Which schedule can cause severe physical and mental addiction?

Schedule II substances are classified as having a high potential for abuse, which may lead to severe physical or psychological dependence. This category includes various narcotics and stimulants, such as oxycodone, morphine, and methamphetamine. These drugs are often prescribed for pain management or attention deficit hyperactivity disorder (ADHD) but come with a risk for significant addiction.

The justification for this classification stems from their pharmacological properties, which can produce strong euphoric effects, making them particularly prone to misuse. As a result, healthcare providers must closely monitor their use and prescribe them with caution due to these risks.

In contrast, the other schedules—III, IV, and V—contain substances with a lower potential for addiction and are therefore classified as having less severe risks in terms of physical and mental dependence. Schedule III drugs, like anabolic steroids and certain pain medications, present a moderate potential for abuse, while Schedule IV substances, including benzodiazepines, and Schedule V drugs, typically used for cough suppression, have progressively lower risks associated with addiction.
