I tried different tinctures, and vaping, mostly high cbd, low thc in various dosages over the course of a couple months. I also felt memory effects....I would have a thought, turn around and it would be gone! I realize it is very effective for some of us. That’s why I tried it. That’s ok. I have a pretty good regime of drugs, body work, diet and light exercise that seem to keep me going 😀. Thanks for asking.
