About 0.2% of the US general population has an amphetamine use disorder, and lifetime dependence among ever-users reaches 14.8%. These figures sit beside a treatment and legal framework that includes strict US Schedule II refill limits to a 30-day supply. The article organizes addiction outcomes, health risks, and policy signals to show where harm concentrates and how recovery rates actually perform.
Key Takeaways
- Amphetamine lifetime dependence rate is 14.8% among ever-users per NESARC.
- Amphetamine has a molecular formula of C9H13N and a molecular weight of 135.21 g/mol, existing primarily as a chiral molecule with dextroamphetamine being the more potent enantiomer.
- Chronic amphetamine use causes cardiovascular mortality risk increase of 3-4 fold.
- Amphetamines improve ADHD symptom scores by 25-30% on Connors scale in meta-analyses.
- In 2022, 16.8 million people aged 12+ used prescription stimulants like amphetamines in the past year in the US.
Amphetamine use remains a major concern, with rising health risks highlighted by recent statistics.
