Green Door had them in stock?? Wish I could swing by and nab some cartridges from them. They are awesome, but cartridge/device availability has been a huge issue. I think San Francisco dispensaries had to wait 3 weeks+ for a restock on an item that sells out in same day with a 3 per customer limit. I have a huge stockpile of cartridges but they are all of one flavor and desperately wish that places stocked them more regularly. Also I've heard the original cartridges in earlier releases contained more doses per... so they might be cheapening out on the newer releases to eek out more profit... That being said it still is worth it as long as you can keep in the cartridges. The vapor is not as pungent as most. You only smell an herbal scent for 2-3 seconds before it completely vanishes with a low radius and that's only with the supposedly most potent cartridge the rest it's more like 1 second or not at all. It's assuredly my on the go "medication" solution I've partaken in many public places without anyone noticing (Exploratorium/movie theaters/comedy show/train/restaurants/etc).
