In true Reddit fashion, I just repeated 2hat I heard in the shop. After your comment, I researched toxicology and medical journals. You are correct , humans rarely die from ingestion. However, people taking too much can experience excessive vomiting & diarrhea and bronco constriction. The later is like a severe asthma attack and you end up in the hospital on a ventilator and IV drugs. So, not a death sentence but not benign either.
