Adderall is a drug that affects the central nervous system and is prescribed to individuals with attention deficit hyperactivity disorder (ADHD) and/or narcolepsy.[15] This drug is commonly misused by college students as a "study drug," although research suggests that stimulants are more efficient at correcting shortfalls than enhancing performance.[15] Adderall is a highly abused substance among students in higher education because it prevents the reuptake of dopamine, allowing college students to stay up all day or night and remain alert.[15] The effects of recreational use are exhaustion and an accumulation of “sleep debt.”[15] Furthermore, frequent use of adderall during the day and night can lead to sleep deprivation and insomnia.[15]
