A few weeks ago I took 1mg of xanax (half a bar) two nights in a row, and both nights I smoked weed about 6 hours after taking the xanax. Both times instead of feeling a euphoric high, I began feeling dizzy, and couldn't really focus doing anything except going into bed. I figured that I was maybe just really tired those nights and the weed made me even more tired, but last night I again smoked weed 6+ hours after taking Xanax (this time 2mg, and as a note I am not prescribed xanax, it's purely recreational), and I got the exact same feeling. Is this common? I have never heard of this happening to anyone, but every time I have smoked weed after taking xanax, I feel very dizzy and can only focus on going to bed.
