  • Mixing weed and snow: Visual Distrotions?
    Not sure if this is something others experience, or if this is all just part of my HPPD lol. Its not bothering me but almost looks fluid like molly. Really curious to see if this is a thing becuase its also new to me. Not really tweaking too hard. Using this fucking awesome type timer called squibler.io highly reccomended. Who would've thought the motherfucker asking about mixing coke and weed would get this... Source: over 4 years ago
