I never did any drugs but when I was growing up, it was understood that you needed to keep your drug use somewhat secret, behind closed doors, hidden from the public, I expected there would be consequences from the police if I decided to do drugs out in the open.
Now I see guys doing extremely hard drugs out in the open on the street and on buses. it is a jarring. They're usually not trying to inject or exhale on me ( though the meth smoke guys on some buses don't seem to care ).
