Straight talk, brother to brother.
No product can promise you a pass, and the only certain way is to not use. Tampering with a drug test can be illegal and is usually treated as a refusal. We never help anyone beat DOT, federal, safety-sensitive, or court-ordered tests. If substance use is getting on top of you, call the free, confidential SAMHSA National Helpline on 1-800-662-4357 (24/7, English and Spanish), or call or text 988 in a crisis. Source: samhsa.gov.
