Weed isn't legal where I live however its easy enough to access. A thing i really dislike about weed is in my (and most of my friends) experience its possible to just accidentally get to high and have a panic attack or freak out.
While this is possible with drinking, I find its much more difficult especially when drinking beer as I do. It has to be a much more conscious decision for me to get wasted drunk than for me to accidentally get so stoned I hide in my room.
