Here is YayaSimblr's Stoner Essentials for TS2! You get cigarillos (*cough*), a Bic lighter set, and some blunt spray. All can be found in Deco - Misc for $100, except for the blunt spray which is $160, same section, and requires FreeTime.
Do you like what I do? Then I'd love if you donated. Any amount helps!
