quirkster, one solution to this is to not be around your friends until you have this under control. But another solution is to ask your friends not to smoke around you. I have had a friend and family member ask their friends and family not to drink around them because they were trying to beat their alcohol addiction. I was HAPPY to not indulge while in their presence if it helped them. What are friends and family for? Maybe you are scared to ask your friends for their help with this. But if they are true friends, they will be HAPPY not to smoke weed while they are with you. If they grumble and don't want to accommodate you, then they are not very good friends, and it wouldn't really be that much to give up being with them if you know they don't care enough to help, would it? Addiction if serious and friends and family should be willing to help. You just have to ask. The ones who don't want to help probably have addiction problems of their own. My friend who was giving up alcohol found that several of her family members would not give up alcohol around her. These were people she didn't even see that often, just occasionally at holiday family gatherings. Imagine, they can't give up alcohol for a few hours a few times a year! They would rather give up the delight of her company. Wow, some family, huh?

Please ask your friends. They will want to help if they care about you.

Good luck.
