Did I ruin my chances to be a LEO?

[Skin1991]

So here it is, I have been doing alot of tactical training and been thinking of getting my executive protection certificate but recently have thought about going to the police academy and trying to get a job as some sort of LEO. My question is when I was in highschool my senior year, I made a stupid mistake and got a medical marijuana card, it was stupid because I smoked pot maybe 4 times, I honestly got it just to have because I was 18 and was with the wrong crowd, and realized I didn't even like smoking the crap and regretted even getting it. I obviously no longer hang out with those kinds of people and havnt smoked anything in about 3 years. So did that stupid choice ruin my opportunity?
