I wanted to try concentrates for some time now but they were not available here. Since a while I can buy them in a few coffee shops in Amsterdam but never tried them. They are stupid expensive and can go anywhere between 75$ and 130$ for a gram so my question, are they still worth it? Can I buy a gram and load it in a pen vaporizer and be good for lets say a month? How many puffs does a gram yield and how many do I need to feel medicated. Our preferred way at this moment is to load about 0.3 to 0.4 gram of flowers in the pax, put it on red and both me and my wife go at it untill there is hardly any vapor left. This is what we want to achieve with the concentrates but I'm afraid that it's going to be so much more expensive this way.
