AITA?

Been dating guy for about 6 weeks, showed up to his place to give company as he mentioned about having a really bad day and when I walked in I smelled a hint of weed so I asked what it was and he told me that he has medical grade marijuana prescribed by his doctor to help ease his anxiety as he said he used to be on a low dosage prescription but over time didn’t like how taking pills made him feel dependent and the side effects. Wanted something more natural path, so his doctor recommended cannabis as an alternative, he said he just took an inhale about 40 minutes before I showed up. He also volunteered he doesn’t smoke to get high or gets high, but to help ease the relief of built up stress. I was taken a back as I didn’t know this before, and he said he completely understood and apologized for how I felt surprised and mentioned that it’s not something he goes about telling people and does in the privacy of his own home. I asked when the last time he smoked and he said because he doesn’t depend on it nor wants to depend on it, it was about 4-5 weeks prior. I was completely turned off and disgusted from him using marijuana and feel I’ve been lied to and betrayed, so much so I sat several cushions away from him on the couch, wouldn’t look at him when he was talking to me, refused to hold his hand when he reached out and didn’t kiss him goodbye but instead just gave a hug and walked off. While I was walking to my car he asked if everything is okay, and I didn’t even bother to turn around and just said yeah and kept walking. I could tell he was uncomfortable and confused, good!! I didn’t bother to reach out until the next day just saying how him using weed in any form of capacity to me is HUGE DEAL BREAKER and to have a good life. He responded saying how he understands how I can feel taken back and said that if it bothers me he would completely stop no problem and just ask his doctor for another source of help if that made me feel more comfortable, but said that I am being a bit of a hypocrite because me drinking a bottle of wine for myself every other night concerns him of me being an alcoholic? wtf????
