So as usual I asked my SO how her day at college was going around lunch time and I she replied that she was too unmotivated to go in, this happens sometimes yeah. So I asked what she was upto and she replied she was going to be having a smoke to which I replied "what are you smoking", she informed me that she wasn't home yet. As you might I simply asked "so where you been to this morning? anywhere good?", she flat out refused to tell me and asked me to drop it. I asked her again and she said she hasn't been anywhere and to just relax. 

I understand it might have been something personal but that can normally be summed up by saying a doctors appointment or such. This is the first time it's been sprung on me and I'm quite unsure as to why she would refuse to tell me. Should I be somewhat worried as to where she's been? I'm left wondering mainly whether it's drug related as it wouldn't be too much of a stretch.

Am I right in perusing the truth?

my SO refuses to tell me where she has been for the last week. I'm wondering if it's drug related and are now wondering where she's been.
