sorry if this is a tired topic; i've searched the forums for a little bit without finding an answer. i sing and write songs as a hobby, and usually smoke up once every few months mainly to spark inspiration and creativity. i'm not really an experienced smoker. i sing quite well while baked, and i really have the time of my life. however, two weeks ago, i took three bong hits a night, every other night, three times in one week. after that week i noticed that my vibrato isn't as tight and i have less control over the higher notes in my chest register that i gained recently through self training in the last year. i haven't smoked since that week. are there any serious singers out there who've experienced the same thing? i just want to know if the effects are permanent, or if and when i'll get full control of my voice back. also, would a vaporizer eliminate the stress that smoking marijuana causes on the vocal cords? i really don't want to part with the inspirational moments mj brings!
