The UDS is industry standard for pre-employment drug testing. Never heard of a Pharma company requiring a hair test. Those tests are usually reserved for jobs in specific industries/fields where security and/or safety are high priorities - law enforcement, jobs requiring security clearances, transportation, etc. Stop hitting the vape 3 and/or smoking bowls 3 weeks prior to your Labcorp visit and your should be okay. Once on board, resume hitting the vape and smoking bowls.
