How long does 72mg of Concerta last in someone whos not adhd?

Concerta, which contains the active ingredient methylphenidate, typically lasts about 10 to 12 hours in individuals with ADHD. In someone without ADHD, the effects may vary, but it can still last around the same duration. However, the intensity and overall effectiveness may differ, potentially leading to a shorter or less pronounced effect. It's important to note that using Concerta without a prescription is not recommended and can have adverse effects.
