Does common use mean a drug is safe?

No, common use does not mean a drug is safe. Some of the most widely used substances, such as alcohol and nicotine, are associated with significant health risks, including addiction, chronic disease, and long-term harm.
Perception of safety is often influenced by legality and familiarity rather than actual risk. Substances that are widely accepted may be underestimated in terms of their potential for harm.
Risk depends on how a drug affects the body and brain, as well as patterns of use, dose, and individual vulnerability—not how commonly it is used.
