The legality of it is something I am not worried about. The reagents to make DMT are not illegal to possess, only DMT itself. I keep them all separated at all times and I do not possess any baggies, scales, or any drug paraphernalia. The drugs are created on-site by me a day before the trip - this is part of the package I offer. Basically you come stay at a gorgeous (sometimes less so but generally nice) home and relax, put your cell phone in an anti-static bag in a safe and unwind before the next day. Sometimes I throw little parties with my friends' bands, but thats at the discretion of the client (after all a party is a good way to attract cops). If I do get caught, I would try my best to use the case as a legal vehicle to change the scheduling of DMT and other psychedelics.
With regards to potions + crystals (the 'pure' form of DMT), well, like other business I offer various products and packages. The trips are different, totally separate categories of mind-altering. Both options are available plus other packages. There's a DMT + LSD two-night stay that I personally think is the most fun (depends on my ability to procure that though, since I'm not that good at synthesis and LSD is legit the hardest drug to make) since they get both the intense "next-level" DMT and then they can ride it out on some low-dosage LSD where we paint, read, write, occasionally program (lots of 'hacker' clients), discuss, and whatever else the client wants to do. I get a lot of couples who just want me to be there to administer the potion and then be "on-call" in case they freak out but that's only happened once. I just write on those days. Working on a fantasy novel.
I have friends who have chronic illnesses who swear by "recreational" drugs such as LSD, DMT (both forms), and, of course, THC. They have good judgement of their limits and I would say are more in touch with their body than able bodied people, it's fascinating to hear them talk of their conception of their physicality as compared to (this is a real quote) the finance bro who sees it more "like a bunch of car parts that evolution glued together". People with illnesses are attuned to their systems in a way that offers a unique perspective to me. However, I have personally never administered a trip to someone who wasn't able-bodied or otherwise 'healthy' - not bc of my preference, it's just been the clientele so far. We generally do not trip with medical people on staff unless requests but that's never come up.
