You're talking about your health and well being. If you're in a situation akin to passing a joint around, you don't have to partake, whether it's using some one else's vape or lending yours. If it's like a nicotine buzz party, why are you there? You should stop smoking and vape exclusively. Like others have suggested, there are so many types of devices, a person that vapes to replace cigarettes has not just more than 1 device, or more than 1 type of device, but several of differing types. Whether driving, sitting at home, going to a party, at work, on the golf course.....there's a device for every activity if you want it to be so, big clouds, little clouds, stealth device, small one, big one... You should do something about being in need of 50-60mg salt nic. A couple different devices for freebase nic.
