Heck no i never herd of such!!
Doxycycline is an antibiotic, why would it? No.
No, it does not. That is a stoner myth and is completely untrue. That is not how the body works and THC is stored in your fat cells and can take up to a month to clear out if you are a habitual smoker, nothing you can take will do anything except attempt to mask the THC, but if the sample goes to a lab, they will find the contaminant and the THC as well.
Water, Vinegar, Niacin, Pickle Juice. You can get water pills or niacin pills and those will flush your system out. I've even heard of friends drinking a cap full of bleach with a glass of water to clean out there system. I'm not sure if it works but they have all believed it has.
No, it can actually make you fail
No, it will help the body to flush any fluids.
Yes it will with THC if used exactly how it says on directions. You must be free of THC for 48 hours prior to drinking Speed Detox.
Bad news, it doesn't work. THC has the property of being fat soluble and is stored in the adipose tissue, which is why it can still be detected as long as a month after use.Nothing taken internally will have access to this body compartment. Eventually the THC concentration level in the fat will lessen as fat is normally used up and replaced.
You cannot hide THC. THC clings to your fat cells and as your fat cells burn off the THC disappears. You can speed up the process through exercise and proper diet. Also I am not 100% about this, but you can buy body cleansing pills that flush your system, but since THC clings to fat cells I'm not sure how well it would work.
Nothing can get it out, only cover it up temporarily.
To eliminate THC from your system, you need to stop using it completely and allow your body time to naturally metabolize and excrete the remaining THC. You can also try drinking plenty of water, exercising, and eating a healthy diet to speed up the process. Additionally, detox products or drinks may help flush out THC more quickly, but their effectiveness can vary.
No. Percocet will cause you to fail a drug test for Opium (Heroin). if you smoked marijuana recently you will also fail for THC metabolites.
If you need to take a drug test, but you know you have THC in your system, the best thing to do is, and this is gross, drink vinegar. I have heard that this will flush the THC out of your system, but I'm not positive about that. Another thing, drink A LOT of water before taking the drug test. Sometimes if you drink enough water your pee will be diluted and nothing will show up on the drug screening.
