They definitely work AND WELL !!!
They do workโฆ I need to be nicotine free for an upcoming surgery and found out 2 weeks before that they test and if Iโm positive they cancel my surgery so I was anxious and curious. I bought these and have been testing everyday for a week. Itโs also helped and kept me motivated going cold turkey off the vapes and occasional cigarette. Exactly 1 week it took for a negative result. I drank A LOT of tea and electrolytes to flush my liver and kidney (donโt know if it actually helped but thatโs where nicotine is processed to be removed from your body so I figured hydrate as much as possible).

They work
We suspected that my son was vaping. These tests proved it and he eventually confessed. Look no further. Just buy this test kit.

Waste of money
These gave 7 positive rests in a row, for a non smoker of 3l4 month. Waste of money.
