I'm really high on some good marijuana and alcohol right now.
Why would you want to mix both of those?
I just want to have fun. I want to be lightly high and drunk for a long time now.
It's not good to spend too much time high and drunk. Your every day life and work will suffer from it and you could develop an unhealthy habit.
I just want to have fun for a week. Everyone will be fine after that.
I get that you want to have fun, but mixing the both of those can really impair your judgment. Hopefully you are in a safe space and will remain there until you are sober again.
