I'm glad
dark_prinny is here to set the record straight, man! Oh wait, they are spouting mostly bullshit? Yep.
Okay, let's just start off here that perhaps the OP's therapist/docs know more than you do, rando from ResetEra? And that weed is commonly prescribed for anxiety. And also autism, as the OP does state they are on the spectrum.
Fun facts:
Medical marijuana is legal where I live (Pennsylvania).
I suffer from General Anxiety Disorder and Panic Disorder (yay anxiety! And also depression).
My partner is autistic and suffers from PTSD.
Both of us had gotten recommendations/prescriptions to use marijuana as treatment (me for anxiety, her for autism & PTSD) from the following professionals: trusted family doctor I've been seeing for over a decade, psychiatrist at local well-rated mental health facility, therapist at same facility (though they couldn't prescribe it, just a general "yeah this is probably a good fit for you), etc.
Here, let's look at a small snippet from the PA Medical Marijuana page, just in case this is confusing:
Oh hey, look at that. Anxiety AND autism. Interesting. Must be bullshit.
For my partner in particular, weed is such a life-changer and allows her to work and function much better than she can otherwise.
I do have some relevant info and experience for the OP, as what they are describing is soooo similar to how I felt when I first started smoking (and no longer feel now). But I imma just PM them, as this thread is such a dumpster fire.
Obviously yes, marijuana isn't without potential side effects or complications, users should monitor their intake and how and what they are using it for, it's not for EVERYONE, you can become psychologically dependent upon it (like with anything that makes you feel better), more research is needed, etc. These are a given and should be paid attention to. But it's a fucking life-saver for those who need it and can also be amazing for those who "don't".
I apologize in advance for this post, as I am being a little hostile. I feel it's necessary to combat the bullshit and misinformation in this thread, though.
