What is the legal age to smoke a electronic smooth hookah pen. 0% nicotine,

charcole, and tar.? I am wondering because many of my friends from my school in texas smoke the smooth e hookah sticks from smoothcigs and apparently someone told the assistent principle that he had one of the hookah sticks in his backpack. so the ap asked him if he had any "non appropriat" school items and he said yes. so when they searched his bag they found the e hookah and they gave him in school suspention or I.S.S. and they will possibly ticket him. i dont understand how you cab get in that much trouble for having a non lightable stick that despenses water vapor simply by breathing in...i just want to know if this is bull or if there really is something wrong with the e hookah. remember that he didnt use it, he just had it on him.
