I kinda know what you mean. My x best friend (one of my best friends) was a huge stoner. He pretty much got me into it. Anyways on my birthday i had him over and he brought some weed with him. At about 2 a.m. me and him went upstairs to my room(my parents have a bedroom on the first floor) and we had about 3 cigs. Then we threw the cigs in the toilet for some idiotic reason. We then smoked weed got high ate cake and forgot about the cigs in the toilet and fell asleep. We woke up and went downstairs and had breakfast and just hung out with some of my other friends who were there. Anyways about 1 o clock my dad went upstairs to his office and when he went to use the bathroom he found the cigs. He came downstairs and was mad at me. Anyways me and my friend were paranoid. After everyone left i had a long talk with both parents about why not to smoke cigarettes and that stuff. Any ways i told my mom that it was me and then i told her which one of my friends it was after she promised not to tell anyone. My friend was freaked out cause his mom sorta knows he does weed and smokes cigs and she said she would have him take a urine analysis test (shes a nurse and works at the hospital). I told one of my other friends i told my mom and eventually it got to my friend who i smoked the cigs and weed with. He was so paranoid that he cut me off and said he fucking hated me cause i told my mom it was him and he thought she was gonna tell his parents (my mom never told his parents) he still hates me and we arent friends anymore. It pisses me off cause at first i felt like i was being an asshole but now i realize he is because he cant forgive me. Anyways thats kinda how smoking made me lose one of my friends. I no longer smoke cigarettes but i do smoke weed whenever i can.
