The opening scene to Apollo 13 (1995) features a party in Houston with NASA dudes as they gather around the television and Walter Cronkite announces as Neil Armstrong takes his first step on the moon. ( On YouTube )
I was not at that party, but I was at a party in Houston with NASA dudes as we watched the very first moon landing. My dad was a mission control guy with the black horn-rimmed glasses, white shirt and black tie, but Apollo 12, not 11 (Neil Armstrong) or 13 (the one that blew up and barely made it home).
I couldn’t walk yet, and I got that the space man on the screen was super important, but at the time I was missing a whole lot of context. The blanks would fill in with time, since the US was super proud of that moment. It’s my very first memory.
Common cheap field drug tests commonly react to (yield substance-positive results) to other substances such as powdered sugar, human ashes, some foodstuffs and plastics.
Normally an additional sample is supposed to be sent to a lab for more specific results, but the courts in most states accept the field tests as definitive. A positive result is definitely probable cause, which allows officers to search your vehicle or home and take your money and solvent assets, as per asset forfeiture.
But yes, you can expect common substances to be grounds for a drug trafficking charge. Is an execution summary (id est, on sight)?
