The common ingredients required for crafting a schedule 1 laxative mix, such as Cuke, Gasoline, Energy Drinks, and Mega Beans, are readily available for purchase at the Gas Marts located in Hyland Point (specifically, the Western or Southern Gas Marts are mentioned as sources for general ingredients).
Base drug components, like seeds (e.g., OG Kush, Coca Seeds) or precursor materials (e.g., Pseudo), are typically acquired from specific suppliers who players must unlock and build relationships as they progress through the Schedule 1 game. For players who prefer to bypass the standard acquisition methods, the Schedule 1 game does offer console commands or cheats that can be used to instantly obtain items, including mixing ingredients.
