Do they drug test for a team lead promotion?

So I thought I had until September until I was eligible for a promotion, but it turns out I am being sought out for multiple positions and I could be promoted very soon. I really want this, and I feel really honored thattheyre essentially letting me pick where I’d like to go. the issue is, since I thought I had months to prepare, I’ve smoked some weed recently. Do I gotta invest in a detox kit ASAP?
