This term refers to the standardized weed produced by NIDA that was until very recently the only cannabis that could be used in US cannabis research. DEA was in the process of approving new suppliers in 2021, and may now have done so; it is unlikely that many/any studies have yet been published based on the new sources, if any were ever actually approved.
The NIDA "research-grade cannabis" is well known to be of extremely poor quality compared to legal-state commercial, dispensary, or black-market, weed. Sorry to burst your bubble.
I was working with a company out of CA that was being evaluated for this purpose as a recruiter back in 2019, but I'm not sure if that ever came to fruition or still in the works. Last I knew the only producer was Ole Miss, and I just saw they were awarded another 5 years in 23'. As of right now it seems they are still the only producer. Quite unfortunate that they haven't made it happen even after repeated admissions that they need more diversity in product. It makes you wonder why that is.
Why do I care? I just got back my blood work for my annual physical, and there are few troubling areas that I will talk to my doctor about. I'm going down the internet rabbit hole to see if there is a connection between a few items in my results and cannabis use. So far, nothing concrete, but I'm learning good stuff.
I hope you're able to make the necessary changes to turn your health around. Obviously eating well (walked, swam, flew, grew) and consistent sleep schedule will have the biggest impact on your physical health. Being consistent with WHEN you eat and sleep is going to set your body and bodily processes up for success, especially the older you get.
As far as consumption goes, specifically with vaporization, the lower the temp (I suggest 338f, THC is released at 314) the less impact it will have on your lung health. Your source material (obviously need more studies on this) is going to make a difference as well. Keeping down inflammation through diet and temp can make a noticeable difference. CBD can help combat inflammation as well as certain foods.
Edibles are definitely the "healthiest" option of each consumption, but you have to deal with dosing issues and onset timing.
As for using Perplexity, I've been using it more and more for both simple and complex research and coding tasks, and I'm impressed with the results so far. It's a tool, nothing more.
Love to hear you're discovering the benefits of AI's! Definitely check into prompt engineering, but no need to pay for this.. plenty of resources online. Open AI even has their own guide to help with this. The main limitation people will have with LLMs is their ability to communicate clearly what they want from it.
