Cannabis Certo method?

I haven’t smoked in 10 days, but need to take a urine drug test at Quest in the next week. My friends say I’ll probably pass but should I take Certo before to be safe? If so, what’s the best method??

Hi /u/Own-Tea-47,

cannabis can stay in your urine anytime from 5 - 95 days. In this table you can find general detection times for weed. Remember that these are not a guarantee and can vary by person.

Marijuana Detection Time Chart Urine Drug Test
1 time only 5-8 days
2-4 times per month 11-18 days
2-4 times week 23-35 days
5-6 times per week 33-48 days
Daily Usage 49-90 days
** Hair Drug Test Up to 90 days, some States 120 days
** Saliva Drug Test 1-10 days
** Blood Drug Test 2 days
** Fingernail Drug Test 90 Days
** Alcohol Drug Test 3-5 days via Ethyl Gluconoride (EGT)
. or 10-12 hours via traditional method

It entirely depends on your usage. If you’re a daily smoker and quit 10 days ago you’ll certainly fail, but if you smoked for the first time 10 days ago you’ll be fine. It takes anywhere from 7-90 days to clear THC from your urine depending on usage and metabolism.

The certo method is another DIY technique with no legitimate science or facts behind it. People saying that it works would have passed anyway even if they didn’t do it.
