Which substances are considered the most commonly abused stimulants?

The identification of amphetamines and methamphetamines as the most commonly abused stimulants is grounded in their widespread misuse and potential for addiction. Both substances are known to significantly elevate mood, increase energy levels, and enhance concentration, which makes them appealing for individuals looking to improve performance or cope with fatigue.

Amphetamines are often prescribed for conditions like ADHD and narcolepsy, but their euphoric effects can lead to misuse for recreational purposes. Methamphetamines, a more potent form of amphetamines, are particularly notorious for their addictive properties and are often associated with severe cognitive and physical health consequences.

While other substances like caffeine and nicotine are also stimulants, they do not carry the same level of abuse potential as amphetamines and methamphetamines. On the other hand, alcohol and marijuana are classified as depressants rather than stimulants, and while prescription medications can include a range of substances, the question specifically seeks the primary stimulants commonly abused, making amphetamines and methamphetamines the most relevant answer.
