Honestly you not going to like my suggestion. But here it is. You should buy a few 30 packs and get really drunk with them all. This is saying that i smoke weed but I will also party with you guys doing what you would like. Drinking with them will most definetly them a "I really like you guys and want to party with you" sense. While they are drunk I'm sure you could have an inebriated heart to heart talk and maybe settle things. I'm sure they think your "just a stoner" so prove to them that you can treat them to a good time. This may or may not make them respect your right to smoke.
