What drug is most commonly used in the United States after alcohol?

Marijuana is the most commonly used drug in the United States after alcohol, and its prevalence can be attributed to various factors. First, marijuana has been legally accepted in many states for both medical and recreational use, which has significantly increased its visibility and accessibility. The cultural acceptance of marijuana has grown, with many people viewing it as a safer alternative to other recreational drugs, contributing to its widespread use.

Additionally, the effects of marijuana, which include relaxation and a sense of euphoria, attract many individuals seeking a mind-altering experience. Surveys and studies consistently show that a substantial portion of the population has tried marijuana at least once, illustrating its status as a widely used substance. In contrast, other drugs listed, such as MDMA, PCP, and cocaine, have lower user statistics and are often associated with different social stigmas or risks. The combination of legal status, cultural acceptance, and the reported effects of marijuana contributes to its position as the second most commonly used drug following alcohol in the United States.
