Fair enough, but I would disagree on the point about taking an unknown amount (unless I misunderstood?). In my view correct dosing is one of the best ways to achieve a safe experience. One of the biggest issues with such substances is that most users will have no idea how strong the dose is, or if it is even what it says it is.
Courage is one thing, but overdosing is not a pleasant experience, even if it is usually not (physically) unsafe. Cannabis edibles are famous for this since most people have no idea how strong their brownies even after they make them. It was one of the main reasons I made an online calculator as a side project (http://www.scientificedibles.com) to help people to estimate dosage, rather than "take one" and end up on the floor.
I too wanted to use adSense in order to drive traffic to my side project. I made a small calculator for estimating dosage in cannabis edibles, which gets a few clicks here and there (https://www.scientificedibles.com).
It turns out that adSense, will not touch any cannabis content with a 10ft pole so it pretty much ruled out getting any traffic via them. There were some more niche advertisers but for those you needed substantially more funds.
In the end, I found that SEO and content were a good alternative (and free!).
As a hobby project I made an online calculator for estimating dosage in cannabis edibles (https://www.scientificedibles.com). I found it quite a challenge to get users/feedback initially, however I became active in the edibles subreddits on reddit. I generally try to be contribute to the community, and when I see questions where my site can help I do the calculations for the user, and post them a link to it on my site (I made a sharing feature).
I think this is a fair way of providing value, while also raising awareness of my project. I think you can easily get in trouble if all you want to do is just get users to your site by spamming links, and not put in any effort to understand the community you are engaging with. I would just go with ads instead if that's the case.
