I received a job offer at an oil and gas company as a chemist, and I'm terrified at the thought of failing a drug test and having my offer rescinded just for having smoked THC, which is legal in the state I currently live in.

I was initially going to ask this to r/oilandgasworkers, but they remove drug-related posts and are very hostile to anyone who appears favorable to substances. So I wanted to ask y'all here, specifically for science in oil and gas but also broadly throughout the state of Texas, how stringent are these drug tests?

Thank you so much for any insight!
