Which of the following is considered a moderate risk psychoactive drug?

Marijuana is considered a moderate risk psychoactive drug because of its potential effects on cognition, perception, and mental health, along with its relatively lower risk of severe physical dependence compared to other substances. While it can cause impairment and has been associated with negative health outcomes, its risks are generally seen as moderate when compared to substances like heroin, which is associated with high potential for addiction and severe health consequences, and LSD, which, although it can induce intense psychological experiences, is not typically associated with physical dependence. Caffeine, while psychoactive, is considered low risk due to its widespread use and lower potential for addiction or severe health effects. Therefore, marijuana occupies a middle ground in terms of risk profile among commonly used psychoactive substances.
