Caffeine is a central nervous system stimulant that belongs to a class of compounds known as xanthines. It is naturally found in coffee beans, tea leaves, and cacao pods, and is widely consumed for its ability to enhance alertness and reduce fatigue. Caffeine works by blocking the action of adenosine, a neurotransmitter that promotes sleep and relaxation, leading to increased levels of other neurotransmitters like dopamine and norepinephrine. While moderate caffeine consumption is generally considered safe for most people, excessive intake can lead to side effects such as insomnia, jitteriness, and increased heart rate.

Adderall is a prescription medication that combines two stimulant drugs, amphetamine and dextroamphetamine, and is primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. It works by increasing the levels of certain neurotransmitters in the brain, particularly dopamine and norepinephrine, which help improve focus, attention, and impulse control. Adderall is classified as a Schedule II controlled substance due to its potential for abuse and dependence. While effective for many individuals, it can also cause side effects such as insomnia, anxiety, and increased heart rate, especially if misused.
