Third generation pills

One of the unfortunate realities of Ritalin use has been its propensity for abuse. A number of studies have revealed that grade-schoolers have obtained the drug from their peers who are undergoing therapy for ADHD. In one study published in 2001, 651 students aged 11-18 from Wisconsin and Minnesota were focused on. The researchers found that more than a third of the students who took ADHD medication said they had been asked to sell or trade their drugs. Users have crushed the pills and snorted the powder in order to get a cocaine-like rush. It is hoped that newer-generation products, e.g., time-release medications, will be less prone to this abuse since their formulation makes them more difficult to crush.
