You should only use CBD oil products if you are willing to accept at least some risk of testing positive on a drug test. Not everyone who uses hemp-derived CBD oil tests positive. But it does happen. The risk of testing positive is lower if you're using a broad spectrum or isolate product. These products have non-detectable levels of THC based on manufacturer testing.
Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.
That said, very little is actually known in regard to the long-term health effects of CBD vape juice. Much more needs to be done in order to learn about the potential respiratory complications (and other health concerns) that may arise further down the road. For the time being, all you can do is know the contents of your CBD e-liquid, know how it was manufactured, and ensure that you buy from a well-known and reliable company.
I’d love to hear how it worked for you! I’m sorry you have renal failure and congestive heart disease, my mom who is 51 has stage 5 renal failure and congestive heart disease as well, I just bought a cartridge with CBD vape oil and want her to try it. But she’s unsure so I’d really love to hear from you how it may have helped you. I hope things get better for you. I take care of my mom and know the daily stress and struggle it can bring. Again I’m sorry to hear you we’re diagnosed with those diseases.
