I'm not sure. It's definitely not comfortable, and sometimes the thoughts/delusions are more advanced than phantom physical pain.

My first experience with weed was a couple of years ago, and there was paranoia from the get-go. My dad also got paranoia when he tried it so he stopped.

When I started smoking weed for the first time semi-regularly (~1.5 years ago, 0-4 times per week) I had become "pretty crazy", which consisted of lots of notes, voice memos, and screenshots of the notes and voice memos.

The outright-crazy stuff mostly ended about a couple months after I stopped living in my car, which I had to do because of the and it getting down to -19C at night. Within the past year I haven't been near the deep-end, but my weed use has been off and on between regularly (3-7 times per week), semi-regularly (0-4), and zero. I consistently experience paranoia/psychosis whenever I get high, but it generally isn't harmful, and is sometimes silly. My friends put up with it.

However very recently for 6 days, I lived in a cruel reality that existed in my head. It was caused by a long-term (2 yr) long-distance (6 mnth) codependent girlfriend who can be a capable and stubborn liar. Thankfully the extent of the terrible things I believed happened didn't actually happen–she didn't even make it to cheating on me, let alone the malicious delusions I experienced–and she happened to have suitable proof. If she hadn't I might still be in that reality.

I think the episode was more to do with how she shattered trust, and some coincidental events during the 6 days, but I believe my weed usage helped my brain to create the complex unimaginable scenarios, then experience the pain fully. For a handful of hours in those 6 days I was close to tell-no-one suicide, after a history of suicidal behaviour.

I'm happy to be in this reality as of a little less than 2 weeks ago, I'm also glad that I endured and survived that pain. I've become a lot stronger, more peaceful, and I feel that I have turned many corners with mental illness which I hadn't faced in the past–though perhaps I can credit that to a deeper dive into Buddhism and to the end of the codependency. We were about to restart our warm embrace the day she anchored me to this timeline, but per some timely advice from her friend we took a step back and ended it.

Whether or not the psychosis is temporary, or whether it causes early-onset schizophrenia is an area I'm excited to see more research on. It's definitely not as black-and-white as many people paint it out to be, and talking about any potential downsides of the drug is sometimes met with stigmatism because you're "falling for the propaganda".

One aspect of weed legalization is going to be psychosis in a subset of people who use it, and it's not exactly a safe phenomenon. There were definitely paths during my bouts with weed that don't lead to being here like this today. At the same time I'm grateful for the experiences it has given me, and the lateral thinking it has granted me.

Here's a good article I found, "Pot Can Trigger Psychotic Symptoms For Some, But Do The Effects Last?" [2015]

For Buddhism I've been slowly reading Siddhartha over the past few weeks, and Tales Of Times Now Past off and on over the past year.

I wouldn't generally write such a long, personal comment, but we're neatly away on the second page.
