I'm a heavy smoker also with dabbing my choice of usage. I am wondering what can I do to pass a dt that I must take in 4 days. I normally use the synthetic stuff. Certo work before but I was only using regular and dabs are way more potent. I've been drinking water and this weekend I plan to fast. I tried the store bought masking agents but it didn't work. Wished I stop earlier but I didn't and taking home kits still I show a postive.
