my sister was 49 years old, 5'4" and about 130lbs. She passed away last week. She has smoked meth on and off for about 10-15 years...and in the last year, 4 month after moving into a new residence she had a severe asthma attack and was hospitalized. She has neer had asthma and she continued to have breathing issues though I dont know if she was using at the time when I saw her with labored breathing. She was given inhalers and a nebulizer machine which seemed to help the asthma episodes. She claimed the home she was in had mold and there does seem to be some mold in certain areas though I dont know if it is black mold spores. A couple of weeks ago she collpased and went into cardiac arrest which resulted in brain death. We were told by the people she was with that she was having breathing difficulty and was working herself up just before she went into resp. failure. The Dr. told us she was either having siezures or withdrawl symptoms for the first couple of days during her coma...when the jerking stopped the Dr. claimed it was most likely withdrawls. Does it mean she was smoking meth at the time of her collapse? DId the meth cause her asthma and the asthma attack which caused her to collapse? could it be there was no meth being smoked at the time of her collapse but the labored breathing for a few hours and asthma attack truly caused her collapse? we are trying to figure out what my sister died from...can you help us figure this out?

Thanks
