I started work last week at a small (~10-15 employees) tech company in California as an intern. Since marijuana is legal here for both medicinal and recreational use, I've been considering pursuing medicinal marijuana to treat anxiety. I already obtained a doctor's recommendation, but I'm having second thoughts in the event that my company decides to drug test me. I haven't been tested yet, and I've already been working here just under a week.
I like to think I've made a good impression so far (I've done my best to go the extra mile and my boss has complimented me on the work I've done so far), so I don't think I give off the impression that I'm a slacker or stoner. While the workplace policy doesn't require drug testing, it does allow for random tests, and since my company does take on federal contracts, it seems possible.
My boss seems like a relaxed guy so I was considering sitting down with him one-on-one, and explaining that this was something I was considering after already having been to counseling, while emphasizing that I would never come to work under the influence or let it affect my performance, and that the job is my priority. Is this a bad idea? Could this reflect negatively on me? Is there a better way I can approach this?
They're a private company, they could simply decide that I "don't fit with the company's culture" or make up any excuse they want - but even if they don't fire me, this is just an internship but it may be somewhere I want to return to some day so I don't want to burn any bridges.
