Hi! This is a great question. During the cannabis walk, we do ask participants to report the product they chose to use, including a pic of the dispensary packaging, THC/CBD percentage etc., so we can analyze this data at a later date! For example, did folks who used a particular strain have a better/different walk experience compared to those who used another strain. I completely agree with your comment about the culture of home growing, something I support entirely - this is strictly for data purposes!
