Understanding this classification is vital for healthcare professionals, patients, and the public to ensure safe and responsible medication use.
