our daughter was diagnosed with thyroiditis, and her blood results had shown, hyperthyroid with tsh levels less than 0.03. Her recent blood test showed T3, T4 levels within the normal range and her tsh had jumped to 1.1. WE wondered what had happened, she had the change occur within a 4 week time frame. She just admitted to us, she had been using pot, occasionally. WE are concerned, but wonder. Help
