Both Adderall and Vyvanse are central nervous system (CNS) stimulants that are prescribed to treat ADHD. While they share many similarities, there are some key differences that are important to know, including their potential for abuse and addiction.

Key takeaways:

  • Adderall is a Schedule II substance under the Controlled Substance Act (CSA), meaning it has a medical benefit and holds the potential for abuse and addiction.

  • The two drugs produce similar side effects owing to their amphetamine properties and interaction with brain function.

  • Both drugs are available under prescription and can be picked up in most drug stores.

Potential for abuse & addiction

As with most CNS stimulants, both Adderall and Vyvanse can lead to physical dependence and addiction if abused.

Adderall addiction and abuse

Adderall has been used since the 1960s as a treatment for ADHD and other behavioral disorders. It has also been abused for its side effects of hightened focus, attention, mild euphoria, and reduced tiredness. 

Adderall affects the central nervous system (CNS) and produces neurochemical reactions such as dopamine production. If Adderall is abused in higher than recommended doses or over a long period of time, the brain can become rewired to its effects, in turn building a tolerance to the substance. This can in turn lead to physical dependence and eventually addiction. 

Signs of Adderall addiction include:

  • Mood swings

  • Overwhelming anxiety/panic attacks

  • Uncontrollable crying

  • Short-term memory loss

  • Intense cravings

  • Depression

  • Adderall withdrawal symptoms

Vyvanse addiction and abuse

As with Adderall, Vyvanse is often widely abused for its ability to improve focus and attention, especially among students and young adults. It is also used as an appetite suppressant for those looking to lose weight, even if they have not been prescribed it. 

Long-term abuse of Vyvanse can lead to a tolerance to the substance forming and eventually physical dependence, the negative consequences of which can lead to addiction. Someone experiencing Vyvance addiction may possess some of the following attributes:

  • Poor sleeping habits at night

  • Unease

  • A lack of coordination

  • Body shakes

  • Skin redness

  • Abdominal pains

  • An unusually inflated sense of self

  • A noticeable change in personality

  • Vyvanse withdrawal symptoms

Luckily, there are addiction rehab facilities across the country that can help those affected overcome addiction.
