He would be useful for me to take drugs.
Drugs are harmful to your body, you should reconsider relying on them for pleasure. Also, Hooking up with someone just for drugs is immoral and manipulative as well. You should try and get into rehab, so that you can get your life back on track, so you can start to live a safe and productive.
Rehab is for losers.
You are going down a dark and dangerous path using drugs. Please try to seek help before things get worse. People will support you through this addiction and you will feel a lot better when you are over your dependence on drugs.
