In recreational states, prices can be all over the place, as can quality. I've had experiences in Vegas where I tried to use shake I got out of a cheap $10 preroll from a dispensary and vaporize it only to get zero vapor - I literally thought I had broke my vaporizer until I tried some high quality flower and got vapor.

Turns out the dispensary was making concentrate from dry flower, and then using the leftover shake (after extraction) to sell as pre-rolls, despite having essentially no THC left to vape. That should be illegal.

Anyway back to your question - different strains will produce different amounts of vapor depending on your device, temperature used, and quality of the herb. Low grade herb will produce minimal vapor and you'll need to cook a lot of it to get where you want to go. High grade herb will produce a ton of vapor at your preferred temp for that strain (Sativas cook best at lower temps, Indicas cook need higher temps, hybrids can be fun to customize your experience based on the temp used for extraction - different temps release different medical benefits from the flower).

What kind of vaporizer did you get? Some vaporizers are more "flexible" with load sizes - while others require a fully filled oven for optimal conduction of temperature and extraction.

I know an older gentleman who rips 0.015g of high grade herb twice a day through a massive desktop plugin vaporizer to get him where he wants to go. He may pay top $$ for that herb, but one single gram also lasts him a whole MONTH of medicating. Not all dry herbal devices work the same or perform the same - some are MUCH more powerful than others.

Last year I myself went six months with half an ounce while partaking almost daily.
