Self inflicted symptoms of autism from drug use

This may sound like a troll post but it's not.

When I would get high by myself, no matter the drug, I used to find it satisfying and almost fun to make autistic sounds voluntarily, like random grunts or noises or weird patterns. I'd also enjoyed twitching my eye and making crazy shakes. I used to envision that's what autism felt like and it was comedic to me (tho not in a mean spirited way, more like funny to myself to make these noises). I also felt like I could create this cringy but enjoyable euphoria from it lol.

But lately from doing it so much they become more involuntary and sometimes I catch myself doing it and finding it harder to stop. It almost feels like tourettes because sometimes I really have to restrain myself if I do it for a long period of time

I never do it around people cause it's kinda cringe and they'd think I'm being rude or mocking , and it's not taking over my life but I wonder why I still get an urge to do this
