No way! it does not make you an idot by any means. someone i am related to smokes and has heart problems, he can get away with it im sure you can. Im feeling like maybe you should just smoke a bowl and relax, i think you might be trying to smoke too much at one time, if your doing it for the pain, there is no need to get so messed up i would think. Hope i could help somewhat, oh, and yes you can smoke again, if you trip one night it dont mean you will the next. (i know that from experiance.)
Happy Smoke and good
luck to you,
