Can I Pass Security Clearance with Marijuana Arrest?

[TheNE]

I have a general security clearance question. Could I still pass for a Q or L security clearance, if I have a single arrest incident for marijuana? I was NOT convicted of any drug-related offense (hired a good lawyer), but instead was convicted of a noise violation. I have passed a clearance to operate a research/educational reactor before this, but haven't had Any checks on me since.

Thank you.
