The only bad place to be high is inside a plastic bag, I don't like taking tests high, but its managable. There's some places I love to be high and some places I dislike, but theres no REAL bad place to be high. When your in a holding cell inside the police station the only way to deal with it is to be high.
Places not to go high? Anywhere if you have any of that creepy shit where you are scared of everything.
