Ever heard weed lovers talk about using Sure Jell, aka Certo Pectin, to pass a marijuana drug test? It’s a real thing, and after many trials, a lot of users believe that, if used correctly, Certo Pectin can help a person beat a marijuana drug test. Learn what it is, the way it works, and how it can best be used to pass a urine or blood test.

What is Sure Jell?

Sure Jell and Certo are popular brands of fruit pectin that people use to detox in preparation for drug tests. Fruit pectin is a compound commonly found in jams and jellies, and both the Sure Jell and Certo brands are manufactured by the same company, called Sure Jell.

Note that abstaining from marijuana is the only sure way to pass a drug test. Do not try to cheat on the test with Sure Jell or any other product.

How Does The Sure Jell Method Work?

The Sure Jell method works by affecting the solubility of THC metabolites. THC metabolites are stored in the body’s fat, which becomes water-soluble when bound to bile. Fruit pectin binds to bile, preventing the water-solubility of the THC metabolites. As a result, the THC metabolites are forced out of the body via defecation instead of urination.

Many marijuana users have a misconception about the way that the Sure Jell method works. They think that pectin can coat the stomach for a certain amount of time, which blocks THC and other toxins from getting mixing into the urine. The reality is that there is not enough data to support this idea.
Experts who administer the drugs tests look for marijuana metabolites in a person’s urine. THC is the first one that gets released from the body when defecate. What’s left in the urine is what has been absorbed from intestines.
The main metabolites of THC then enter the bloodstream. These metabolites are soluble in fat, and the majority of the THC that was stored is present inside fat cells that come from the food eaten. The body produces bile to mix with that ingested fat and then it gets dissolved in water — the pectin mixes in the intestines. The method is believed to be effective because the THC is temporarily forced out of the body when poop. This gives enough time to take the test and pass.
Aside from that, the process requires to chug down plenty of water that will dilute urine and give a better chance of passing a drug test. It’s also recommended to stop using cannabis at least two weeks before the test to ensure a negative test. However, this method won’t give a 100% guarantee of passing the test successfully. Some users reported that the traces of marijuana were still identified in the body after following all the instructions of this method.

    Worked for me! Sept 2019 Just make sure you really drink the whole gallon of water after drinking the Certo drink and the B12 combo pills helped with color.
    • brie
      did you stop smoking before hand or just drank the drink and then took the test?
    • ShahirA

    • Griffin Richardson
      Does the sur jell block alcohol?
  • Jason
    It actually coats the kidneys and doesnt allow any metabolites to pass through to the urine. It does in fact work if timed correctly its very effective to pass a urine test.
    • Josie
      Can u tell me gow to do it step by step?
    • Jen
      That is not correct. It works by absorbing the THC and forcing it out in fecal matter. It DOES NOT cost anything.
  • Judy
    You only have to mix it with 64 oz. Of water. Pee once, then drink something with yellow coloring on way to test. I’ve never had to use it, but I had 3 sons a nephew and scores of friends who has been successful in every test.
    • krystal sly
      Cool thank u
    • Shanaya

    First time I tried it I drank an entire packet mixed with gatorade then filled it back up and drank another bottle of water. When I got home I pissed and I was still positive for THC. Today I didn’t have any other options and I really needed to piss clean I smoked about a week ago so I know there is THC in my system still. I drank 2 Tablespoons of apple cider vinegar and 2 tablespoons of lemon juice mixed with water. (Horrible taste btw) I then waited about 5 hours and drank the CERTRO straight from the packet and almost threw up its syrupy so it’s kinda hard to get down but you gotta push threw. I then drank 7 plastic bottles of water in about 2 hours. Let’s just say I was pissing completely clear my pee was hardly warm while coming out. (I’m still peeing every 5 minutes) my mom really wanted me to pass so she told me to let alittle of the pee out first because that is most likely the strongest “dirty pee”. Then the most intense 5 minutes of my life begins this is a 12 panel drug test and is very expensive (long backstory why we have them) and when she peels it back all drugs came back negative in my system so I really recommend doing this it’ll suck because it taste really bad but if you need to pass the day of I really recommend this.

    does the SURE JELL certo still work if i’m not taking a piss test?
    • Adrienne Hein
      No because it is only affecting the contents in your urine.
  • Erik
    Will it work same day?
  • KB
    IT WORKS! I smoked and ended up having to take a drug test the next morning. I drank the first Certo mix along with A lot of water that night and drank the second mix with a little less water the day of. The b12 didn’t give my pee any color until waaaaay later so that was concerning. My sample did, however, get flagged and sent to the lab but I still passed, this method SAVED MY JOB. I highly recommend it friends

    Certo works like a charm. I was using suboxon and crack up till 6 hours before I had to drop. One pack of certo in power aid. Drink then drink 2 more bottles of water behind it. Piss 3 times before you go and bam clean test. Ive done this several times and never had a neg. Result. I quit using Monday because I knew I had a drug screen for job friday. This morning I gave myself a test and I was still positive. Couldn’t believe it. Went and got one pack of certo and took 2 b12 pills for yellow color 2 hours later took another test and bam instant clean results. This s**t is a life saver and all for under 10 bucks
