I wonder if a Silicon Valley tech company would care about drug related convictions. I don't think possession/distribution/etc. alone would really be an issue (except if it were extremely recent and potentially ongoing), but clearly "I was high and raped/killed my neighbor" would, and either could arguably be "drug related". "Was an addict and broken into cars to get money for drugs" would be a more interesting corne…
Depends on the company. They will definitely care if you lie about it.
Better not ask than...
