I could not swear to it but I spent some time in a court appointed out patient rehab where we had random drug screening with the color system and I had a friend in the program with me who I witnessed smoking marijuana many times who used niacin and as much water as he could gulp down in a few hours in combination with a multi vitamin and he passed his test in as little as 24 hours. I seen him pass a few test like that but this will not work if you have been smoking heavily I also seen him fail a test with the same method in the drug test passing business reframing from using is the only shure thing
I'm taking niacin and it will work because I am an occasional smoker.
In my opinion, the use of weed for health is a good solution and I treat stress in this way from time to time. Recently I was able to find a site https://westcoastsupply.cc/product/pink-kush-shatter/ with an interesting product for stress management. I think it will be a more pleasant way to treat stress. Of course, when conducting any tests at work, weed and weed derivatives should not be used.
