"Friends" only want to hang out when we have weed 😡

Both me and my bf use weed medicinally. We have a group of friends who we hang out with who also all smoke. But it seems like some of them only ever hit us up when we have weed. If we say we can't contribute much to a group smoke sesh, they'll just stop responding to us trying to make plans. They never hit us up if we don't have weed - the few times they have and asked if we wanna smoke and we told them we couldn't contribute, the same thing happened... they just stopped responding. Like okay, cool, guess we know what your priorities are ✌🏻🙄
