How can people tell that you're stoned? (Beta)

I know it's a cliché, but I just laugh for ages and ages.
Like when my friend told this guy to stop making a "commotion" just that word made me crack up for about 10 minutes non-stop

Both red eye and squint eye give it away for me, especially as i wear glasses which makes it more noticeable. Both played a part in me losing my job lol.
