So, I've thought about this and the ramifications of reported overdoses and/or deaths linked to a chemical legally available online.
Personally, I feel obligated to remove the label ~or~ decant the contents into a different bottle, and either dump what I don't use, or shelve it away in a remote corner of the garage with a label that says "tire cleaner," or something equally nondescript.
Any event of an OD with a bottle labelled "1, 4 Butanediol, Indiana Chemical LLC" in plain sight will result in a report being filed; once enough of these reports accumulate, it'll be enough to raise a flag to the powers that be who legislate and regulate the sale of such chemicals.
I don't want to see a legitimate company that makes its livelihood (at least partially) on the sale of this chemical negatively impacted; I also don't want other future consumers seeking this out (regardless of intent or purpose) to be penalized by legislation making this Illegal.
The upshot is, whether or not you're serious about CTB, take measures to keep this substance safe and well-concealed to ensure it remains available to others at a later date.
1, 4 B will probably be banned from public sale in the not too distant future, but regardless, I don't want my indifferent attitude to play any potential part in that.
Disguise it; hide it; keep it safe.
