Which statement is true about Schedule I substances?

Which statement is true about Schedule I substances?

• A. They have medical use.
• B. They are illegal to possess.
• C. They have no medical use in the United States.
• D. They are safe to use recreationally.

Answer: (C)

Schedule I substances are defined as having no accepted medical use in the United States and a high potential for abuse. Because of this designation, the statement that they have no medical use in the United States is true. This status means they are not prescribed or used medically in the U.S., and research on them is tightly controlled. It also explains why they are not considered safe for recreational use. While possession is generally restricted, it isn’t an absolute blanket—except in licensed research or approved programs, possession is not permitted. The other statements clash with the official status: they are not recognized as medical drugs, they are not safely usable for recreational purposes, and any possession outside approved settings is not allowed.
