Which of the following is considered an illicit drug?

Cannabis is classified as an illicit drug in many jurisdictions due to its psychoactive properties and the potential for abuse. Unlike paracetamol and ibuprofen, both of which are commonly used over-the-counter analgesics, cannabis is often subject to legal restrictions and its use can result in various legal consequences. While there are discussions about medical cannabis in some areas, general recreational usage remains illegal in many places. Amoxicillin is an antibiotic, prescribed for bacterial infections, and is also regulated but not classified as an illicit drug. Thus, the designation of cannabis as an illicit drug highlights the legal and social implications associated with its use compared to common medications.
