I guess you could say there are some signs to look out for when trying to find a crackhead. The 1st think I look at are the eyes. If they're all wide and big as the fucken moon like this then you're probably on the right path to finding one
Also if their jaw is moving so fast it looks like it's pop, lock and dropping it then you ARE on the right path and will nail that crackhead with your investigations. There are obviously a lot of other signs you could look for but this post would be never ending. So I narrowed it down to the 2 most obvious 1's I thought would be helpful. Thank me later.
