Step-by-step explanation:
Four legal substances that can be abused include alcohol, nicotine (tobacco products), prescription opioids (such as oxycodone and morphine), and benzodiazepines (like Valium or Xanax). These substances, even though they are legal, can have psychoactive effects that alter mood, perceptions, thinking, and behavior - leading potentially to abuse and addiction.
