I looked this up online, and now I'm left even more confused. Below is what I found. If people are modding Fallout New Vegas, It was for the worst.
"Party-Time Mint-als (or PTMs) are a special and highly addictive variety of Mint-als. They are used to dramatically increase mental function and charisma while boasting some rather unusual bonuses. Pinkie Pie used PTMs to drastically increase the power of her "Pinkie Sense" during the war, but her addiction led to arguments with the other Ministry Mares. Littlepip learned the evils of PTMs the hard way after being introduced to them by Calamity, who uses them as a cure for hangovers." Pinkie Pie (full name Pinkamena Diane Pie), introduced in Chapter 4, was a pre-war earth pony mare and a minor character in Fallout Equestria. She was a member of the Ministry of Morale, serving as its director. Prior to the war, she was one of the original six wielders of the Elements of Harmony, representing the element of Laughter.
