  • I wasn’t presenting Mythbusters as rigorous science, simply pointing out that a false positive is possible when using the tests as directed. If you want hard science, just go to Mayo Clinic’s practical guide for clinicians:

    Opiate screening cutoff levels for DHHS were changed from 300 ng/mL to 2000 ng/mL of morphine in December 1998 to avoid false-positive results from poppy-seed ingestion. However, the sensitivity for detecting true opiate use can be a concern,112 and most clinical laboratories continue to use the lower cutoff.53 Positive results for heroin abuse are caused by use of prescribed opiates, such as codeine and hydrocodone; however, ingestion of modest amounts of poppy seeds has been known to cause a positive result from urinalysis. Ingestion of poppy-seed cookies (containing about 1 teaspoon of poppy-seed filling available commercially in the United States for baking) produced positive results for opiates within 2 hours of ingestion among 5 patients.62 Codeine was also found in a concentration of 20 ng/mL in 2 samples 2 hours after ingestion. Urine samples analyzed after 24 hours were negative for opiates. Similar results were seen in another analysis in which consumption of poppy-seed bagels produced positive results for codeine and morphine up to 25 hours after ingestion.60 A single bagel was estimated to contain 1.5 mg of morphine and 0.1 mg of codeine. Similar results were observed in other analyses with slight variations ranging from 1 hour for earliest detection of morphine to 60 hours for the latest detection.20

  • I think I got my car at the right time… it has Android Auto and a few automated features that I really appreciate, like auto headlights, pushbutton start, and adaptive cruise control. I can control some functions via an app on my phone, like remote unlock and remote start, which has come in very handy on several occasions. But it still has physical controls for all the commonly used and critical functions. It doesn’t have a huge glass panel taking up most of the dashboard.

    The one and only feature that really truly annoys me sometimes is the reverse automatic braking. It uses sensors on the back of the car, and if I have my hitch-mount bike rack in place it freaks out. I can disable it, but only until the next time I start the car, and every time I have to hold down a software button on the touch screen for 3 seconds. While I’m trying to back up. There should really be a physical toggle button for that.
