Which statement is true about illegal drugs and administration?

• A. They are typically pure and dosage is known
• B. Doses are often unknown, and drugs may be adulterated
• C. They do not affect brain chemistry
• D. They have no risk from contaminated needles

Answer: (B)

When considering illegal drugs and how they’re taken, a key point is that doses are often unknown and the drugs may be adulterated. Because these substances come from unregulated sources, there’s no standard purity or labeling, so the amount of active drug can vary widely from one batch to another. Additives or contaminants are common, and a user may unknowingly ingest something stronger or more dangerous than expected. This combination—unclear potency and possible adulterants—greatly increases the risk of overdose and other harm. In contrast, legitimate medications are manufactured with controlled dosing and purification, and injection safety carries risks like infections, which is a separate concern. So the statement that best captures the reality of illegal drug use is that doses are often unknown and drugs may be adulterated.
