FAMAS | Bad Trip was added to CS:GO on September 3, 2018, as part of the FACEIT 2018 London Major update. It is obtained from the 2018 Inferno Collection, which was released alongside the London 2018 Major tournament content.

This skin features a psychedelic, graffiti-inspired design with vibrant, swirling neon colors like green, purple, and yellow covering most of the weapon, creating a chaotic and eye-catching effect. The pattern is accented by playful doodles and abstract shapes, embodying the 'bad trip' theme.

Bad Trip stands out as a unique and colorful option for the FAMAS, attracting players who favor bold and unconventional skins. While not among the most expensive FAMAS skins, it enjoys steady demand due to its distinctiveness and association with the Inferno Collection.
