I think it is pretty common, if i'm understanding correctly. I used to play Words With Friends or Halo Infinite after i was finished with masturbatory activities on meth or crack, if that's what you mean. I remember my coworker who i used with a couple times would sometimes try to show me random things on his phone but could never find the tab - he'd flip through all the pages with his pointer finger. That was one of those "Dude, stop, they know you're high" situations, but i didn't say anything because he's a grown man and can handle his own shit. He ended up flipping his car on his way to work after not sleeping for a week, fell asleep behind the wheel. Now i am pretty sure he owns a business helping animals though which is really cool.
