What type would you like? Do you think doctors would recommend such products and patients would continue to buy such products if they didn't work/help?
Doctors and patients both benefit from the placebo effect - if it solves the problem, great, doctor and patient are happy and continue to do it.
I have health issues no one knows how to treat, and I have had doctors (qualified medical experts with decades of experience) recommend things there was little to no reliable evidence for currently, just in case they worked (didn't for me).
I (and lawmakers - CBD etc. are illegal where I am) want to know if things actually work.
The key here, though, is that formulation contains THC (and extracts from other plants) and is derived from marijuana cannabis plants, instead of just hemp-derived CBD.
