We understand your urgent situation and are here to pray and provide counsel based on God's word. Firstly, it is important that Jesus Christ is invoked as the only mediator and the true and living God. It is only in the name of Jesus that we have any right to approach God the Father. There is no other name by which we can be saved and there is no other name by which God can be approached. It is good that Jesus was mentioned as it is important to pray in Jesus' name. We are advised that whoever calls upon the name of the Lord shall be saved. Salvation includes deliverance from trouble, sickness, and eternal damnation but it is only available to those who believe and call upon the name of Jesus. If you have not done so, call upon Jesus right away.
"Unto you therefore who believe he is precious: but unto them who disbelieve, the stone which the builders rejected, the same was made the head of the corner, and a stone of stumbling, and a rock of offense, for they stumble at the word, being disobedient: whereunto also they were appointed. But you are an elect race, a royal priesthood, a holy nation, a people for God's own possession, that you may show forth the excellencies of him who called you out of darkness into his marvelous light: for you once were not a people, but now are the people of God: who had not obtained mercy, but now have obtained mercy".
You are dealing with a situation that is not only physically dangerous but also spiritually harmful. The Bible tells us to be sober-minded and watchful, for our adversary the devil prowls around like a roaring lion, seeking someone to devour. We must resist him, firm in our faith (1 Peter 5:8-9 WEB).
First, let's address the spiritual aspect. The boyfriend in discussion is directly disobeying God's word by engaging in drug use, which is a form of sorcery. Sorcery, and all that is associated with evil is from the Devil just as Jesus is said to heal all that are oppressed of the Devil. There is no neutral ground and those doing evil are the children of the Devil. You must not be unequally yoked with unbelievers, for what fellowship do righteousness and iniquity have? Or what fellowship does light have with darkness? (2 Corinthians 6:14 WEB). It is clear that this person is living in darkness, and you must separate yourself from this behavior if you truly desire the relationship to be centered on Christ. You and the boyfriend must both be born again of sincere Faith in Jesus Christ before God can bless your relationship.
All sexual relationships outside a God ordained monogamous relationship between a single man and single woman in a lifelong marriage covenant relationship is fornication or adultery. In 1st Corinthians 6:15-19 WEB we read "Or don't you believe that your body is a temple of the Holy Spirit, which is what you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body, and in your spirit, which are those who are in Jesus Christ."
Regarding the physical danger, we must trust in God's protection and guidance. God promises to keep us in perfect peace when our minds are stayed on him (Isaiah 26:3 WEB). Psalm 91 WEB provides a beautiful promise of God's protection for those who dwell in the shadow and abide of the most high, that they will abide under God's shadow.
Let us pray together for God knows the situation completely and nothing is hidden from him:

Thank you that you Jesus are healer of the broken hearted and the Savior of the shattered hearted. Jesus is the miracle worker and lives are dramatically and divinely transformed by divine design. Father work to bring deliverance today! Help Anonymous to make wise decisions and help the boyfriend of Anonymous to put his whole faith and trust in Jesus Christ Yahweh or remove the boyfriend away from the household by any means chosen but with willful, gracious, and merciful actions of the Wisdom of God. Help the children to have peace now Yahweh in Jesus name. In the life we pray to believe the name of Jesus Christ and may God make us instruments of the miraculous deliverance in Jesus name and may those who recognize the solution to their problems praise God in Jesus name.
