The neat thing about dipstick testing for illegal drugs is you can fool the sticks easily enough...a little salt, too much water, what have you.
These days, they use "GC/MS" drug testing. It means "gas chromatigraph/mass spectrometer." It is a computer-driven instrument that can screen for just about anything you want. You cannot fool the GC/MS because it knows what chemicals are in, say, THC, and it will detect those chemicals in the presence of adulterating agents.
URINE TESTIF YOU MEAN A NEGATIVE reading for drugs, the answer is NO. They check your urine for more than just drugs. They check the temperature of it, creatinine, and other chemicals to make sure that you haven't tried to dilute or otherwise mess with the sample. The only way to get a negative reading is to not use any drugs for at least 4 days before the test (5 weeks for marijuana). Some people try to drink tons of waterfor 2 days before the test, to try and "flush" out their system. HOWEVER, if you do that, they can tell that the urine is diluted, and that's an INSTANT FAIL. Stay off all drugs (unless they are legally prescribed by a doctor), and you will pass. They check for EVERYTHING: cocaine, marijuana, narcotic pain pills, speed, heroin, tranquilizers, EVERYTHING. Nowadays, it's very difficult to fool a urine test. Good Luck! <<Sample format of Table of Specification

periodic table
You look the number up in a table.Example:Find the logarithm of 511From a table I see that numbers are only listed from 1.00 to 9.99I look up 5.11 and know that I have to multiply that by 100 or 102 to get my original value, which is equivalent to adding 2 to the table value.The table gives me 0.7084209 for the logarithm for 5.11The logarithm of 511 is thus 2.7084209For numbers less than 1 the logarithm will be negative!Negative numbers do have logarithms!

ok wait!
Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.

Most negative ions are found in elements on the far right side of the periodic table. But, if you have a decent table, you can find the possible ionic charges for each element. Look for the negative numbers.
