How much do pre-rolled joints cost?

I don’t consider myself to be frugal, I just use common sense and am not afraid of a little work.

Take going out to eat as the perfect example.

It costs as much for a nice dinner out as it does for a whole week’s worth of groceries. I know so many people who eat out several times a week, and then complain about having no money. No kidding, you spent it all buying food that you could have made yourself. Some people would rather go broke than to actually cook a meal, I suppose. A sillier example involved my friend Rolf and the amount of money he spends on pre-rolled cannabis joints. Rolf could buy a fat sack of cannabis and a pack of rolling papers and roll all the joints he wants. Instead he pays five times more than he should to get the pre-rolled cannabis joints, just to save him the extra effort. He tells me that the cannabis in these joints has been infused, but he never says what they have been infused with. He may not know himself, he is just lazy and doesn’t want to twist up all that cannabis himself. I should start buying cannabis for him and pre-rolling his joints, for a few bucks. It would save him some money, and make me a little! Personally I rarely smoke joints, because I prefer the crisp, clean taste of cannabis smoke filtered through water. I have a very nice three chambered water bong I use for my finest cannabis, and a glass pipe for the other stuff.
