Antonyms for the term "recreational drugs" include prescription drugs, over-the-counter medications, natural remedies, and therapeutic drugs. Unlike recreational drugs, prescription drugs are approved by medical professionals to treat specific health conditions and require a doctor's prescription. Over-the-counter medications, on the other hand, are available for purchase without a prescription and are used to alleviate symptoms such as pain, allergies, or colds. Natural remedies, such as herbal supplements or essential oils, can also provide relief for certain ailments. Therapeutic drugs, also known as healing drugs, are used to improve health conditions and are prescribed by medical professionals. Unlike recreational drugs, these substances are designed to promote healing and wellness, rather than recreational enjoyment.
