What Factors Can Affect The Lethal Potential Of Adderall?
The amount of Adderall it takes for its use to become lethal can vary widely depending on a number of factors.
This means the lethal dose of Adderall won’t be the same for everyone.
Factors that can influence the lethal dose of Adderall include:
- Age: Children and elderly adults will be more susceptible to overdose in smaller amounts.
- Tolerance: People who are Adderall-tolerant will be able to tolerate higher doses of Adderall than the average person.
- Polydrug use: The use of multiple drugs, including alcohol, can increase the risk of drug overdose.
- Overall health: Certain health conditions, including impaired kidney or liver function, may increase the risk of serious overdose.
- Method of use: Crushing or chewing tablets can increase the likelihood of experiencing negative side effects from Adderall use, including overdose.
- Body mass: Low body weight can make a person more vulnerable to drug overdose.
