<human>: Can you provide a brief rundown of the text in within 3 sentences?

(To start, I should point out I'm in the UK)

So in the past few months my S.O. has been smoking quite a lot of cannabis in my house. This doesn't bother me too much but she has also been spending a lot of time with someone who is a heavy cannabis user and also has ties with a fairly well known dealer locally (the dealer also deals in harder substances). She frequently has weed in the house (not enough to deal) and has quite a lot of drug paraphernalia.

I personally don't want anything to do with the stuff. I don't mind people who smoke it and I do believe the laws should be relaxed but since it's currently illegal, I wish to play by the rules.

What my concern is, is that if she get's caught in possession in my house (whether it be due to a random search or if the dealer get's caught and they follow the chain) then I could potentially get bitten in the ass for it.

I have tried speaking to her about it and I've voiced on numerous occasions that I'm not happy with her using cannabis in my house but she is insists that nothing bad will happen and calls me a hypocrite due to my stance on the substance.

I guess my queries are:

1) Should I worry?
2) Am I legally responsible about what happens in my house? (I own the property, it's not rented)
3) If she gets caught and prosecuted, could this effect me in any way?
4) Is there anything else I should watch out for in terms of drug laws?

Thank you all for your time
<bot>: S.O. smokes cannabis in my house and has ties with a dealer. Could I get shafted if she's caught?
