Have just come back to this - had a very busy day.
This boyfriend - you haven't met him, you have heard bad things about him: drugs, police etc...
How old is he?
2 things strike me:
If he is supplying her with drugs, he is committing a criminal offence.(sorry - but I think he probably is)
If he is having sex with her (she is 15)he is committing a criminal offence.
He doesn't want to meet you/come to your house - I don't think he is a "boyfriend" in the conventional sense of the word.
In your situation I would try to find out a bit more about him. Ask your local policeman??
IME aggressive confrontation and destruction of property do not work. You have probably gone beyond that, and you don't want to drive her into the arms of this man/boy and his friends/associates. Keeping your relationship/communication going with your dd is vital - she needs to know you are not the enemy.
Temporary confiscation together with communication, clear expectations and consistancy do work. Your husband has chosen to opt out of his role and responsibility as a parent. Somebody needs to be in control in this relationship - if you don't step up and do it, the boyfriend will control your dd. She is too young to take control herself.
Removing money, phone and transport will help to keep her safe until you work out a longterm strategy.
Every conversation I had with Ds1 even during the darkest times, contained the words "I love you, and I want the best for you". I tell all my children on a daily basis that I love them - it is really important.
You need to talk to someone - either via your GP, or talk to FRANK - (drugs advice) - you can google if you don't know about this.
Is there any way you could take your children away for a holiday, or send dd to stay with a trusted relative for a while?
I even considered boarding school (state - couldn't afford private) to get ds away from the company he was in.
I think your dd is at risk, and while education about safe sex etc is important, I have a bad feeling about the lying about her whereabouts, the source of the money for "tobacco", the boyfriend not wanting to meet you, her erratic/moody behaviour. It all sounds depressingly familiar.
Signs of cannabis use are easy to find out - google or ask FRANK.
Sounds like she isn't using it at home though.
Legally she is a child - she needs you to protect her.
