No it's not illegal, I buy them regularly (I'm 16). Parents are against them because they have high amounts of caffeine, which is bad for your heart and can cause high blood pressure. Also it affects sleep patterns and they have much more caffeine than coffee. If you have them rarely, then there's no problem. It's like alcohol with adults. It's not illegal, but binge drinking is discouraged due to health effects.
