These items are not Cannabis, they are CBD oil which is an entirely different thing. CBD oil does not have any of the chemicals which make you high (THC) but are good for pain control or lessening anxiety. For example, our grandson who is ASD has had really good results for CBD drops when he was younger and now Gummy Bears. His parents tried it in desperation after doing a lot of research because he was so distressed, wouldn't stop shouting at the top of his voice (stimming) and was completely unable to say any words at all. 3 weeks after taking them, his Speech and Language Therapist could not believe the difference in him. They were really thinking that they would have to intervene medically to stop his distress. She was astonished that he started to communicate with her and actually started to repeat short sounds. Whilst he was learning to talk, she was more than happy to advocate that he continue to take it and used him as a case study. His EHCP was changed 3 times with his targets extended because his progress was startling.
His parents no longer use it every day because they don't want him to become so used to taking it all the time even though it is not addictive. It just doesn't work so well. However, if his behaviour starts to become problematic, they use it for a short period of time and always see an improvement.
I tried it for pain but it didn't make much of a difference so I didn't continue with it. My Mum found it really useful but her partner just couldn't get it into his head that it wasn't illegal so he made so much fuss, she gave it up.
It is still illegal to sell cannabis so these items definitely won't be cannabis. Do your research about CBD oil and you might be pleasantly surprised.
