Smart Camera Tells Tobacco From Marijuana 167

An anonymous reader writes "A new smart camera technology not only takes a picture but also assays chemical composition, allowing photographers to tell whether that hand-rolled cigarette contains tobacco or marijuana. Designed to speed industrial inspection systems — such as detecting whether food is spoiled — the new smart camera includes spectral filters that make images of corn fields appear differently from hemp. Spectral cameras have been available for decades, but this microchip version should be cheap enough for almost any application."

    I can see city police departments calling in orders for this right away. Just think of all the tickets and arrests they'll get out of one of these things!

    Who would want a tricorder that couldn't do spectral analysis? We're almost there!

    What are they talking about? The article says absolutely nothing about differentiating hand-rolled cigarettes, nothing about tobacco, and nothing about marijuana.

    Such as for example, spectral camouflage. Any method that depends on identifying spectra of compounds in a complex mixture depends on spectral deconvolution. Spectral deconvolution is easy to fool, but adding a compound that provides a "difference spectrum" , compensating for the differences in tobacco versus marijuana smoke.

    Here's a fix for that?

    Seed balls. [wikipedia.org] Just start walking around the neighborhood with a bag of these, tossing them into gardens, planters and median strips. Be especially sure to put them in the large planters you find in front of banks and other public buildings. Make sure you wear jeans, boots, hard hat and orange vest, so you look like a worker.

    Do this all over the place. Everywhere. Towns, cities, villages, technical parks; anywhere there is a planter or bare soil. Do it at night, and you can see entire media strips along the highway. Imagine 20 miles of flowers!

    If you really wanna cause trouble, make a modified fusen bakudan! [wikipedia.org] Take a 2-liter bottle and tie it to a weather balloon. Put a timing switch on top of the bottle. Run a string from the switch, through the bottle, to a stopper. Fill the bottle with seeds. Set the timer for 30 minutes, then release at night. When the trigger releases, the seeds will fall out and scatter over a wide area. If you make adjustments to the mouth of the bottle, it can be made to release them over a longer period, decreasing concentration but increasing dispersal.

    If you saturate the product all over the place, everyone will now have plausible deniability.

    Yeah, my dog ate my stash, man.

    Back in the days when I was still smoking weed, I was rolling a joint and noticed my dog was looking at me in an investigative way. So I took a small bud of weed and let her smell it. She sniffed, and then she shook her snout against my hand making me drop it. Immediately she took it, and ran away a couple of metres. I tried to get it back, but she turned her body keeping me away from it while she ate it. During the rest of the evening, she kept lying in the sofa, upside down, paws up in the air. Eventually she got up and ate her bowl completely empty, then got back into the sofa. It's the funniest thing I ever saw her do. I don't know if it's normal or not. Do dogs like weed? Mine did for sure.
