It really depends on my mood and the specifics of the public situation. I used to really prefer public, I would regularly go to school on a variety of drugs and got a kick out of it. There was something about doing normal, boring stuff while high as fuck that I found appealing. Luckily I never got caught (the risk of which was probably half the fun). Nowadays, I still like to go to the movies, restaurants, or walk around town while under the influence, but I also enjoy using in my own home. Usually it works out to me going out with friends, getting high, drunk, doing speed or rolling, and then coming home, smoking more, maybe taking a xanax, watching a movie with my girlfriend and falling asleep.
