OP I would suggest low dose edibles. Read the instructions though. An edible chocolate bar for example will often have one small square as a full dose. People screw up and take too many all the time. Plan a time to do it with supportive friends or family and start well below a full dose and work up over the course of days or even weeks. I.e take like, 1/8th of a dose day one. If that does nothing don't take more that day. Wait and take 1/4 of a dose the next day, etc. give at least 12 hours for it to clear your system.
Edibles have a different feel but you might find that it solves the physical anxiety with a very small, cost efficient dose.
This is an issue with cannabis as treatment though, especially as a legal recreational substance. Labeling of THC concentrations has a long way to go to truly facilitate the use case you're looking for without you personally putting a lot of work in.
WTF are you talking about?
Read the article I posted. Are you a neurobiologist?
The study you linked to:
1. Refers to incidence of cannabis use as having used it period, not as a causal factor.
2. Specifically states that the causal relationship has not been explored adequately.
3. References a 31% incidence rate for people with the listed conditions vs. 20% for gen pop, but then does nothing to qualify the likely environmental factors that have a correlative but not causative relation between cannabis use and various mental conditions.
In short it's a paper written by someone who focuses on these kinds of psychosis specifically and is looking for causation around every corner. That is part of scientific research but it shows a lack of understanding how most people with these conditions likely spent years self-medicating. A common oversight of academics the world over.
The fact that you push this as a scientific paper supporting your claim when the paper backs up none of thr claims you are making shows an inherent lack of scientific understanding on your part and nothing more.
