I failed a pre employment drug screening

After a completely clean driving/safety/drug record of 35 years, I failed a pre employment drug screening. (I smoked pot at my going away party.) I am having a hard time getting anyone to get past that, even when applying for warehouse/yard jobs.

I need the work to pay for the SAP thing I have to complete before getting my CDL endorsement back. My worry is that no one will hire me at either point.

Does anyone know what I have to look forward to?

Thanks.
