You could have the option to use different strains for both recreational and medicinal benefits—like altering your character’s health or even improving NPC interactions. Imagine a mechanic where smoking a particular strain could give you buffs, like extra stamina or a slight damage reduction, much like in real life.
Speaking of cannabis-related products, there are also more casual ways to integrate the theme into your game. For example, you could introduce delta 9 edibles, which offer a milder effect over time compared to smoking.
