This is for people age 40+ without Parkinsons, or 30+ with a diagnosis.
Michael J. Fox has been advertising this on Instagram as part of his Parkinsons research. After signing up and answering basic questions about yourself you will get a package in the mail. This has a pencil and 4 booklets each with 10 scratch and sniff multiple choice questions. You log back into the website and enter the data as you scratch and sniff each page. Trust me when I say many of these questions are very pertinent to whether or not you are identifying the same smells as other cannabis breeders.
I don't want to give away any of the choices because that would influence other people. Let's just say a broad range is covered and you would do yourself some good to see how you interpret them. Worst case scenario you spent some time and helped medical research only to realize you get confused by certain scents. The test only took me thirty minutes.
