personally im pretty sure that vaping is safer then cigarettes but i would like to know where i can find a documented study. i have a friend of mine that i work with part time. he is an electrician and i work as his helper. he is constantly ridding my .... about my vaping, he likes to say that "i dont know what vaping is doing to me". i would like to show him that the health risks while they exist are minimal. i would like to be able to vape in peace, i find the critism annoying and unproductive. any ideas??? i like working with him but he should leave the vaping alone
