It depends on the machine. Different materials are penetrated differently by x-rays, and some machines are tuned to pick up on the level of resistance typically caused by Marijuana.
The latest x-ray technology uses backscatter technology. They not only capture the radiation that goes through an object, but what bounces back as well. Then a computer cleans up the image. So things like bricks of illegal drugs can by found inside of vehicles using x-ray trucks.
Yes, marijuana is legal for medical use in Delaware, but recreational use is still illegal. The state has decriminalized possession of small amounts of marijuana for personal use.
Yes, unless you hide it in a lead box, marijuana will show up on both the carry-on x-rays and your x-rays. The #1 thing someone gets caught with at airports is marijuana, especially small amounts. However, the TSA has removed the full-body x-rays from major airports, so carrying it on you would get through.
the chemical test that is done to detect blood in the feces in amounts too small to be seen.
I am very interested in this as I have Lyme Disease (LD) and have finally come to the conclusion that marijuana contributes to it/worsens it. LD also lowers serotonin (and important related proteins such as tryptophan) and thus it is important to get serotonin (and protein!) when you have LD. In terms of marijuana, a recent article from Wired science (can't hyperlink for some reason, just google marijuana and serotonin) suggests that small amounts of marijuana increase serotonin, and large amounts decrease it. Thus, if you have serotonin deficiencies (or are depressed or are taking SSRIs) it is best to avoid marijuana, but I suppose small amounts may help. You may want to experiment, but personally I'm avoiding until I'm better. Marijuana is fun, but look inside: do you really need it??
Firstly, why is this under the Marijuana category? Do you mean purifying water? You can purify it with small amounts of bleach.
A ring baggie can typically hold up to 1 gram of marijuana. These baggies are commonly used to sell small amounts of cannabis.
It's not been 'legalised' in The Netherlands. It has simply been 'decriminalised' for small amounts. 1972 was the year though.
There are several reasons why you may consistently set off airport metal detectors. Common reasons include having metal implants, wearing metal jewelry or accessories, or carrying metal items in your pockets or clothing. It is also possible that the sensitivity of the metal detectors at the airport is set high, making it more likely for them to detect even small amounts of metal on your person.
In Texas, marijuana is illegal for recreational use and possession of any amount can result in criminal charges. Medical use of marijuana is restricted to a low-THC cannabis oil for specific medical conditions. Possession of even small amounts of marijuana can lead to fines, imprisonment, and a criminal record in Texas.

THC is the sole component in marijuana that matters and when in the body it gets transformed slightly by the liver, then processed and ejected. It is these transformed metabolites which are tested for.
A biometer is a device which is used to detect the presence of life by detecting and measuring small amounts of evolved carbon dioxide.
