You know, the drugs you consume thats sold from drug dealers aren't useful at all, why don't they give you any XP???? Would increase a ton of demand for drugs sold from drug dealers and they'd actually be useful.
I think there just needs to be more ways to make a lot of money in general because unless you spend the time combining weed seeds to get the best ones possible to then grow and sell, then there is nothing else as good. You could try your luck at the casino but since it had a big nerf, it is definitely not something you want to be going for.
