That is, we’ve been working in the S domain with transfer functions. We’re going to stick with frequency methods with transfer functions for the next few videos, but instead of working in the continuous S domain, we’re going to switch over and start to understand how to design control systems in the discrete or Z domain.

We Tested Drinks That Say They'll Help You Pass a Drug Test. When it comes to balancing a professional life with even a casual weed habit, American stoners have a delicate line to walk.
Despite being recreationally legal in nine states and medicinally legal in 29, the federal ban on marijuana consumption means employers across the country have the right to refuse or terminate the employment of anyone who fails a drug test for THC. While Jeff Sessions seems to believe otherwise, countless studies have shown marijuana to be significantly less dangerous than other Schedule I drugs like heroin and cocaine and much safer than legal substances like alcohol and tobacco. To add insult to injury, when it comes to pre- or post-employment drug testing—which most often takes the form of a urine test—marijuana is the substance that takes the longest to get out of your system. According to a poll released by the Society for Human Resource Management, about 57 percent of American companies subject employees to drug tests. That’s down significantly from 81 percent in 1996, possibly because employers are finding it increasingly difficult to find quality candidates who are able to pass. Luckily for them, and those of us who enjoy the occasional after-work blunt or who use marijuana to treat otherwise unmanageable chronic illnesses, there’s an entire industry devoted to beating the dreaded piss test. With enough advanced notice, there might be several ways you could go—quitting outright, subbing your dirty pee with a straight edge friend's. But if your boss springs the news on you with only hours to spare, you’ve got pretty much one viable option: the detox drink. There are several of these on the market, “cleansing supplements” that, at a glance, seem to be nothing more than herbal energy drinks. On the back of each bottle, the language used is deliberately vague. “Drink the entire bottle 60 to 90 minutes before your desired time .” “Frequent urination indicates that you are experiencing optimal cleansing .” These drinks can be expensive—up to $60 a pop—but that’s a small price to pay when your job may be on the line. They all offer the same thing: a same-day, temporary fix for your THC-tainted piss, so long as you use ‘em exactly as directed. This is a question even the most diligent Googler is wont to find. As it stands, all the available information on these detox drinks seems to be either an obvious paid promotion for one brand or another, or come from anons with usernames like Stoner4Lyfe420 on eight-year old marijuana message board threads. As such, we decided to put three brands to the test: Our test was simple. We ordered a 10-pack of THC pee tests from Amazon for $7.99, and recruited a regular recreational weed smoker—a 28-year-old woman we’ll call “Jolene”—to test out these drinks over the course of a week without altering her normal weed habits. She’d try out one drink every two days, and take a control test before starting each one to make sure she was still testing positive before drinking them. Then she’d follow the directions on each bottle and see whether she could piss herself clean. Jolene’s pre-drink drug test came out very positive for THC. In the photo above you'll see Jolene's first pre-drink test.
The C on the test stands for Control The line next to it appears whether the test is negative or positive. As you can see above, Jolene was not able to produce a T line because she is high af. The drug tests we purchased are pretty standard pee tests. Basically you wee into a cup, take the cap off the drug test, then submerge the little rectangular piece at the end for about 10 seconds. The test we bought for the purposes of this experiment are used specifically to detect THC and nothing else. For context, Jolene’s marijuana consumption is probably slightly, but not much, below average for stoners. She smokes a bowl most days after work, and blazes up two to three times a day on the weekends.
Occasionally she’ll have an edible or do a dab, but says she usually sticks to traditional smoking methods—bowls, bongs, and joints. Most of these drinks caution “heavy” users to double their dosage, or go with a more concentrated version, so if you smoke more or less than Jolene, you’re likely to have different results.
