Here’s another option:
Valid if the majority in a given state allow, but patently unconstitutional for the feds who have been delegated NO constitutional authority to meddle with drug use at all.
Was in Singapore for a couple months a while back. The law is the law and they enforce it like they mean it. Even littering will land you in front of a judge. Borderline authoritarian, but one of the very lowest crime rates in the world.
And in regards to littering, it is hands down one of the cleanest major cities I’ve ever seen.
When I worked around SE Asia in the 90s I loved Singapore for the order, cleanliness and safety. I always got nervous though when entering the country because of the drug penalty of death... they mean it... every word. My fear was being planted unwillingly and unwittingly as a mule coming in from a country in the region. It happened to some but fortunately not me. In all my travels I never checked luggage no matter how long I was going to be on the road and kept an eye on my stuff all the time. One large soft side expandable briefcase and one faithful rectangular roll-on. Sometimes awkward, sometimes irritating but always an advantage to me. Business class seating facilitated my travel style.
