Adderall is a medication that is primarily used to help individuals with attention deficit hyperactive disorder (ADHD) and is sometimes used to treat narcolepsy [2].

This medication directly impacts the central nervous system (CNS), and is classified as a stimulant. While
Adderall
has proven to assist those with ADHD and narcolepsy, it is classified as a Schedule II controlled substance because the drug presents a risk of abuse and dependence which leads to Adderall withdrawal [2]. The benefits of Adderall can be pretty enticing to neurotypical people because of its potential to increase productivity, focus, and memory. However, these reasons for Adderall use are not approved by the FDA [3].

This blog covers adderall overdose, and addresses the symptoms and risks associated with
adderall withdrawal.

Adderall Addiction and Misuse

The rise of Adderall misuse may be traced back to one of its most popular demographics — the college student. Some surveys reveal that 80% of college-aged adults have used one or several prescription drugs, such as Adderall (or Ritalin and Vyvanse, etc.), without a prescription [4]. Many of these students obtained Adderall via a friend’s prescription or off the black market.

It is worth noting that “black market Adderall” poses significant dangers to its users. It’s estimated as high as 75% of black market drugs are contaminated with fentanyl, which is very deadly [4]. Additionally, drug seizures conducted by law enforcement indicate that approximately 40% of all seized pills containing fentanyl had a lethal dose [1].

Aside from illicit drug abuse — like taking someone else’s Adderall or buying it illegally — other forms of misuse may include:

  • Taking a higher dosage or taking it more often than prescribed
  • Changing the route of consumption (snorting, smoking, or injection)
  • Mixing Adderall with alcohol or other drugs [1]

Additionally, a person’s reasons for taking Adderall may suggest a drug abuse or misuse problem. The following are illegitimate reasons for obtaining a prescription for Adderall:

  • To increase alertness or stay awake
  • To help with concentration (unless diagnosed with ADHD and approved by your doctor)
  • To increase focus for academic purposes
  • Controlling appetite and losing weight
  • Merely to experiment with a new drug
  • To use recreationally and feel a euphoric high [2]

Can You OD on Adderall?

Yes, you can overdose on Adderall, and several factors can increase this risk. Adderall boosts the activity of dopamine and norepinephrine. These chemicals help regulate brain and body functions.

In an overdose, excessive levels of these chemicals can overwhelm the system, disrupting brain function and leading to symptoms like euphoria, anxiety, paranoia, and irritability. Elevated norepinephrine can raise your heart rate and blood pressure, increasing cardiovascular risks.

How Much Adderall Is Too Much Per Day?

What Is a Lethal Dose of Adderall?

While it is difficult to determine the exact amount of Adderall that could lead to a lethal overdose in adults, some studies suggest that doses between 1,400 mg and 1,750 mg may be fatal for someone weighing around 150 pounds [3]. Individuals with lower body weights may face increased risk.

These findings apply specifically to adults and not children. If your child is prescribed Adderall, closely monitor access and dosage, as overdose can be fatal [3].

Adderall Max Dose for Adults

The maximum prescribed dosage of Adderall for adults is typically between 40–60 mg per day. Dosage may vary depending on formulation, weight, and metabolism.

Can You Take 90 Mg of Adderall a Day?

The maximum recommended daily dosage is 60 mg. Never adjust your dosage without medical supervision.
