Don' worry about it. We hear of new regulations , and there is a big scare, etc. about availability. Fear not.
There's other legal sources of Iodine that are just as effective, that are not impacted by the new regulations, although costing a little more. These alternate source materials cannot be used in the manufacture of illicit substances. If the time arises when they're needed, info regarding the identity and availability of such alternate sources will be published in this forum.
