If you pass the occasional pill to your friends, you are not alone. According to a recent study published in The Journal of Women’s Health, sharing prescription drugs is common among young adults, especially 18- to 44-year-old women. The recent survey of 25,000 people found that more than one-third of the women polled shared prescription drugs with friends or took pills from their pals. The drugs included everything from allergy meds to pain pills. I'm definitely guilty of offering the occasional Allegra to friends who also take the drug, but how about you?
