These stimulant medications are prescribed to treat attention deficit disorders and are sometimes used without a prescription. Though relatively safe if taken as prescribed, these medications don’t work for everyone. It may be difficult to tell if a friend is using unless you observe them. One caution: Ritalin can mask the signs of drowsiness and lead to impaired driving.
