Need help on deciding whether to apply or not

Hi all,

Hope you all are doing well! It’s always been a dream of mine to be guard but fear my decisions in the past will not let that happen.

I had a minor cannabis offence in college and everything was thrown out and that but I stupidly didn’t learn from that and continued smoking occasionally up until a month ago when I decided I need real change in my life.

I was recommended to many people including current guards to apply as they think it’ll be a great fit for me (they have little knowledge of my smoking) and was told to apply at the next intake.

I’m just seriously worried that if I do apply my past may come back to haunt me or more than likely the fact that I was smoking so recently will definitely kill my chances.

Any advice for me (with as little judgement as possible please)
