AITAH for not giving a long time friend a break 🤷🏿‍♂️

I've been friends with this cat for over 10 yrs, a few years back we lost contact after I left the place we were employed. Since then he's been homeless, and unemployed. I let him spend the night thinking I might let him rent my spare bedroom. Well let's just say I caught him lying to me twice, and while we were playing COD he excused himself and evidently went and smoked crack or meth because he was tweaking the rest of the night. I'm a single medical professional. Weed is one thing but those stimulants I can't have in my life. I confronted him and he blamed his behavior on some concentrated resin he bought at the dispensary. He says he won't buy it again. I call B's cause he was GEEKED last night I'm not a fool. Should I give him the benefit of the doubt or cut ties immediately 🤦🏿‍♂️🤔🙏🏿
