Can I safely reuse these glass bottles?

I want to reuse these lovely green glass oil-dropper bottles for various herbal remedies, especially comfrey-infused olive oil, but they were originally used for full-spectrum hemp oil. (To any dear beloved narcs reading, I got them empty from a friend who uses them legally for a medical condition.)

Would it in your liability-free opinion be paranoid to worry that there are traces of thc in the bottles after I wash them with very hot water and Seventh-Generation (greywater-safe) dish soap? (Assume that I don’t want any thc in my comfrey oil)

First and foremost, thank you for posting this in the cider press!

The 'good stuff' is suspended in the oil. I wouldn't be concerned that you would have much if any residue if you are thorough in cleaning out the glass bottle. Glass is a nice container substance because it doesn't have pores that some plastic containers might have.

If you washed and dried really well, my risk tolerance wouldn't blink twice.

You might want to consider a high-proof alcohol/isopropyl  soak/rinse before you wash it to ensure it is super duper clean.

Yes to re-using those bottles.  After a good wash, I would use another rinse with alcohol, plus the glass dropper and bulb.

I have done the same many, many times.


Peace
