So my sister and brother in law have 3 kids one is 16 one is 14 and one is 9. the 16year old came to me when she was 15 (a week or 2 ago) and told me that she smoked pot for the first time with her parents. now the 14 year old says that he wants to do it too. i am so strongly against this its not even funny. my sister has had a very rocky relationship with my mother and i (we r very close and she has jelousy issues) and i dont want my neice to go down the wrong path as i did. my sister got me high for the first time when i was 11 and got into heavier drugs after that. not only that but my sister is president of the pta. should i do/say something?
